-# GitLab Container Registry administration
+---
+redirect_to: 'packages/container_registry.md'
+---
 
-> - [Introduced][ce-4040] in GitLab 8.8.
-> - Container Registry manifest `v1` support was added in GitLab 8.9 to support
->   Docker versions earlier than 1.10.
-> - This document is about the admin guide. To learn how to use GitLab Container
->   Registry [user documentation](../user/project/container_registry.md).
-
-With the Container Registry integrated into GitLab, every project can have its
-own space to store its Docker images.
-
-You can read more about the Container Registry at
-<https://docs.docker.com/registry/introduction/>.
-
-## Enable the Container Registry
-
-**Omnibus GitLab installations**
-
-All you have to do is configure the domain name under which the Container
-Registry will listen to. Read
-[#container-registry-domain-configuration](#container-registry-domain-configuration)
-and pick one of the two options that fits your case.
-
->**Note:**
-The container registry works under HTTPS by default. Using HTTP is possible
-but not recommended and out of the scope of this document.
-Read the [insecure Registry documentation][docker-insecure] if you want to
-implement this.
-
-**Installations from source**
-
-If you have installed GitLab from source:
-
-1. You will have to [install Registry][registry-deploy] by yourself.
-1. After the installation is complete, you will have to configure the Registry's
-   settings in `gitlab.yml` in order to enable it.
-1. Use the sample NGINX configuration file that is found under
-   [`lib/support/nginx/registry-ssl`][registry-ssl] and edit it to match the
-   `host`, `port` and TLS certs paths.
-
-The contents of `gitlab.yml` are:
-
-```
-registry:
-  enabled: true
-  host: registry.gitlab.example.com
-  port: 5005
-  api_url: http://localhost:5000/
-  key: config/registry.key
-  path: shared/registry
-  issuer: gitlab-issuer
-```
-
-where:
-
-| Parameter | Description |
-| --------- | ----------- |
-| `enabled` | `true` or `false`. Enables the Registry in GitLab. By default this is `false`. |
-| `host`    | The host URL under which the Registry will run and the users will be able to use. |
-| `port`    | The port under which the external Registry domain will listen on. |
-| `api_url` | The internal API URL under which the Registry is exposed to. It defaults to `http://localhost:5000`. |
-| `key`     | The private key location that is a pair of Registry's `rootcertbundle`. Read the [token auth configuration documentation][token-config]. |
-| `path`    | This should be the same directory like specified in Registry's `rootdirectory`. Read the [storage configuration documentation][storage-config]. This path needs to be readable by the GitLab user, the web-server user and the Registry user. Read more in [#container-registry-storage-path](#container-registry-storage-path). |
-| `issuer`  | This should be the same value as configured in Registry's `issuer`. Read the [token auth configuration documentation][token-config]. |
-
->**Note:**
-A Registry init file is not shipped with GitLab if you install it from source.
-Hence, [restarting GitLab][restart gitlab] will not restart the Registry should
-you modify its settings. Read the upstream documentation on how to achieve that.
-
-At the **absolute** minimum, make sure your [Registry configuration][registry-auth]
-has `container_registry` as the service and `https://gitlab.example.com/jwt/auth`
-as the realm:
-
-```
-auth:
-  token:
-    realm: https://gitlab.example.com/jwt/auth
-    service: container_registry
-    issuer: gitlab-issuer
-    rootcertbundle: /root/certs/certbundle
-```
-
-CAUTION: **Caution:**
-If `auth` is not set up, users will be able to pull docker images without authentication.
-
-## Container Registry domain configuration
-
-There are two ways you can configure the Registry's external domain.
-
-- Either [use the existing GitLab domain][existing-domain] where in that case
-  the Registry will have to listen on a port and reuse GitLab's TLS certificate,
-- or [use a completely separate domain][new-domain] with a new TLS certificate
-  for that domain.
-
-Since the container Registry requires a TLS certificate, in the end it all boils
-down to how easy or pricey is to get a new one.
-
-Please take this into consideration before configuring the Container Registry
-for the first time.
-
-### Configure Container Registry under an existing GitLab domain
-
-If the Registry is configured to use the existing GitLab domain, you can
-expose the Registry on a port so that you can reuse the existing GitLab TLS
-certificate.
-
-Assuming that the GitLab domain is `https://gitlab.example.com` and the port the
-Registry is exposed to the outside world is `4567`, here is what you need to set
-in `gitlab.rb` or `gitlab.yml` if you are using Omnibus GitLab or installed
-GitLab from source respectively.
-
->**Note:**
-Be careful to choose a port different than the one that Registry listens to (`5000` by default),
-otherwise you will run into conflicts.
-
-**Omnibus GitLab installations**
-
-1. Your `/etc/gitlab/gitlab.rb` should contain the Registry URL as well as the
-   path to the existing TLS certificate and key used by GitLab:
-
-   ```ruby
-   registry_external_url 'https://gitlab.example.com:4567'
-   ```
-
-   Note how the `registry_external_url` is listening on HTTPS under the
-   existing GitLab URL, but on a different port.
-
-   If your TLS certificate is not in `/etc/gitlab/ssl/gitlab.example.com.crt`
-   and key not in `/etc/gitlab/ssl/gitlab.example.com.key` uncomment the lines
-   below:
-
-   ```ruby
-   registry_nginx['ssl_certificate'] = "/path/to/certificate.pem"
-   registry_nginx['ssl_certificate_key'] = "/path/to/certificate.key"
-   ```
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.
-
-1. Validate using:
-
-   ```sh
-   openssl s_client -showcerts -servername gitlab.example.com -connect gitlab.example.com:443 > cacert.pem
-   ```
-
-NOTE: **Note:**
-If your certificate provider provides the CA Bundle certificates, append them to the TLS certificate file.
-
-**Installations from source**
-
-1. Open `/home/git/gitlab/config/gitlab.yml`, find the `registry` entry and
-   configure it with the following settings:
-
-   ```
-   registry:
-     enabled: true
-     host: gitlab.example.com
-     port: 4567
-   ```
-
-1. Save the file and [restart GitLab][] for the changes to take effect.
-1. Make the relevant changes in NGINX as well (domain, port, TLS certificates path).
-
-Users should now be able to login to the Container Registry with their GitLab
-credentials using:
-
-```bash
-docker login gitlab.example.com:4567
-```
-
-### Configure Container Registry under its own domain
-
-If the Registry is configured to use its own domain, you will need a TLS
-certificate for that specific domain (e.g., `registry.example.com`) or maybe
-a wildcard certificate if hosted under a subdomain of your existing GitLab
-domain (e.g., `registry.gitlab.example.com`).
-
-NOTE: **Note:**
-As well as manually generated SSL certificates (explained here), certificates automatically
-generated by Let's Encrypt are also [supported in Omnibus installs](https://docs.gitlab.com/omnibus/settings/ssl.html#host-services).
-
-Let's assume that you want the container Registry to be accessible at
-`https://registry.gitlab.example.com`.
-
-**Omnibus GitLab installations**
-
-1. Place your TLS certificate and key in
-   `/etc/gitlab/ssl/registry.gitlab.example.com.crt` and
-   `/etc/gitlab/ssl/registry.gitlab.example.com.key` and make sure they have
-   correct permissions:
-
-   ```bash
-   chmod 600 /etc/gitlab/ssl/registry.gitlab.example.com.*
-   ```
-
-1. Once the TLS certificate is in place, edit `/etc/gitlab/gitlab.rb` with:
-
-   ```ruby
-   registry_external_url 'https://registry.gitlab.example.com'
-   ```
-
-   Note how the `registry_external_url` is listening on HTTPS.
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.
-
-> **Note:**
-If you have a [wildcard certificate][], you need to specify the path to the
-certificate in addition to the URL, in this case `/etc/gitlab/gitlab.rb` will
-look like:
->
-> ```ruby
-> registry_nginx['ssl_certificate'] = "/etc/gitlab/ssl/certificate.pem"
-> registry_nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/certificate.key"
-> ```
-
-**Installations from source**
-
-1. Open `/home/git/gitlab/config/gitlab.yml`, find the `registry` entry and
-   configure it with the following settings:
-
-   ```yaml
-   registry:
-     enabled: true
-     host: registry.gitlab.example.com
-   ```
-
-1. Save the file and [restart GitLab][] for the changes to take effect.
-1. Make the relevant changes in NGINX as well (domain, port, TLS certificates path).
-
-Users should now be able to login to the Container Registry using their GitLab
-credentials:
-
-```bash
-docker login registry.gitlab.example.com
-```
-
-## Disable Container Registry site-wide
-
->**Note:**
-Disabling the Registry in the Rails GitLab application as set by the following
-steps, will not remove any existing Docker images. This is handled by the
-Registry application itself.
-
-**Omnibus GitLab**
-
-1. Open `/etc/gitlab/gitlab.rb` and set `registry['enable']` to `false`:
-
-   ```ruby
-   registry['enable'] = false
-   ```
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.
-
-**Installations from source**
-
-1. Open `/home/git/gitlab/config/gitlab.yml`, find the `registry` entry and
-   set `enabled` to `false`:
-
-   ```yaml
-   registry:
-     enabled: false
-   ```
-
-1. Save the file and [restart GitLab][] for the changes to take effect.
-
-## Disable Container Registry for new projects site-wide
-
-If the Container Registry is enabled, then it will be available on all new
-projects. To disable this function and let the owners of a project to enable
-the Container Registry by themselves, follow the steps below.
-
-**Omnibus GitLab installations**
-
-1. Edit `/etc/gitlab/gitlab.rb` and add the following line:
-
-   ```ruby
-   gitlab_rails['gitlab_default_projects_features_container_registry'] = false
-   ```
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.
-
-**Installations from source**
-
-1. Open `/home/git/gitlab/config/gitlab.yml`, find the `default_projects_features`
-   entry and configure it so that `container_registry` is set to `false`:
-
-   ```yaml
-   ## Default project features settings
-   default_projects_features:
-     issues: true
-     merge_requests: true
-     wiki: true
-     snippets: false
-     builds: true
-     container_registry: false
-   ```
-
-1. Save the file and [restart GitLab][] for the changes to take effect.
-
-## Container Registry storage path
-
->**Note:**
-For configuring storage in the cloud instead of the filesystem, see the
-[storage driver configuration](#container-registry-storage-driver).
-
-If you want to store your images on the filesystem, you can change the storage
-path for the Container Registry, follow the steps below.
-
-This path is accessible to:
-
-- the user running the Container Registry daemon,
-- the user running GitLab
-
-> **Warning** You should confirm that all GitLab, Registry and web server users
-have access to this directory.
-
-**Omnibus GitLab installations**
-
-The default location where images are stored in Omnibus, is
-`/var/opt/gitlab/gitlab-rails/shared/registry`. To change it:
-
-1. Edit `/etc/gitlab/gitlab.rb`:
-
-   ```ruby
-   gitlab_rails['registry_path'] = "/path/to/registry/storage"
-   ```
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.
-
-**Installations from source**
-
-The default location where images are stored in source installations, is
-`/home/git/gitlab/shared/registry`. To change it:
-
-1. Open `/home/git/gitlab/config/gitlab.yml`, find the `registry` entry and
-   change the `path` setting:
-
-   ```yaml
-   registry:
-     path: shared/registry
-   ```
-
-1. Save the file and [restart GitLab][] for the changes to take effect.
-
-## Container Registry storage driver
-
-You can configure the Container Registry to use a different storage backend by
-configuring a different storage driver. By default the GitLab Container Registry
-is configured to use the filesystem driver, which makes use of [storage path](#container-registry-storage-path)
-configuration.
-
-NOTE: **Note:** Enabling a storage driver other than `filesystem` would mean
-that your Docker client needs to be able to access the storage backend directly.
-In that case, you must use an address that resolves and is accessible outside GitLab server.
-
-The different supported drivers are:
-
-| Driver     | Description                         |
-|------------|-------------------------------------|
-| filesystem | Uses a path on the local filesystem |
-| azure      | Microsoft Azure Blob Storage        |
-| gcs        | Google Cloud Storage                |
-| s3         | Amazon Simple Storage Service. Be sure to configure your storage bucket with the correct [S3 Permission Scopes](https://docs.docker.com/registry/storage-drivers/s3/#s3-permission-scopes).       |
-| swift      | OpenStack Swift Object Storage      |
-| oss        | Aliyun OSS                          |
-
-Read more about the individual driver's config options in the
-[Docker Registry docs][storage-config].
-
-CAUTION: **Warning:** GitLab will not backup Docker images that are not stored on the
-filesystem. Remember to enable backups with your object storage provider if
-desired.
-
-NOTE: **Note:**
-`regionendpoint` is only required when configuring an S3 compatible service such as Minio. It takes a URL such as `http://127.0.0.1:9000`.
-
-**Omnibus GitLab installations**
-
-To configure the `s3` storage driver in Omnibus:
-
-1. Edit `/etc/gitlab/gitlab.rb`:
-
-   ```ruby
-   registry['storage'] = {
-     's3' => {
-       'accesskey' => 's3-access-key',
-       'secretkey' => 's3-secret-key-for-access-key',
-       'bucket' => 'your-s3-bucket',
-       'region' => 'your-s3-region',
-       'regionendpoint' => 'your-s3-regionendpoint'
-     }
-   }
-   ```
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.
-
-**Installations from source**
-
-Configuring the storage driver is done in your registry config YML file created
-when you [deployed your docker registry][registry-deploy].
-
-`s3` storage driver example:
-
-```yml
-storage:
-  s3:
-    accesskey: 'AKIAKIAKI'
-    secretkey: 'secret123'
-    bucket: 'gitlab-registry-bucket-AKIAKIAKI'
-    region: 'your-s3-region'
-    regionendpoint: 'your-s3-regionendpoint'
-  cache:
-    blobdescriptor: inmemory
-  delete:
-    enabled: true
-```
-
-## Change the registry's internal port
-
-> **Note:**
-This is not to be confused with the port that GitLab itself uses to expose
-the Registry to the world.
-
-The Registry server listens on localhost at port `5000` by default,
-which is the address for which the Registry server should accept connections.
-In the examples below we set the Registry's port to `5001`.
-
-**Omnibus GitLab**
-
-1. Open `/etc/gitlab/gitlab.rb` and set `registry['registry_http_addr']`:
-
-   ```ruby
-   registry['registry_http_addr'] = "localhost:5001"
-   ```
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.
-
-**Installations from source**
-
-1. Open the configuration file of your Registry server and edit the
-   [`http:addr`][registry-http-config] value:
-
-   ```yaml
-   http
-     addr: localhost:5001
-   ```
-
-1. Save the file and restart the Registry server.
-
-## Disable Container Registry per project
-
-If Registry is enabled in your GitLab instance, but you don't need it for your
-project, you can disable it from your project's settings. Read the user guide
-on how to achieve that.
-
-## Disable Container Registry but use GitLab as an auth endpoint
-
-**Omnibus GitLab**
-
-You can use GitLab as an auth endpoint and use a non-bundled Container Registry.
-
-1. Open `/etc/gitlab/gitlab.rb` and set necessary configurations:
-
-   ```ruby
-   gitlab_rails['registry_enabled'] = true
-   gitlab_rails['registry_host'] = "registry.gitlab.example.com"
-   gitlab_rails['registry_port'] = "5005"
-   gitlab_rails['registry_api_url'] = "http://localhost:5000"
-   gitlab_rails['registry_path'] = "/var/opt/gitlab/gitlab-rails/shared/registry"
-   gitlab_rails['registry_issuer'] = "omnibus-gitlab-issuer"
-   ```
-
-1. A certificate keypair is required for GitLab and the Container Registry to
-   communicate securely.  By default Omnibus GitLab will generate one keypair,
-   which is saved to `/var/opt/gitlab/gitlab-rails/etc/gitlab-registry.key`.
-   When using a non-bundled Container Registry, you will need to supply a
-   custom certificate key. To do that, add the following to
-   `/etc/gitlab/gitlab.rb`
-
-   ```ruby
-   gitlab_rails['registry_key_path'] = "/custom/path/to/registry-key.key"
-   # registry['internal_key'] should contain the contents of the custom key
-   # file. Line breaks in the key file should be marked using `\n` character
-   # Example:
-   registry['internal_key'] = "---BEGIN RSA PRIVATE KEY---\nMIIEpQIBAA\n"
-   ```
-
-   **Note:** The file specified at `registry_key_path` gets populated with the
-   content specified by `internal_key`, each time reconfigure is executed. If
-   no file is specified, Omnibus GitLab will default it to
-   `/var/opt/gitlab/gitlab-rails/etc/gitlab-registry.key` and will populate
-   it.
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.
-
-**Installations from source**
-
-1. Open `/home/git/gitlab/config/gitlab.yml`, and edit the configuration settings under `registry`:
-
-   ```yaml
-   ## Container Registry
-
-   registry:
-     enabled: true
-     host: "registry.gitlab.example.com"
-     port: "5005"
-     api_url: "http://localhost:5000"
-     path: /var/opt/gitlab/gitlab-rails/shared/registry
-     key: /var/opt/gitlab/gitlab-rails/certificate.key
-     issuer: omnibus-gitlab-issuer
-   ```
-
-1. Save the file and [restart GitLab][] for the changes to take effect.
-
-## Storage limitations
-
-Currently, there is no storage limitation, which means a user can upload an
-infinite amount of Docker images with arbitrary sizes. This setting will be
-configurable in future releases.
-
-## Configure Container Registry notifications
-
-You can configure the Container Registry to send webhook notifications in
-response to events happening within the registry.
-
-Read more about the Container Registry notifications config options in the
-[Docker Registry notifications documentation][notifications-config].
-
->**Note:**
-Multiple endpoints can be configured for the Container Registry.
-
-**Omnibus GitLab installations**
-
-To configure a notification endpoint in Omnibus:
-
-1. Edit `/etc/gitlab/gitlab.rb`:
-
-   ```ruby
-   registry['notifications'] = [
-     {
-       'name' => 'test_endpoint',
-       'url' => 'https://gitlab.example.com/notify',
-       'timeout' => '500ms',
-       'threshold' => 5,
-       'backoff' => '1s',
-       'headers' => {
-         "Authorization" => ["AUTHORIZATION_EXAMPLE_TOKEN"]
-       }
-     }
-   ]
-   ```
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.
-
-**Installations from source**
-
-Configuring the notification endpoint is done in your registry config YML file created
-when you [deployed your docker registry][registry-deploy].
-
-Example:
-
-```
-notifications:
-  endpoints:
-    - name: alistener
-      disabled: false
-      url: https://my.listener.com/event
-      headers: <http.Header>
-      timeout: 500
-      threshold: 5
-      backoff: 1000
-```
-
-## Troubleshooting
-
-### Using self-signed certificates with Container Registry
-
-If you're using a self-signed certificate with your Container Registry, you
-might encounter issues during the CI jobs like the following:

-Error response from daemon: Get registry.example.com/v1/users/: x509: certificate signed by unknown authority
-```
-
-The Docker daemon running the command expects a cert signed by a recognized CA,
-thus the error above.
-
-While GitLab doesn't support using self-signed certificates with Container Registry out of the box, it is possible to make it work by [instructing the docker-daemon to trust the self-signed certificates][docker-insecure-self-signed], mounting the docker-daemon and setting `privileged = false` in the runner's `config.toml`. Setting `privileged = true` takes precedence over the docker-daemon.
-
-```
-  [runners.docker]
-    image = "ruby:2.1"
-    privileged = false
-    volumes = ["/var/run/docker.sock:/var/run/docker.sock", "/cache"]
-```

-### AWS S3 with the GitLab registry error when pushing large images
-
-When using AWS S3 with the GitLab registry, an error may occur when pushing
-large images. Look in the Registry log for the following error:
-
-```
-level=error msg="response completed with error" err.code=unknown err.detail="unexpected EOF" err.message="unknown error"
-```
-
-To resolve the error specify a `chunksize` value in the Registry configuration.
-Start with a value between `25000000` (25MB) and `50000000` (50MB).
-
-**For Omnibus installations**
-
-1. Edit `/etc/gitlab/gitlab.rb`:
-
-   ```ruby
-   registry['storage'] = {
-     's3' => {
-       'accesskey' => 'AKIAKIAKI',
-       'secretkey' => 'secret123',
-       'bucket'    => 'gitlab-registry-bucket-AKIAKIAKI',
-       'chunksize' => 25000000
-     }
-   }
-   ```
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.
-
-**For installations from source**
-
-1. Edit `config/gitlab.yml`:
-
-   ```yaml
-   storage:
-     s3:
-       accesskey: 'AKIAKIAKI'
-       secretkey: 'secret123'
-       bucket:    'gitlab-registry-bucket-AKIAKIAKI'
-       chunksize: 25000000
-   ```
-
-1. Save the file and [restart GitLab][] for the changes to take effect.
-
-### Supporting older Docker clients
-
-As of GitLab 11.9, we began shipping version 2.7.1 of the Docker container registry, which disables the schema1 manifest by default. If you are still using older Docker clients (1.9 or older), you may experience an error pushing images. See [omnibus-4145](https://gitlab.com/gitlab-org/omnibus-gitlab/issues/4145) for more details.
-
-You can add a configuration option for backwards compatibility.
-
-**For Omnibus installations**
-
-1. Edit `/etc/gitlab/gitlab.rb`:
-
-   ```ruby
-   registry['compatibility_schema1_enabled'] = true
-   ```
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.
-
-**For installations from source**
-
-1. Edit the YML configuration file you created when you [deployed the registry][registry-deploy]. Add the following snippet:
-
-   ```yaml
-   compatibility:
-       schema1:
-           enabled: true
-   ```
-
-1. Restart the registry for the changes to take affect.
-
-### Docker connection error
-
-A Docker connection error can occur when there are special characters in either the group,
-project or branch name. Special characters can include:
-
-- Leading underscore
-- Trailing hyphen/dash
-- Double hyphen/dash
-
-To get around this, you can [change the group path](../user/group/index.md#changing-a-groups-path),
-[change the project path](../user/project/settings/index.md#renaming-a-repository) or change the
-branch name. Another option is to create a [push rule](../push_rules/push_rules.html) to prevent
-this at the instance level.
-
-### Image push errors
-
-When getting errors or "retrying" loops in an attempt to push an image but `docker login` works fine,
-there is likely an issue with the headers forwarded to the registry by NGINX. The default recommended
-NGINX configurations should handle this, but it might occur in custom setups where the SSL is
-offloaded to a third party reverse proxy.
-
-This problem was discussed in a [docker project issue][docker-image-push-issue] and a simple solution
-would be to enable relative urls in the registry.
-
-**For Omnibus installations**
-
-1. Edit `/etc/gitlab/gitlab.rb`:
-
-   ```ruby
-   registry['env'] = {
-     "REGISTRY_HTTP_RELATIVEURLS" => true
-   }
-   ```
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.
-
-**For installations from source**
-
-1. Edit the YML configuration file you created when you [deployed the registry][registry-deploy]. Add the following snippet:
-
-   ```yaml
-   http:
-       relativeurls: true
-   ```
-
-1. Restart the registry for the changes to take affect.

+---
 
-> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/7934) in [GitLab Premium](https://about.gitlab.com/pricing/) 11.11.
-
-GitLab can be utilized as a dependency proxy for a variety of common package managers.
-
-This is the administration documentation. If you want to learn how to use the
-dependency proxies, see the [user guide](../user/group/dependency_proxy/index.md).
-
-## Enabling the Dependency Proxy feature
-
-NOTE: **Note:**
-Dependency proxy requires the Puma web server to be enabled.
-Puma support is EXPERIMENTAL at this time.
-
-To enable the Dependency proxy feature:
-
-**Omnibus GitLab installations**
-
-1. Edit `/etc/gitlab/gitlab.rb` and add the following line:
-
-   ```ruby
-   gitlab_rails['dependency_proxy_enabled'] = true
-   ```
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.
-1. Enable the [Puma web server](https://docs.gitlab.com/omnibus/settings/puma.html).
-
-**Installations from source**
-
-1. After the installation is complete, you will have to configure the `dependency_proxy`
-   section in `config/gitlab.yml`. Set to `true` to enable it:
-
-   ```yaml
-   dependency_proxy:
-     enabled: true
-   ```
-
-1. [Restart GitLab] for the changes to take effect.
-1. Enable the [Puma web server](../install/installation.md#using-puma).
-
-## Changing the storage path
-
-By default, the dependency proxy files are stored locally, but you can change the default
-local location or even use object storage.
-
-### Changing the local storage path
-
-The dependency proxy files for Omnibus GitLab installations are stored under
-`/var/opt/gitlab/gitlab-rails/shared/dependency_proxy/` and for source
-installations under `shared/dependency_proxy/` (relative to the Git home directory).
-To change the local storage path:
-
-**Omnibus GitLab installations**
-
-1. Edit `/etc/gitlab/gitlab.rb` and add the following line:
-
-   ```ruby
-   gitlab_rails['dependency_proxy_storage_path'] = "/mnt/dependency_proxy"
-   ```
-
-1. Save the file and [reconfigure GitLab][] for the changes to take effect.

-     storage_path: shared/dependency_proxy
-   ```
-
-1. [Restart GitLab] for the changes to take effect.
-
-### Using object storage
-
-Instead of relying on the local storage, you can use an object storage to
-upload the blobs of the dependency proxy:

-GitLab Packages allows organizations to utilize GitLab as a private repository
-for a variety of common package managers. Users are able to build and publish
-packages, which can be easily consumed as a dependency in downstream projects.
-
-The Packages feature allows GitLab to act as a repository for the following:
-
-| Software repository | Description | Available in GitLab version |
-| ------------------- | ----------- | --------------------------- |
-| [Maven Repository](../user/project/packages/maven_repository.md) | The GitLab Maven Repository enables every project in GitLab to have its own space to store [Maven](https://maven.apache.org/) packages. | 11.3+ |
-| [NPM Registry](../user/project/packages/npm_registry.md)   | The GitLab NPM Registry enables every project in GitLab to have its own space to store [NPM](https://www.npmjs.com/) packages. | 11.7+ |

+# GitLab Container Registry administration
+
+> - [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/4040) in GitLab 8.8.
+> - Container Registry manifest `v1` support was added in GitLab 8.9 to support
+>   Docker versions earlier than 1.10.
+
+NOTE: **Note:**
+This document is about the admin guide. To learn how to use GitLab Container
+Registry [user documentation](../../user/packages/container_registry/index.md).
+
+With the Container Registry integrated into GitLab, every project can have its
+own space to store its Docker images.
+
+You can read more about the Docker Registry at
+<https://docs.docker.com/registry/introduction/>.
+
+## Enable the Container Registry
+
+**Omnibus GitLab installations**
+
+All you have to do is configure the domain name under which the Container
+Registry will listen to. Read
+[#container-registry-domain-configuration](#container-registry-domain-configuration)
+and pick one of the two options that fits your case.
+
+NOTE: **Note:**
+The container registry works under HTTPS by default. Using HTTP is possible
+but not recommended and out of the scope of this document.
+Read the [insecure Registry documentation](https://docs.docker.com/registry/insecure/)
+if you want to implement this.
+
+**Installations from source**
+
+If you have installed GitLab from source:
+
+1. You will have to [install Registry](https://docs.docker.com/registry/deploying/) by yourself.
+1. After the installation is complete, you will have to configure the Registry's
+   settings in `gitlab.yml` in order to enable it.
+1. Use the sample NGINX configuration file that is found under
+   [`lib/support/nginx/registry-ssl`](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/lib/support/nginx/registry-ssl) and edit it to match the
+   `host`, `port` and TLS certs paths.
+
+The contents of `gitlab.yml` are:
+
+```yaml
+registry:
+  enabled: true
+  host: registry.gitlab.example.com
+  port: 5005
+  api_url: http://localhost:5000/
+  key: config/registry.key
+  path: shared/registry
+  issuer: gitlab-issuer
+```
+
+where:
+
+| Parameter | Description |
+| --------- | ----------- |
+| `enabled` | `true` or `false`. Enables the Registry in GitLab. By default this is `false`. |
+| `host`    | The host URL under which the Registry will run and the users will be able to use. |
+| `port`    | The port under which the external Registry domain will listen on. |
+| `api_url` | The internal API URL under which the Registry is exposed to. It defaults to `http://localhost:5000`. |
+| `key`     | The private key location that is a pair of Registry's `rootcertbundle`. Read the [token auth configuration documentation](https://docs.docker.com/registry/configuration/#token). |
+| `path`    | This should be the same directory like specified in Registry's `rootdirectory`. Read the [storage configuration documentation](https://docs.docker.com/registry/configuration/#storage). This path needs to be readable by the GitLab user, the web-server user and the Registry user. Read more in [#container-registry-storage-path](#container-registry-storage-path). |
+| `issuer`  | This should be the same value as configured in Registry's `issuer`. Read the [token auth configuration documentation](https://docs.docker.com/registry/configuration/#token). |
+
+NOTE: **Note:**
+A Registry init file is not shipped with GitLab if you install it from source.
+Hence, [restarting GitLab](../restart_gitlab.md#installations-from-source) will not restart the Registry should
+you modify its settings. Read the upstream documentation on how to achieve that.
+
+At the **absolute** minimum, make sure your [Registry configuration](https://docs.docker.com/registry/configuration/#auth)
+has `container_registry` as the service and `https://gitlab.example.com/jwt/auth`
+as the realm:
+
+```yaml
+auth:
+  token:
+    realm: https://gitlab.example.com/jwt/auth
+    service: container_registry
+    issuer: gitlab-issuer
+    rootcertbundle: /root/certs/certbundle
+```
+
+CAUTION: **Caution:**
+If `auth` is not set up, users will be able to pull docker images without authentication.
+
+## Container Registry domain configuration
+
+There are two ways you can configure the Registry's external domain. Either:
+
+- [Use the existing GitLab domain](#configure-container-registry-under-an-existing-gitlab-domain) where in that case
+  the Registry will have to listen on a port and reuse GitLab's TLS certificate,
+- [Use a completely separate domain](#configure-container-registry-under-its-own-domain) with a new TLS certificate
+  for that domain.
+
+Since the container Registry requires a TLS certificate, in the end it all boils
+down to how easy or pricey is to get a new one.
+
+Please take this into consideration before configuring the Container Registry
+for the first time.
+
+### Configure Container Registry under an existing GitLab domain
+
+If the Registry is configured to use the existing GitLab domain, you can
+expose the Registry on a port so that you can reuse the existing GitLab TLS
+certificate.
+
+Assuming that the GitLab domain is `https://gitlab.example.com` and the port the
+Registry is exposed to the outside world is `4567`, here is what you need to set
+in `gitlab.rb` or `gitlab.yml` if you are using Omnibus GitLab or installed
+GitLab from source respectively.
+
+NOTE: **Note:**
+Be careful to choose a port different than the one that Registry listens to (`5000` by default),
+otherwise you will run into conflicts.
+
+**Omnibus GitLab installations**
+
+1. Your `/etc/gitlab/gitlab.rb` should contain the Registry URL as well as the
+   path to the existing TLS certificate and key used by GitLab:
+
+   ```ruby
+   registry_external_url 'https://gitlab.example.com:4567'
+   ```
+
+   Note how the `registry_external_url` is listening on HTTPS under the
+   existing GitLab URL, but on a different port.
+
+   If your TLS certificate is not in `/etc/gitlab/ssl/gitlab.example.com.crt`
+   and key not in `/etc/gitlab/ssl/gitlab.example.com.key` uncomment the lines
+   below:
+
+   ```ruby
+   registry_nginx['ssl_certificate'] = "/path/to/certificate.pem"
+   registry_nginx['ssl_certificate_key'] = "/path/to/certificate.key"
+   ```
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure)
+   for the changes to take effect.
+
+1. Validate using:
+
+   ```sh
+   openssl s_client -showcerts -servername gitlab.example.com -connect gitlab.example.com:443 > cacert.pem
+   ```
+
+NOTE: **Note:**
+If your certificate provider provides the CA Bundle certificates, append them to the TLS certificate file.
+
+**Installations from source**
+
+1. Open `/home/git/gitlab/config/gitlab.yml`, find the `registry` entry and
+   configure it with the following settings:
+
+   ```
+   registry:
+     enabled: true
+     host: gitlab.example.com
+     port: 4567
+   ```
+
+1. Save the file and [restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
+1. Make the relevant changes in NGINX as well (domain, port, TLS certificates path).
+
+Users should now be able to login to the Container Registry with their GitLab
+credentials using:
+
+```bash
+docker login gitlab.example.com:4567
+```
+
+### Configure Container Registry under its own domain
+
+If the Registry is configured to use its own domain, you will need a TLS
+certificate for that specific domain (e.g., `registry.example.com`) or maybe
+a wildcard certificate if hosted under a subdomain of your existing GitLab
+domain (e.g., `registry.gitlab.example.com`).
+
+NOTE: **Note:**
+As well as manually generated SSL certificates (explained here), certificates automatically
+generated by Let's Encrypt are also [supported in Omnibus installs](https://docs.gitlab.com/omnibus/settings/ssl.html#host-services).
+
+Let's assume that you want the container Registry to be accessible at
+`https://registry.gitlab.example.com`.
+
+**Omnibus GitLab installations**
+
+1. Place your TLS certificate and key in
+   `/etc/gitlab/ssl/registry.gitlab.example.com.crt` and
+   `/etc/gitlab/ssl/registry.gitlab.example.com.key` and make sure they have
+   correct permissions:
+
+   ```bash
+   chmod 600 /etc/gitlab/ssl/registry.gitlab.example.com.*
+   ```
+
+1. Once the TLS certificate is in place, edit `/etc/gitlab/gitlab.rb` with:
+
+   ```ruby
+   registry_external_url 'https://registry.gitlab.example.com'
+   ```
+
+   Note how the `registry_external_url` is listening on HTTPS.
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
+
+If you have a [wildcard certificate](https://en.wikipedia.org/wiki/Wildcard_certificate), you need to specify the path to the
+certificate in addition to the URL, in this case `/etc/gitlab/gitlab.rb` will
+look like:
+
+```ruby
+registry_nginx['ssl_certificate'] = "/etc/gitlab/ssl/certificate.pem"
+registry_nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/certificate.key"
+```
+
+**Installations from source**
+
+1. Open `/home/git/gitlab/config/gitlab.yml`, find the `registry` entry and
+   configure it with the following settings:
+
+   ```yaml
+   registry:
+     enabled: true
+     host: registry.gitlab.example.com
+   ```
+
+1. Save the file and [restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
+1. Make the relevant changes in NGINX as well (domain, port, TLS certificates path).
+
+Users should now be able to login to the Container Registry using their GitLab
+credentials:
+
+```bash
+docker login registry.gitlab.example.com
+```
+
+## Disable Container Registry site-wide
+
+NOTE: **Note:**
+Disabling the Registry in the Rails GitLab application as set by the following
+steps, will not remove any existing Docker images. This is handled by the
+Registry application itself.
+
+**Omnibus GitLab**
+
+1. Open `/etc/gitlab/gitlab.rb` and set `registry['enable']` to `false`:
+
+   ```ruby
+   registry['enable'] = false
+   ```
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
+
+**Installations from source**
+
+1. Open `/home/git/gitlab/config/gitlab.yml`, find the `registry` entry and
+   set `enabled` to `false`:
+
+   ```yaml
+   registry:
+     enabled: false
+   ```
+
+1. Save the file and [restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
+
+## Disable Container Registry for new projects site-wide
+
+If the Container Registry is enabled, then it will be available on all new
+projects. To disable this function and let the owners of a project to enable
+the Container Registry by themselves, follow the steps below.
+
+**Omnibus GitLab installations**
+
+1. Edit `/etc/gitlab/gitlab.rb` and add the following line:
+
+   ```ruby
+   gitlab_rails['gitlab_default_projects_features_container_registry'] = false
+   ```
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
+
+**Installations from source**
+
+1. Open `/home/git/gitlab/config/gitlab.yml`, find the `default_projects_features`
+   entry and configure it so that `container_registry` is set to `false`:
+
+   ```yaml
+   ## Default project features settings
+   default_projects_features:
+     issues: true
+     merge_requests: true
+     wiki: true
+     snippets: false
+     builds: true
+     container_registry: false
+   ```
+
+1. Save the file and [restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
+
+## Container Registry storage path
+
+NOTE: **Note:**
+For configuring storage in the cloud instead of the filesystem, see the
+[storage driver configuration](#container-registry-storage-driver).
+
+If you want to store your images on the filesystem, you can change the storage
+path for the Container Registry, follow the steps below.
+
+This path is accessible to:
+
+- The user running the Container Registry daemon.
+- The user running GitLab.
+
+CAUTION: **Warning** You should confirm that all GitLab, Registry and web server users
+have access to this directory.
+
+**Omnibus GitLab installations**
+
+The default location where images are stored in Omnibus, is
+`/var/opt/gitlab/gitlab-rails/shared/registry`. To change it:
+
+1. Edit `/etc/gitlab/gitlab.rb`:
+
+   ```ruby
+   gitlab_rails['registry_path'] = "/path/to/registry/storage"
+   ```
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
+
+**Installations from source**
+
+The default location where images are stored in source installations, is
+`/home/git/gitlab/shared/registry`. To change it:
+
+1. Open `/home/git/gitlab/config/gitlab.yml`, find the `registry` entry and
+   change the `path` setting:
+
+   ```yaml
+   registry:
+     path: shared/registry
+   ```
+
+1. Save the file and [restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
+
+## Container Registry storage driver
+
+You can configure the Container Registry to use a different storage backend by
+configuring a different storage driver. By default the GitLab Container Registry
+is configured to use the filesystem driver, which makes use of [storage path](#container-registry-storage-path)
+configuration.
+
+NOTE: **Note:** Enabling a storage driver other than `filesystem` would mean
+that your Docker client needs to be able to access the storage backend directly.
+In that case, you must use an address that resolves and is accessible outside GitLab server.
+
+The different supported drivers are:
+
+| Driver     | Description                         |
+|------------|-------------------------------------|
+| filesystem | Uses a path on the local filesystem |
+| azure      | Microsoft Azure Blob Storage        |
+| gcs        | Google Cloud Storage                |
+| s3         | Amazon Simple Storage Service. Be sure to configure your storage bucket with the correct [S3 Permission Scopes](https://docs.docker.com/registry/storage-drivers/s3/#s3-permission-scopes).       |
+| swift      | OpenStack Swift Object Storage      |
+| oss        | Aliyun OSS                          |
+
+Read more about the individual driver's config options in the
+[Docker Registry docs](https://docs.docker.com/registry/configuration/#storage).
+
+CAUTION: **Warning:** GitLab will not backup Docker images that are not stored on the
+filesystem. Remember to enable backups with your object storage provider if
+desired.
+
+NOTE: **Note:**
+`regionendpoint` is only required when configuring an S3 compatible service such as Minio. It takes a URL such as `http://127.0.0.1:9000`.
+
+**Omnibus GitLab installations**
+
+To configure the `s3` storage driver in Omnibus:
+
+1. Edit `/etc/gitlab/gitlab.rb`:
+
+   ```ruby
+   registry['storage'] = {
+     's3' => {
+       'accesskey' => 's3-access-key',
+       'secretkey' => 's3-secret-key-for-access-key',
+       'bucket' => 'your-s3-bucket',
+       'region' => 'your-s3-region',
+       'regionendpoint' => 'your-s3-regionendpoint'
+     }
+   }
+   ```
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
+
+**Installations from source**
+
+Configuring the storage driver is done in your registry config YML file created
+when you [deployed your docker registry](https://docs.docker.com/registry/deploying/).
+
+`s3` storage driver example:
+
+```yml
+storage:
+  s3:
+    accesskey: 'AKIAKIAKI'
+    secretkey: 'secret123'
+    bucket: 'gitlab-registry-bucket-AKIAKIAKI'
+    region: 'your-s3-region'
+    regionendpoint: 'your-s3-regionendpoint'
+  cache:
+    blobdescriptor: inmemory
+  delete:
+    enabled: true
+```
+
+## Change the registry's internal port
+
+NOTE: **Note:**
+This is not to be confused with the port that GitLab itself uses to expose
+the Registry to the world.
+
+The Registry server listens on localhost at port `5000` by default,
+which is the address for which the Registry server should accept connections.
+In the examples below we set the Registry's port to `5001`.
+
+**Omnibus GitLab**
+
+1. Open `/etc/gitlab/gitlab.rb` and set `registry['registry_http_addr']`:
+
+   ```ruby
+   registry['registry_http_addr'] = "localhost:5001"
+   ```
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
+
+**Installations from source**
+
+1. Open the configuration file of your Registry server and edit the
+   [`http:addr`](https://docs.docker.com/registry/configuration/#http) value:
+
+   ```yaml
+   http
+     addr: localhost:5001
+   ```
+
+1. Save the file and restart the Registry server.
+
+## Disable Container Registry per project
+
+If Registry is enabled in your GitLab instance, but you don't need it for your
+project, you can disable it from your project's settings. Read the user guide
+on how to achieve that.
+
+## Disable Container Registry but use GitLab as an auth endpoint
+
+**Omnibus GitLab**
+
+You can use GitLab as an auth endpoint and use a non-bundled Container Registry.
+
+1. Open `/etc/gitlab/gitlab.rb` and set necessary configurations:
+
+   ```ruby
+   gitlab_rails['registry_enabled'] = true
+   gitlab_rails['registry_host'] = "registry.gitlab.example.com"
+   gitlab_rails['registry_port'] = "5005"
+   gitlab_rails['registry_api_url'] = "http://localhost:5000"
+   gitlab_rails['registry_path'] = "/var/opt/gitlab/gitlab-rails/shared/registry"
+   gitlab_rails['registry_issuer'] = "omnibus-gitlab-issuer"
+   ```
+
+1. A certificate keypair is required for GitLab and the Container Registry to
+   communicate securely.  By default Omnibus GitLab will generate one keypair,
+   which is saved to `/var/opt/gitlab/gitlab-rails/etc/gitlab-registry.key`.
+   When using a non-bundled Container Registry, you will need to supply a
+   custom certificate key. To do that, add the following to
+   `/etc/gitlab/gitlab.rb`
+
+   ```ruby
+   gitlab_rails['registry_key_path'] = "/custom/path/to/registry-key.key"
+   # registry['internal_key'] should contain the contents of the custom key
+   # file. Line breaks in the key file should be marked using `\n` character
+   # Example:
+   registry['internal_key'] = "---BEGIN RSA PRIVATE KEY---\nMIIEpQIBAA\n"
+   ```
+
+   NOTE: **Note:**
+   The file specified at `registry_key_path` gets populated with the
+   content specified by `internal_key`, each time reconfigure is executed. If
+   no file is specified, Omnibus GitLab will default it to
+   `/var/opt/gitlab/gitlab-rails/etc/gitlab-registry.key` and will populate
+   it.
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
+
+**Installations from source**
+
+1. Open `/home/git/gitlab/config/gitlab.yml`, and edit the configuration settings under `registry`:
+
+   ```yaml
+   ## Container Registry
+
+   registry:
+     enabled: true
+     host: "registry.gitlab.example.com"
+     port: "5005"
+     api_url: "http://localhost:5000"
+     path: /var/opt/gitlab/gitlab-rails/shared/registry
+     key: /var/opt/gitlab/gitlab-rails/certificate.key
+     issuer: omnibus-gitlab-issuer
+   ```
+
+1. Save the file and [restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
+
+## Storage limitations
+
+Currently, there is no storage limitation, which means a user can upload an
+infinite amount of Docker images with arbitrary sizes. This setting will be
+configurable in future releases.
+
+## Configure Container Registry notifications
+
+You can configure the Container Registry to send webhook notifications in
+response to events happening within the registry.
+
+Read more about the Container Registry notifications config options in the
+[Docker Registry notifications documentation](https://docs.docker.com/registry/notifications/).
+
+NOTE: **Note:**
+Multiple endpoints can be configured for the Container Registry.
+
+**Omnibus GitLab installations**
+
+To configure a notification endpoint in Omnibus:
+
+1. Edit `/etc/gitlab/gitlab.rb`:
+
+   ```ruby
+   registry['notifications'] = [
+     {
+       'name' => 'test_endpoint',
+       'url' => 'https://gitlab.example.com/notify',
+       'timeout' => '500ms',
+       'threshold' => 5,
+       'backoff' => '1s',
+       'headers' => {
+         "Authorization" => ["AUTHORIZATION_EXAMPLE_TOKEN"]
+       }
+     }
+   ]
+   ```
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
+
+**Installations from source**
+
+Configuring the notification endpoint is done in your registry config YML file created
+when you [deployed your docker registry](https://docs.docker.com/registry/deploying/).
+
+Example:
+
+```yaml
+notifications:
+  endpoints:
+    - name: alistener
+      disabled: false
+      url: https://my.listener.com/event
+      headers: <http.Header>
+      timeout: 500
+      threshold: 5
+      backoff: 1000
+```
+
+## Troubleshooting
+
+Before diving in to the following sections, here's some basic troubleshooting:
+
+1. Check to make sure that the system clock on your Docker client and GitLab server have
+   been synchronized (e.g. via NTP).
+
+1. If you are using an S3-backed Registry, double check that the IAM
+   permissions and the S3 credentials (including region) are correct. See [the
+   sample IAM policy](https://docs.docker.com/registry/storage-drivers/s3/)
+   for more details.
+
+1. Check the Registry logs (e.g. `/var/log/gitlab/registry/current`) and the GitLab production logs
+   for errors (e.g. `/var/log/gitlab/gitlab-rails/production.log`). You may be able to find clues
+   there.
+
+### Using self-signed certificates with Container Registry
+
+If you're using a self-signed certificate with your Container Registry, you
+might encounter issues during the CI jobs like the following:
+
+```
+Error response from daemon: Get registry.example.com/v1/users/: x509: certificate signed by unknown authority
+```
+
+The Docker daemon running the command expects a cert signed by a recognized CA,
+thus the error above.
+
+While GitLab doesn't support using self-signed certificates with Container
+Registry out of the box, it is possible to make it work by
+[instructing the docker-daemon to trust the self-signed certificates](https://docs.docker.com/registry/insecure/#use-self-signed-certificates),
+mounting the docker-daemon and setting `privileged = false` in the Runner's
+`config.toml`. Setting `privileged = true` takes precedence over the docker-daemon:
+
+```toml
+  [runners.docker]
+    image = "ruby:2.1"
+    privileged = false
+    volumes = ["/var/run/docker.sock:/var/run/docker.sock", "/cache"]
+```
+
+Additional information about this: [issue 18239](https://gitlab.com/gitlab-org/gitlab-ce/issues/18239).
+
+### AWS S3 with the GitLab registry error when pushing large images
+
+When using AWS S3 with the GitLab registry, an error may occur when pushing
+large images. Look in the Registry log for the following error:
+
+```
+level=error msg="response completed with error" err.code=unknown err.detail="unexpected EOF" err.message="unknown error"
+```
+
+To resolve the error specify a `chunksize` value in the Registry configuration.
+Start with a value between `25000000` (25MB) and `50000000` (50MB).
+
+**For Omnibus installations**
+
+1. Edit `/etc/gitlab/gitlab.rb`:
+
+   ```ruby
+   registry['storage'] = {
+     's3' => {
+       'accesskey' => 'AKIAKIAKI',
+       'secretkey' => 'secret123',
+       'bucket'    => 'gitlab-registry-bucket-AKIAKIAKI',
+       'chunksize' => 25000000
+     }
+   }
+   ```
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
+
+**For installations from source**
+
+1. Edit `config/gitlab.yml`:
+
+   ```yaml
+   storage:
+     s3:
+       accesskey: 'AKIAKIAKI'
+       secretkey: 'secret123'
+       bucket:    'gitlab-registry-bucket-AKIAKIAKI'
+       chunksize: 25000000
+   ```
+
+1. Save the file and [restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
+
+### Supporting older Docker clients
+
+As of GitLab 11.9, we began shipping version 2.7.1 of the Docker container registry, which disables the schema1 manifest by default. If you are still using older Docker clients (1.9 or older), you may experience an error pushing images. See [omnibus-4145](https://gitlab.com/gitlab-org/omnibus-gitlab/issues/4145) for more details.
+
+You can add a configuration option for backwards compatibility.
+
+**For Omnibus installations**
+
+1. Edit `/etc/gitlab/gitlab.rb`:
+
+   ```ruby
+   registry['compatibility_schema1_enabled'] = true
+   ```
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
+
+**For installations from source**
+
+1. Edit the YML configuration file you created when you [deployed the registry](https://docs.docker.com/registry/deploying/). Add the following snippet:
+
+   ```yaml
+   compatibility:
+       schema1:
+           enabled: true
+   ```
+
+1. Restart the registry for the changes to take affect.
+
+### Docker connection error
+
+A Docker connection error can occur when there are special characters in either the group,
+project or branch name. Special characters can include:
+
+- Leading underscore
+- Trailing hyphen/dash
+- Double hyphen/dash
+
+To get around this, you can [change the group path](../../user/group/index.md#changing-a-groups-path),
+[change the project path](../../user/project/settings/index.md#renaming-a-repository) or change the
+branch name. Another option is to create a [push rule](../../push_rules/push_rules.html) to prevent
+this at the instance level.
+
+### Image push errors
+
+When getting errors or "retrying" loops in an attempt to push an image but `docker login` works fine,
+there is likely an issue with the headers forwarded to the registry by NGINX. The default recommended
+NGINX configurations should handle this, but it might occur in custom setups where the SSL is
+offloaded to a third party reverse proxy.
+
+This problem was discussed in a [docker project issue](https://github.com/docker/distribution/issues/970)
+and a simple solution would be to enable relative URLs in the Registry.
+
+**For Omnibus installations**
+
+1. Edit `/etc/gitlab/gitlab.rb`:
+
+   ```ruby
+   registry['env'] = {
+     "REGISTRY_HTTP_RELATIVEURLS" => true
+   }
+   ```
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
+
+**For installations from source**
+
+1. Edit the YML configuration file you created when you [deployed the registry](https://docs.docker.com/registry/deploying/). Add the following snippet:
+
+   ```yaml
+   http:
+       relativeurls: true
+   ```
+
+1. Save the file and [restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
+
+### Enable the Registry debug server
+
+The optional debug server can be enabled by setting the registry debug address
+in your `gitlab.rb` configuration.
+
+```ruby
+registry['debug_addr'] = "localhost:5001"
+```
+
+After adding the setting, [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) to apply the change.
+
+Use curl to request debug output from the debug server:
+
+```bash
+curl localhost:5001/debug/health
+curl localhost:5001/debug/vars
+```
+
+### Advanced Troubleshooting
+
+NOTE: **Note:**
+The following section is only recommended for experts.
+
+Sometimes it's not obvious what is wrong, and you may need to dive deeper into
+the communication between the Docker client and the Registry to find out
+what's wrong. We will use a concrete example in the past to illustrate how to
+diagnose a problem with the S3 setup.
+
+#### Unexpected 403 error during push
+
+A user attempted to enable an S3-backed Registry. The `docker login` step went
+fine. However, when pushing an image, the output showed:
+
+```text
+The push refers to a repository [s3-testing.myregistry.com:4567/root/docker-test/docker-image]
+dc5e59c14160: Pushing [==================================================>] 14.85 kB
+03c20c1a019a: Pushing [==================================================>] 2.048 kB
+a08f14ef632e: Pushing [==================================================>] 2.048 kB
+228950524c88: Pushing 2.048 kB
+6a8ecde4cc03: Pushing [==>                                                ] 9.901 MB/205.7 MB
+5f70bf18a086: Pushing 1.024 kB
+737f40e80b7f: Waiting
+82b57dbc5385: Waiting
+19429b698a22: Waiting
+9436069b92a3: Waiting
+error parsing HTTP 403 response body: unexpected end of JSON input: ""
+```
+
+This error is ambiguous, as it's not clear whether the 403 is coming from the
+GitLab Rails application, the Docker Registry, or something else. In this
+case, since we know that since the login succeeded, we probably need to look
+at the communication between the client and the Registry.
+
+The REST API between the Docker client and Registry is [described
+here](https://docs.docker.com/registry/spec/api/). Normally, one would just
+use Wireshark or tcpdump to capture the traffic and see where things went
+wrong. However, since all communications between Docker clients and servers
+are done over HTTPS, it's a bit difficult to decrypt the traffic quickly even
+if you know the private key. What can we do instead?
+
+One way would be to disable HTTPS by setting up an [insecure
+Registry](https://docs.docker.com/registry/insecure/). This could introduce a
+security hole and is only recommended for local testing. If you have a
+production system and can't or don't want to do this, there is another way:
+use mitmproxy, which stands for Man-in-the-Middle Proxy.
+
+#### mitmproxy
+
+[mitmproxy](https://mitmproxy.org/) allows you to place a proxy between your
+client and server to inspect all traffic. One wrinkle is that your system
+needs to trust the mitmproxy SSL certificates for this to work.
+
+The following installation instructions assume you are running Ubuntu:
+
+1. [Install mitmproxy](https://docs.mitmproxy.org/stable/overview-installation/).
+1. Run `mitmproxy --port 9000` to generate its certificates.
+   Enter <kbd>CTRL</kbd>-<kbd>C</kbd> to quit.
+1. Install the certificate from `~/.mitmproxy` to your system:
+
+   ```sh
+   sudo cp ~/.mitmproxy/mitmproxy-ca-cert.pem /usr/local/share/ca-certificates/mitmproxy-ca-cert.crt
+   sudo update-ca-certificates
+   ```
+
+If successful, the output should indicate that a certificate was added:
+
+```sh
+Updating certificates in /etc/ssl/certs... 1 added, 0 removed; done.
+Running hooks in /etc/ca-certificates/update.d....done.
+```
+
+To verify that the certificates are properly installed, run:
+
+```sh
+mitmproxy --port 9000
+```
+
+This will run mitmproxy on port `9000`. In another window, run:
+
+```sh
+curl --proxy http://localhost:9000 https://httpbin.org/status/200
+```
+
+If everything is set up correctly, you will see information on the mitmproxy window and
+no errors from the curl commands.
+
+#### Running the Docker daemon with a proxy
+
+For Docker to connect through a proxy, you must start the Docker daemon with the
+proper environment variables. The easiest way is to shutdown Docker (e.g. `sudo initctl stop docker`)
+and then run Docker by hand. As root, run:
+
+```sh
+export HTTP_PROXY="http://localhost:9000"
+export HTTPS_PROXY="https://localhost:9000"
+docker daemon --debug
+```
+
+This will launch the Docker daemon and proxy all connections through mitmproxy.
+
+#### Running the Docker client
+
+Now that we have mitmproxy and Docker running, we can attempt to login and push
+a container image. You may need to run as root to do this. For example:
+
+```sh
+docker login s3-testing.myregistry.com:4567
+docker push s3-testing.myregistry.com:4567/root/docker-test/docker-image
+```
+
+In the example above, we see the following trace on the mitmproxy window:
+
+![mitmproxy output from Docker](img/mitmproxy-docker.png)
+
+The above image shows:
+
+- The initial PUT requests went through fine with a 201 status code.
+- The 201 redirected the client to the S3 bucket.
+- The HEAD request to the AWS bucket reported a 403 Unauthorized.
+
+What does this mean? This strongly suggests that the S3 user does not have the right
+[permissions to perform a HEAD request](http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectHEAD.html).
+The solution: check the [IAM permissions again](https://docs.docker.com/registry/storage-drivers/s3/).
+Once the right permissions were set, the error will go away.

+# GitLab Dependency Proxy administration **(PREMIUM ONLY)**
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/7934) in [GitLab Premium](https://about.gitlab.com/pricing/) 11.11.
+
+GitLab can be utilized as a dependency proxy for a variety of common package managers.
+
+This is the administration documentation. If you want to learn how to use the
+dependency proxies, see the [user guide](../../user/group/dependency_proxy/index.md).
+
+## Enabling the Dependency Proxy feature
+
+NOTE: **Note:**
+Dependency proxy requires the Puma web server to be enabled.
+Puma support is EXPERIMENTAL at this time.
+
+To enable the Dependency proxy feature:
+
+**Omnibus GitLab installations**
+
+1. Edit `/etc/gitlab/gitlab.rb` and add the following line:
+
+   ```ruby
+   gitlab_rails['dependency_proxy_enabled'] = true
+   ```
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure "How to reconfigure Omnibus GitLab") for the changes to take effect.
+1. Enable the [Puma web server](https://docs.gitlab.com/omnibus/settings/puma.html).
+
+**Installations from source**
+
+1. After the installation is complete, you will have to configure the `dependency_proxy`
+   section in `config/gitlab.yml`. Set to `true` to enable it:
+
+   ```yaml
+   dependency_proxy:
+     enabled: true
+   ```
+
+1. [Restart GitLab](../restart_gitlab.md#installations-from-source "How to restart GitLab") for the changes to take effect.
+1. Enable the [Puma web server](../../install/installation.md#using-puma).
+
+## Changing the storage path
+
+By default, the dependency proxy files are stored locally, but you can change the default
+local location or even use object storage.
+
+### Changing the local storage path
+
+The dependency proxy files for Omnibus GitLab installations are stored under
+`/var/opt/gitlab/gitlab-rails/shared/dependency_proxy/` and for source
+installations under `shared/dependency_proxy/` (relative to the Git home directory).
+To change the local storage path:
+
+**Omnibus GitLab installations**
+
+1. Edit `/etc/gitlab/gitlab.rb` and add the following line:
+
+   ```ruby
+   gitlab_rails['dependency_proxy_storage_path'] = "/mnt/dependency_proxy"
+   ```
+
+1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure "How to reconfigure Omnibus GitLab") for the changes to take effect.
+
+**Installations from source**
+
+1. Edit the `dependency_proxy` section in `config/gitlab.yml`:
+
+   ```yaml
+   dependency_proxy:
+     enabled: true
+     storage_path: shared/dependency_proxy
+   ```
+
+1. [Restart GitLab](../restart_gitlab.md#installations-from-source "How to restart GitLab") for the changes to take effect.
+
+### Using object storage
+
+Instead of relying on the local storage, you can use an object storage to
+upload the blobs of the dependency proxy:
+
+**Omnibus GitLab installations**
+
+1. Edit `/etc/gitlab/gitlab.rb` and add the following lines (uncomment where
+   necessary):
+
+   ```ruby
+   gitlab_rails['dependency_proxy_enabled'] = true
+   gitlab_rails['dependency_proxy_storage_path'] = "/var/opt/gitlab/gitlab-rails/shared/dependency_proxy"

+# GitLab Package Registry administration **(PREMIUM ONLY)**
+
+GitLab Packages allows organizations to utilize GitLab as a private repository
+for a variety of common package managers. Users are able to build and publish
+packages, which can be easily consumed as a dependency in downstream projects.
+
+The Packages feature allows GitLab to act as a repository for the following:
+
+| Software repository | Description | Available in GitLab version |
+| ------------------- | ----------- | --------------------------- |
+| [Maven Repository](../../user/packages/maven_repository/index.md) | The GitLab Maven Repository enables every project in GitLab to have its own space to store [Maven](https://maven.apache.org/) packages. | 11.3+ |
+| [NPM Registry](../../user/packages/npm_registry/index.md)   | The GitLab NPM Registry enables every project in GitLab to have its own space to store [NPM](https://www.npmjs.com/) packages. | 11.7+ |
+
+Don't you see your package management system supported yet?
+Please consider contributing
+to GitLab. This [development documentation](../../development/packages.md) will guide you through the process.
+
+## Enabling the Packages feature
+
+NOTE: **Note:**
+After the Packages feature is enabled, the repositories are available
+for all new projects by default. To enable it for existing projects, users will
+have to explicitly do so in the project's settings.

+# GitLab Container Registry
+
+> - [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/4040) in GitLab 8.8.
+> - Docker Registry manifest `v1` support was added in GitLab 8.9 to support Docker

+> - Starting from GitLab 8.12, if you have 2FA enabled in your account, you need
+>   to pass a [personal access token](../../profile/personal_access_tokens.md) instead of your password in order to
+>   login to GitLab's Container Registry.
+> - Multiple level image names support was added in GitLab 9.1.
+
+NOTE: **Note:**
+This document is the user guide. To learn how to enable GitLab Container
+Registry across your GitLab instance, visit the
+[administrator documentation](../../../administration/packages/container_registry.md).
+
+With the Docker Container Registry integrated into GitLab, every project can
+have its own space to store its Docker images.
+
+You can read more about Docker Registry at <https://docs.docker.com/registry/introduction/>.
+
+## Enable the Container Registry for your project
+
+If you cannot find the **Packages > Container Registry** entry under your
+project's sidebar, it is not enabled in your GitLab instance. Ask your
+administrator to enable GitLab Container Registry following the
+[administration documentation](../../../administration/packages/container_registry.md).
+
+If you are using GitLab.com, this is enabled by default so you can start using
+the Registry immediately. Currently there is a soft (10GB) size restriction for
+Registry on GitLab.com, as part of the [repository size limit](../../project/repository/index.md).
+
+Once enabled for your GitLab instance, to enable Container Registry for your
+project:
+
+1. Go to your project's **Settings > General** page.
+1. Expand the **Visibility, project features, permissions** section
+   and enable the **Container Registry** feature on your project. For new
+   projects this might be enabled by default. For existing projects
+   (prior GitLab 8.8), you will have to explicitly enable it.
+1. Press **Save changes** for the changes to take effect. You should now be able
+   to see the **Packages > Container Registry**  link in the sidebar.
+
+## Build and push images
+
+> **Notes:**
+>
+> - Moving or renaming existing container registry repositories is not supported
+>   once you have pushed images because the images are signed, and the
+>   signature includes the repository name.
+> - To move or rename a repository with a container registry you will have to
+>   delete all existing images.
+
+If you visit the **Packages > Container Registry** link under your project's
+menu, you can see the explicit instructions to login to the Container Registry
+using your GitLab credentials.
+
+For example if the Registry's URL is `registry.example.com`, then you should be
+able to login with:
+
+```sh
+docker login registry.example.com
+```
+
+Building and publishing images should be a straightforward process. Just make
+sure that you are using the Registry URL with the namespace and project name
+that is hosted on GitLab:
+
+```sh
+docker build -t registry.example.com/group/project/image .
+docker push registry.example.com/group/project/image
+```
+
+Your image will be named after the following scheme:
+
+```text
+<registry URL>/<namespace>/<project>/<image>
+```
+
+GitLab supports up to three levels of image repository names.
+
+Following examples of image tags are valid:
+
+```text
+registry.example.com/group/project:some-tag
+registry.example.com/group/project/image:latest
+registry.example.com/group/project/my/image:rc1
+```
+
+## Use images from GitLab Container Registry
+
+To download and run a container from images hosted in GitLab Container Registry,
+use `docker run`:
+
+```sh
+docker run [options] registry.example.com/group/project/image [arguments]
+```
+
+For more information on running Docker containers, visit the
+[Docker documentation](https://docs.docker.com/engine/userguide/intro/).
+
+## Control Container Registry from within GitLab
+
+GitLab offers a simple Container Registry management panel. Go to your project
+and click **Packages > Container Registry** in the project menu.
+
+This view will show you all tags in your project and will easily allow you to
+delete them.
+
+## Build and push images using GitLab CI
+
+NOTE: **Note:**
+This feature requires GitLab 8.8 and GitLab Runner 1.2.
+
+Make sure that your GitLab Runner is configured to allow building Docker images by
+following the [Using Docker Build](../../../ci/docker/using_docker_build.md)
+and [Using the GitLab Container Registry documentation](../../../ci/docker/using_docker_build.md#using-the-gitlab-container-registry).
+Alternatively, you can [build images with Kaniko](../../../ci/docker/using_kaniko.md) if the Docker builds are not an option for you.
+
+## Using with private projects
+
+> Personal Access tokens were [introduced](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/11845) in GitLab 9.3.
+> Project Deploy Tokens were [introduced](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/17894) in GitLab 10.7
+
+If a project is private, credentials will need to be provided for authorization.
+There are two ways to do this:
+
+- By using a [personal access token](../../profile/personal_access_tokens.md).
+- By using a [deploy token](../../project/deploy_tokens/index.md).
+
+The minimal scope needed for both of them is `read_registry`.
+
+Example of using a token:
+
+```sh
+docker login registry.example.com -u <username> -p <token>
+```
+
+## Troubleshooting the GitLab Container Registry
+
+### Docker connection error
+
+A Docker connection error can occur when there are special characters in either the group,
+project or branch name. Special characters can include:
+
+- Leading underscore
+- Trailing hyphen/dash
+- Double hyphen/dash
+
+To get around this, you can [change the group path](../../group/index.md#changing-a-groups-path),
+[change the project path](../../project/settings/index.md#renaming-a-repository) or change the branch
+name.
+
+### Troubleshoot as a GitLab server admin
+
+Troubleshooting the GitLab Container Registry, most of the times, requires
+administration access to the GitLab server.
+
+[Read how to troubleshoot the Container Registry](../../../administration/packages/container_registry.md#troubleshooting).

+# GitLab Package Registry
+
+GitLab Packages allows organizations to utilize GitLab as a private repository
+for a variety of common package managers. Users are able to build and publish
+packages, which can be easily consumed as a dependency in downstream projects.
+
+The Packages feature allows GitLab to act as a repository for the following:
+
+| Software repository | Description | Available in GitLab version |
+| ------------------- | ----------- | --------------------------- |
+| [Container Registry](container_registry/index.md)   | The GitLab Container Registry enables every project in GitLab to have its own space to store [Docker](https://www.docker.com/) images. | 8.8+ |
+| [Dependency Proxy](dependency_proxy/index.md) **(PREMIUM)** | The GitLab Dependency Proxy sets up a local proxy for frequently used upstream images/packages. | 11.11+ |
+| [Maven Repository](maven_repository/index.md) **(PREMIUM)** | The GitLab Maven Repository enables every project in GitLab to have its own space to store [Maven](https://maven.apache.org/) packages. | 11.3+ |
+| [NPM Registry](npm_registry/index.md) **(PREMIUM)**  | The GitLab NPM Registry enables every project in GitLab to have its own space to store [NPM](https://www.npmjs.com/) packages. | 11.7+ |
+

+## Enabling the Maven Repository
+
+NOTE: **Note:**
+This option is available only if your GitLab administrator has

+1. Click on **Save changes** for the changes to take effect.
+
+You should then be able to see the **Packages** section on the left sidebar.
+Next, you must configure your project to authorize with the GitLab Maven

+
+## Authenticating to the GitLab Maven Repository
+
+If a project is private or you want to upload Maven artifacts to GitLab,

+          </property>
+        </httpHeaders>
+      </configuration>
+    </server>
+  </servers>
+</settings>
+```
+
+You should now be able to upload Maven artifacts to your project.
+
+### Authenticating with a CI job token
+
+If you're using Maven with GitLab CI/CD, a CI job token can be used instead
+of a personal access token.
+
+To authenticate with a CI job token, add a corresponding section to your
+[`settings.xml`](https://maven.apache.org/settings.html) file:
+
+```xml
+<settings>
+  <servers>
+    <server>
+      <id>gitlab-maven</id>
+      <configuration>
+        <httpHeaders>
+          <property>
+            <name>Job-Token</name>
+            <value>${env.CI_JOB_TOKEN}</value>
+          </property>
+        </httpHeaders>
+      </configuration>
+    </server>
+  </servers>
+</settings>
+```
+

+[how to create Maven packages using GitLab CI/CD](#creating-maven-packages-with-gitlab-cicd).
+
+## Configuring your project to use the GitLab Maven repository URL
+
+To download and upload packages from GitLab, you need a `repository` and
+`distributionManagement` section in your `pom.xml` file.
+
+Depending on your workflow and the amount of Maven packages you have, there are
+3 ways you can configure your project to use the GitLab endpoint for Maven packages:
+
+- **Project level**: Useful when you have few Maven packages which are not under
+  the same GitLab group.
+- **Group level**: Useful when you have many Maven packages under the same GitLab
+  group.
+- **Instance level**: Useful when you have many Maven packages under different
+  GitLab groups or on their own namespace.
+
+NOTE: **Note:**
+In all cases, you need a project specific URL for uploading a package in
+the `distributionManagement` section.
+
+### Project level Maven endpoint
+
+The example below shows how the relevant `repository` section of your `pom.xml`
+would look like:
+
+```xml
+<repositories>
+  <repository>
+    <id>gitlab-maven</id>
+    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>
+  </repository>
+</repositories>
+<distributionManagement>
+  <repository>
+    <id>gitlab-maven</id>
+    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>
+  </repository>
+  <snapshotRepository>
+    <id>gitlab-maven</id>
+    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>
+  </snapshotRepository>
+</distributionManagement>
+```
+
+The `id` must be the same with what you
+[defined in `settings.xml`](#authenticating-to-the-gitlab-maven-repository).
+
+Replace `PROJECT_ID` with your project ID which can be found on the home page
+of your project.
+
+If you have a self-hosted GitLab installation, replace `gitlab.com` with your
+domain name.
+
+NOTE: **Note:**
+For retrieving artifacts, you can use either the
+[URL encoded](../../../api/README.md#namespaced-path-encoding) path of the project
+(e.g., `group%2Fproject`) or the project's ID (e.g., `42`). However, only the
+project's ID can be used for uploading.
+
+### Group level Maven endpoint
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/8798) in GitLab Premium 11.7.
+
+If you rely on many packages, it might be inefficient to include the `repository` section
+with a unique URL for each package. Instead, you can use the group level endpoint for
+all your Maven packages stored within one GitLab group. Only packages you have access to
+will be available for download.
+
+The group level endpoint works with any package names, which means the you
+have the flexibility of naming compared to [instance level endpoint](#instance-level-maven-endpoint).
+However, GitLab will not guarantee the uniqueness of the package names within
+the group. You can have two projects with the same package name and package
+version. As a result, GitLab will serve whichever one is more recent.
+
+The example below shows how the relevant `repository` section of your `pom.xml`
+would look like. You still need a project specific URL for uploading a package in
+the `distributionManagement` section:
+
+```xml
+<repositories>
+  <repository>
+    <id>gitlab-maven</id>
+    <url>https://gitlab.com/api/v4/groups/my-group/-/packages/maven</url>
+  </repository>
+</repositories>
+<distributionManagement>
+  <repository>
+    <id>gitlab-maven</id>
+    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>
+  </repository>
+  <snapshotRepository>
+    <id>gitlab-maven</id>
+    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>
+  </snapshotRepository>
+</distributionManagement>
+```
+
+The `id` must be the same with what you
+[defined in `settings.xml`](#authenticating-to-the-gitlab-maven-repository).
+
+Replace `my-group` with your group name and `PROJECT_ID` with your project ID
+which can be found on the home page of your project.
+
+If you have a self-hosted GitLab installation, replace `gitlab.com` with your
+domain name.
+
+NOTE: **Note:**
+For retrieving artifacts, you can use either the
+[URL encoded](../../../api/README.md#namespaced-path-encoding) path of the group
+(e.g., `group%2Fsubgroup`) or the group's ID (e.g., `12`).
+
+### Instance level Maven endpoint
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/8274) in GitLab Premium 11.7.
+
+If you rely on many packages, it might be inefficient to include the `repository` section
+with a unique URL for each package. Instead, you can use the instance level endpoint for
+all maven packages stored in GitLab and the packages you have access to will be available
+for download.
+
+Note that **only packages that have the same path as the project** are exposed via
+the instance level endpoint.
+
+| Project | Package | Instance level endpoint available |
+| ------- | ------- | --------------------------------- |
+| `foo/bar`              | `foo/bar/1.0-SNAPSHOT`              | Yes |
+| `gitlab-org/gitlab-ce` | `foo/bar/1.0-SNAPSHOT`              | No  |
+| `gitlab-org/gitlab-ce` | `gitlab-org/gitlab-ce/1.0-SNAPSHOT` | Yes |
+
+The example below shows how the relevant `repository` section of your `pom.xml`
+would look like. You still need a project specific URL for uploading a package in
+the `distributionManagement` section:
+
+```xml
+<repositories>
+  <repository>
+    <id>gitlab-maven</id>
+    <url>https://gitlab.com/api/v4/packages/maven</url>
+  </repository>
+</repositories>
+<distributionManagement>
+  <repository>
+    <id>gitlab-maven</id>
+    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>
+  </repository>
+  <snapshotRepository>
+    <id>gitlab-maven</id>
+    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>
+  </snapshotRepository>
+</distributionManagement>
+```
+
+The `id` must be the same with what you
+[defined in `settings.xml`](#authenticating-to-the-gitlab-maven-repository).
+
+Replace `PROJECT_ID` with your project ID which can be found on the home page
+of your project.
+
+If you have a self-hosted GitLab installation, replace `gitlab.com` with your
+domain name.
+
+NOTE: **Note:**
+For retrieving artifacts, you can use either the
+[URL encoded](../../../api/README.md#namespaced-path-encoding) path of the project
+(e.g., `group%2Fproject`) or the project's ID (e.g., `42`). However, only the
+project's ID can be used for uploading.
+
+## Uploading packages
+
+Once you have set up the [authentication](#authenticating-to-the-gitlab-maven-repository)
+and [configuration](#configuring-your-project-to-use-the-gitlab-maven-repository-url),
+test to upload a Maven artifact from a project of yours:
+
+```sh
+mvn deploy
+```
+
+You can then navigate to your project's **Packages** page and see the uploaded
+artifacts or even delete them.
+
+## Creating Maven packages with GitLab CI/CD
+
+Once you have your repository configured to use the GitLab Maven Repository,
+you can configure GitLab CI/CD to build new packages automatically. The example below
+shows how to create a new package each time the `master` branch is updated:
+
+1. Create a `ci_settings.xml` file that will serve as Maven's `settings.xml` file.
+   Add the server section with the same id you defined in your `pom.xml` file.
+   For example, in our case it's `gitlab-maven`:
+
+   ```xml
+   <settings xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+     xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd">
+     <servers>
+       <server>
+         <id>gitlab-maven</id>
+         <configuration>
+           <httpHeaders>
+             <property>
+               <name>Job-Token</name>
+               <value>${env.CI_JOB_TOKEN}</value>
+             </property>
+           </httpHeaders>
+         </configuration>
+       </server>
+     </servers>
+   </settings>
+   ```
+
+1. Make sure your `pom.xml` file includes the following:
+
+   ```xml
+   <repositories>
+     <repository>
+       <id>gitlab-maven</id>
+       <url>https://gitlab.com/api/v4/projects/${env.CI_PROJECT_ID}/packages/maven</url>
+     </repository>
+   </repositories>
+   <distributionManagement>
+     <repository>
+       <id>gitlab-maven</id>
+       <url>https://gitlab.com/api/v4/projects/${env.CI_PROJECT_ID}/packages/maven</url>
+     </repository>
+     <snapshotRepository>
+       <id>gitlab-maven</id>
+       <url>https://gitlab.com/api/v4/projects/${env.CI_PROJECT_ID}/packages/maven</url>
+     </snapshotRepository>
+   </distributionManagement>
+   ```
+
+   TIP: **Tip:**
+   You can either let Maven utilize the CI environment variables or hardcode your project's ID.
+
+1. Add a `deploy` job to your `.gitlab-ci.yml` file:
+
+   ```yaml
+   deploy:
+     image: maven:3.3.9-jdk-8
+     script:
+       - 'mvn deploy -s ci_settings.xml'
+     only:
+       - master
+   ```
+
+1. Push those files to your repository.
+
+The next time the `deploy` job runs, it will copy `ci_settings.xml` to the
+user's home location (in this case the user is `root` since it runs in a
+Docker container), and Maven will utilize the configured CI
+[environment variables](../../../ci/variables/README.md#predefined-environment-variables).

+# GitLab NPM Registry **(PREMIUM)**
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/5934) in [GitLab Premium](https://about.gitlab.com/pricing/) 11.7.
+
+With the GitLab NPM Registry, every
+project can have its own space to store NPM packages.
+
+![GitLab NPM Registry](img/npm_package_view.png)
+
+NOTE: **Note:**
+Only [scoped](https://docs.npmjs.com/misc/scope) packages are supported.
+
+## Enabling the NPM Registry
+
+NOTE: **Note:**
+This option is available only if your GitLab administrator has
+[enabled support for the NPM registry](../../../administration/packages/index.md).**(PREMIUM ONLY)**
+
+After the NPM registry is enabled, it will be available for all new projects
+by default. To enable it for existing projects, or if you want to disable it:
+
+1. Navigate to your project's **Settings > General > Permissions**.
+1. Find the Packages feature and enable or disable it.
+1. Click on **Save changes** for the changes to take effect.
+
+You should then be able to see the **Packages** section on the left sidebar.
+
+Before proceeding to authenticating with the GitLab NPM Registry, you should
+get familiar with the package naming convention.
+
+## Package naming convention
+
+**Packages must be scoped in the root namespace of the project**. The package
+name may be anything but it is preferred that the project name be used unless
+it is not possible due to a naming collision. For example:
+
+| Project                | Package                 | Supported |
+| ---------------------- | ----------------------- | --------- |
+| `foo/bar`              | `@foo/bar`              | Yes       |
+| `foo/bar/baz`          | `@foo/baz`              | Yes       |
+| `foo/bar/buz`          | `@foo/anything`         | Yes       |
+| `gitlab-org/gitlab-ce` | `@gitlab-org/gitlab-ce` | Yes       |
+| `gitlab-org/gitlab-ce` | `@foo/bar`              | No        |
+
+Now, you can configure your project to authenticate with the GitLab NPM
+Registry.
+
+## Authenticating to the GitLab NPM Registry
+
+If a project is private or you want to upload an NPM package to GitLab,
+credentials will need to be provided for authentication. Support is available for [OAuth tokens](../../../api/oauth2.md#resource-owner-password-credentials-flow) or [personal access tokens](../../profile/personal_access_tokens.md).
+
+CAUTION: **2FA is only supported with personal access tokens:**
+If you have 2FA enabled, you need to use a [personal access token](../../profile/personal_access_tokens.md) with OAuth headers. Standard OAuth tokens won't be able to authenticate to the GitLab NPM Registry.
+
+### Authenticating with an OAuth token
+
+To authenticate with an [OAuth token](../../../api/oauth2.md#resource-owner-password-credentials-flow)
+or [personal access token](../../profile/personal_access_tokens.md), add a corresponding section to your `.npmrc` file:
+
+```ini
+; Set URL for your scoped packages.
+; For example package with name `@foo/bar` will use this URL for download
+@foo:registry=https://gitlab.com/api/v4/packages/npm/
+
+; Add the token for the scoped packages URL. This will allow you to download
+; `@foo/` packages from private projects.
+//gitlab.com/api/v4/packages/npm/:_authToken=<your_token>
+
+; Add token for uploading to the registry. Replace <your_project_id>
+; with the project you want your package to be uploaded to.
+//gitlab.com/api/v4/projects/<your_project_id>/packages/npm/:_authToken=<your_token>
+```
+
+Replace `<your_project_id>` with your project ID which can be found on the home page
+of your project and `<your_token>` with your OAuth or personal access token.
+
+If you have a self-hosted GitLab installation, replace `gitlab.com` with your
+domain name.
+
+You should now be able to download and upload NPM packages to your project.
+
+NOTE: **Note:**
+If you encounter an error message with [Yarn](https://yarnpkg.com/en/), see the
+[troubleshooting section](#troubleshooting).
+
+## Uploading packages
+
+Before you will be able to upload a package, you need to specify the registry
+for NPM. To do this, add the following section to the bottom of `package.json`:
+
+```json
+  "publishConfig": {
+    "@foo:registry":"https://gitlab.com/api/v4/projects/<your_project_id>/packages/npm/"
+  }
+```
+
+Replace `<your_project_id>` with your project ID, which can be found on the home
+page of your project, and replace `@foo` with your own scope.
+
+If you have a self-hosted GitLab installation, replace `gitlab.com` with your
+domain name.
+
+Once you have enabled it and set up [authentication](#authenticating-to-the-gitlab-npm-registry),
+you can upload an NPM package to your project:
+
+```sh
+npm publish
+```
+
+You can then navigate to your project's **Packages** page and see the uploaded
+packages or even delete them.
+
+If you attempt to publish a package with a name that already exists within
+a given scope, you will receive a `403 Forbidden!` error.
+
+## Uploading a package with the same version twice
+
+If you upload a package with a same name and version twice, GitLab will show
+both packages in the UI, but the GitLab NPM Registry will expose the most recent
+one as it supports only one package per version for `npm install`.
+
+## Troubleshooting
+
+### Error running yarn with NPM registry
+
+If you are using [yarn](https://yarnpkg.com/en/) with the NPM registry, you may get
+an error message like:
+
+```sh
+yarn install v1.15.2
+warning package.json: No license field
+info No lockfile found.
+warning XXX: No license field
+[1/4] 🔍  Resolving packages...
+[2/4] 🚚  Fetching packages...
+error An unexpected error occurred: "https://gitlab.com/api/v4/projects/XXX/packages/npm/XXX/XXX/-/XXX/XXX-X.X.X.tgz: Request failed \"404 Not Found\"".
+info If you think this is a bug, please open a bug report with the information provided in "/Users/XXX/gitlab-migration/module-util/yarn-error.log".
+info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command
+```
+
+In this case, try adding this to your `.npmrc` file (and replace `<your_oauth_token>`
+with your with your OAuth or personal access token):
+
+```text
+//gitlab.com/api/v4/projects/:_authToken=<your_oauth_token>
+```

-# GitLab Container Registry
+---
+redirect_to: '../packages/container_registry/index.md'
+---
 
-> - [Introduced][ce-4040] in GitLab 8.8.
-> - Docker Registry manifest `v1` support was added in GitLab 8.9 to support Docker
->   versions earlier than 1.10.
-> - Starting from GitLab 8.12, if you have 2FA enabled in your account, you need
->   to pass a [personal access token][pat] instead of your password in order to
->   login to GitLab's Container Registry.
-> - Multiple level image names support was added in GitLab 9.1.
-
-With the Docker Container Registry integrated into GitLab, every project can
-have its own space to store its Docker images.
-
-This document is the user guide. To learn how to enable GitLab Container
-Registry across your GitLab instance, visit the
-[administrator documentation](../../administration/container_registry.md).
-
-You can read more about Docker Registry at <https://docs.docker.com/registry/introduction/>.
-
-## Enable the Container Registry for your project
-
-If you cannot find the **Packages > Container Registry** entry under your
-project's sidebar, it is not enabled in your GitLab instance. Ask your
-administrator to enable GitLab Container Registry following the
-[administration documentation](../../administration/container_registry.md).
-
-If you are using GitLab.com, this is enabled by default so you can start using
-the Registry immediately. Currently there is a soft (10GB) size restriction for
-registry on GitLab.com, as part of the [repository size limit](repository/index.md).
-
-Once enabled for your GitLab instance, to enable Container Registry for your
-project:
-
-1. Go to your project's **Settings > General** page.
-1. Expand the **Visibility, project features, permissions** section
-   and enable the **Container Registry** feature on your project. For new
-   projects this might be enabled by default. For existing projects
-   (prior GitLab 8.8), you will have to explicitly enable it.
-1. Press **Save changes** for the changes to take effect. You should now be able
-   to see the **Packages > Container Registry**  link in the sidebar.
-
-## Build and push images
-
-> **Notes:**
->
-> - Moving or renaming existing container registry repositories is not supported
->   once you have pushed images because the images are signed, and the
->   signature includes the repository name.
-> - To move or rename a repository with a container registry you will have to
->   delete all existing images.
-
-If you visit the **Packages > Container Registry** link under your project's
-menu, you can see the explicit instructions to login to the Container Registry
-using your GitLab credentials.
-
-For example if the Registry's URL is `registry.example.com`, then you should be
-able to login with:
-
-```sh
-docker login registry.example.com
-```
-
-Building and publishing images should be a straightforward process. Just make
-sure that you are using the Registry URL with the namespace and project name
-that is hosted on GitLab:
-
-```sh
-docker build -t registry.example.com/group/project/image .
-docker push registry.example.com/group/project/image
-```
-
-Your image will be named after the following scheme:
-
-```text
-<registry URL>/<namespace>/<project>/<image>
-```
-
-GitLab supports up to three levels of image repository names.
-
-Following examples of image tags are valid:
-
-```text
-registry.example.com/group/project:some-tag
-registry.example.com/group/project/image:latest
-registry.example.com/group/project/my/image:rc1
-```
-
-## Use images from GitLab Container Registry
-
-To download and run a container from images hosted in GitLab Container Registry,
-use `docker run`:
-
-```sh
-docker run [options] registry.example.com/group/project/image [arguments]
-```
-
-For more information on running Docker containers, visit the
-[Docker documentation][docker-docs].
-
-## Control Container Registry from within GitLab
-
-GitLab offers a simple Container Registry management panel. Go to your project
-and click **Packages > Container Registry** in the project menu.
-
-This view will show you all tags in your project and will easily allow you to
-delete them.
-
-## Build and push images using GitLab CI
-
-> **Note:**
-This feature requires GitLab 8.8 and GitLab Runner 1.2.
-
-Make sure that your GitLab Runner is configured to allow building Docker images by
-following the [Using Docker Build](../../ci/docker/using_docker_build.md)
-and [Using the GitLab Container Registry documentation](../../ci/docker/using_docker_build.md#using-the-gitlab-container-registry).
-Alternatively, you can [build images with Kaniko](../../ci/docker/using_kaniko.md) if the Docker builds are not an option for you.
-
-## Using with private projects
-
-> Personal Access tokens were [introduced][ce-11845] in GitLab 9.3.
-> Project Deploy Tokens were [introduced][ce-17894] in GitLab 10.7
-
-If a project is private, credentials will need to be provided for authorization.
-There are two ways to do this:
-
-- By using a [personal access token](../profile/personal_access_tokens.md).
-- By using a [deploy token](../project/deploy_tokens/index.md).
-
-The minimal scope needed for both of them is `read_registry`.
-
-Example of using a token:
-
-```sh
-docker login registry.example.com -u <username> -p <token>
-```
-
-## Troubleshooting the GitLab Container Registry
-
-### Basic Troubleshooting
-
-1. Check to make sure that the system clock on your Docker client and GitLab server have
-   been synchronized (e.g. via NTP).
-
-1. If you are using an S3-backed Registry, double check that the IAM
-   permissions and the S3 credentials (including region) are correct. See [the
-   sample IAM policy](https://docs.docker.com/registry/storage-drivers/s3/)
-   for more details.
-
-1. Check the Registry logs (e.g. `/var/log/gitlab/registry/current`) and the GitLab production logs
-   for errors (e.g. `/var/log/gitlab/gitlab-rails/production.log`). You may be able to find clues
-   there.
-
-#### Enable the registry debug server
-
-The optional debug server can be enabled by setting the registry debug address
-in your `gitlab.rb` configuration.
-
-```ruby
-registry['debug_addr'] = "localhost:5001"
-```
-
-After adding the setting, [reconfigure] GitLab to apply the change.
-
-Use curl to request debug output from the debug server:
-
-```bash
-curl localhost:5001/debug/health
-curl localhost:5001/debug/vars
-```
-
-#### Docker connection error
-
-A Docker connection error can occur when there are special characters in either the group,
-project or branch name. Special characters can include:
-
-- Leading underscore
-- Trailing hyphen/dash
-- Double hyphen/dash
-
-To get around this, you can [change the group path](../group/index.md#changing-a-groups-path),
-[change the project path](../project/settings/index.md#renaming-a-repository) or chanage the branch
-name.
-
-### Advanced Troubleshooting
-
-NOTE: **Note:**
-The following section is only recommended for experts.
-
-Sometimes it's not obvious what is wrong, and you may need to dive deeper into
-the communication between the Docker client and the Registry to find out
-what's wrong. We will use a concrete example in the past to illustrate how to
-diagnose a problem with the S3 setup.
-
-#### Unexpected 403 error during push
-
-A user attempted to enable an S3-backed Registry. The `docker login` step went
-fine. However, when pushing an image, the output showed:
-
-```text
-The push refers to a repository [s3-testing.myregistry.com:4567/root/docker-test/docker-image]
-dc5e59c14160: Pushing [==================================================>] 14.85 kB

-228950524c88: Pushing 2.048 kB
-6a8ecde4cc03: Pushing [==>                                                ] 9.901 MB/205.7 MB

-19429b698a22: Waiting
-9436069b92a3: Waiting
-error parsing HTTP 403 response body: unexpected end of JSON input: ""
-```
-
-This error is ambiguous, as it's not clear whether the 403 is coming from the
-GitLab Rails application, the Docker Registry, or something else. In this
-case, since we know that since the login succeeded, we probably need to look
-at the communication between the client and the Registry.
-
-The REST API between the Docker client and Registry is [described
-here](https://docs.docker.com/registry/spec/api/). Normally, one would just
-use Wireshark or tcpdump to capture the traffic and see where things went
-wrong. However, since all communications between Docker clients and servers
-are done over HTTPS, it's a bit difficult to decrypt the traffic quickly even
-if you know the private key. What can we do instead?
-
-One way would be to disable HTTPS by setting up an [insecure
-Registry](https://docs.docker.com/registry/insecure/). This could introduce a
-security hole and is only recommended for local testing. If you have a
-production system and can't or don't want to do this, there is another way:
-use mitmproxy, which stands for Man-in-the-Middle Proxy.
-
-#### mitmproxy
-
-[mitmproxy](https://mitmproxy.org/) allows you to place a proxy between your
-client and server to inspect all traffic. One wrinkle is that your system
-needs to trust the mitmproxy SSL certificates for this to work.
-
-The following installation instructions assume you are running Ubuntu:
-
-1. [Install mitmproxy](https://docs.mitmproxy.org/stable/overview-installation/).
-1. Run `mitmproxy --port 9000` to generate its certificates.
-   Enter <kbd>CTRL</kbd>-<kbd>C</kbd> to quit.
-1. Install the certificate from `~/.mitmproxy` to your system:
-
-   ```sh
-   sudo cp ~/.mitmproxy/mitmproxy-ca-cert.pem /usr/local/share/ca-certificates/mitmproxy-ca-cert.crt
-   sudo update-ca-certificates
-   ```
-
-If successful, the output should indicate that a certificate was added:
-
-```sh
-Updating certificates in /etc/ssl/certs... 1 added, 0 removed; done.
-Running hooks in /etc/ca-certificates/update.d....done.
-```
-
-To verify that the certificates are properly installed, run:
-
-```sh
-mitmproxy --port 9000
-```
-
-This will run mitmproxy on port `9000`. In another window, run:
-
-```sh
-curl --proxy http://localhost:9000 https://httpbin.org/status/200
-```
-
-If everything is set up correctly, you will see information on the mitmproxy window and
-no errors from the curl commands.
-
-#### Running the Docker daemon with a proxy
-
-For Docker to connect through a proxy, you must start the Docker daemon with the
-proper environment variables. The easiest way is to shutdown Docker (e.g. `sudo initctl stop docker`)
-and then run Docker by hand. As root, run:
-
-```sh
-export HTTP_PROXY="http://localhost:9000"
-export HTTPS_PROXY="https://localhost:9000"
-docker daemon --debug
-```
-
-This will launch the Docker daemon and proxy all connections through mitmproxy.
-
-#### Running the Docker client
-
-Now that we have mitmproxy and Docker running, we can attempt to login and push
-a container image. You may need to run as root to do this. For example:
-
-```sh
-docker login s3-testing.myregistry.com:4567
-docker push s3-testing.myregistry.com:4567/root/docker-test/docker-image
-```
-
-In the example above, we see the following trace on the mitmproxy window:
-
-![mitmproxy output from Docker](img/mitmproxy-docker.png)
-
-The above image shows:
-
-- The initial PUT requests went through fine with a 201 status code.
-- The 201 redirected the client to the S3 bucket.
-- The HEAD request to the AWS bucket reported a 403 Unauthorized.
-
-What does this mean? This strongly suggests that the S3 user does not have the right
-[permissions to perform a HEAD request](http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectHEAD.html).
-The solution: check the [IAM permissions again](https://docs.docker.com/registry/storage-drivers/s3/).
-Once the right permissions were set, the error will go away.

-
-With the GitLab [Maven](https://maven.apache.org) Repository, every
-project can have its own space to store its Maven artifacts.
-
-![GitLab Maven Repository](img/maven_package_view.png)
-
-## Enabling the Maven Repository
-
-NOTE: **Note:**
-This option is available only if your GitLab administrator has
-[enabled support for the Maven repository](../../../administration/packages.md).**(PREMIUM ONLY)**
-
-After the Packages feature is enabled, the Maven Repository will be available for
-all new projects by default. To enable it for existing projects, or if you want
-to disable it:
-
-1. Navigate to your project's **Settings > General > Permissions**.
-1. Find the Packages feature and enable or disable it.
-1. Click on **Save changes** for the changes to take effect.
-
-You should then be able to see the **Packages** section on the left sidebar.
-Next, you must configure your project to authorize with the GitLab Maven
-repository.
-
-## Authenticating to the GitLab Maven Repository
-
-If a project is private or you want to upload Maven artifacts to GitLab,
-credentials will need to be provided for authorization. Support is available for
-[personal access tokens](#authenticating-with-a-personal-access-token) and
-[CI job tokens](#authenticating-with-a-ci-job-token) only.
-[Deploy tokens](../deploy_tokens/index.md) and regular username/password
-credentials do not work.
-
-### Authenticating with a personal access token
-
-To authenticate with a [personal access token](../../profile/personal_access_tokens.md),
-add a corresponding section to your
-[`settings.xml`](https://maven.apache.org/settings.html) file:
-
-```xml
-<settings>
-  <servers>
-    <server>
-      <id>gitlab-maven</id>
-      <configuration>
-        <httpHeaders>
-          <property>
-            <name>Private-Token</name>
-            <value>REPLACE_WITH_YOUR_PERSONAL_ACCESS_TOKEN</value>
-          </property>
-        </httpHeaders>
-      </configuration>
-    </server>
-  </servers>
-</settings>
-```
-
-You should now be able to upload Maven artifacts to your project.
-
-### Authenticating with a CI job token
-
-If you're using Maven with GitLab CI/CD, a CI job token can be used instead
-of a personal access token.
-
-To authenticate with a CI job token, add a corresponding section to your
-[`settings.xml`](https://maven.apache.org/settings.html) file:
-
-```xml
-<settings>
-  <servers>
-    <server>
-      <id>gitlab-maven</id>
-      <configuration>
-        <httpHeaders>
-          <property>
-            <name>Job-Token</name>
-            <value>${env.CI_JOB_TOKEN}</value>
-          </property>
-        </httpHeaders>
-      </configuration>
-    </server>
-  </servers>
-</settings>
-```
-
-You can read more on
-[how to create Maven packages using GitLab CI/CD](#creating-maven-packages-with-gitlab-cicd).
-
-## Configuring your project to use the GitLab Maven repository URL
-
-To download and upload packages from GitLab, you need a `repository` and
-`distributionManagement` section in your `pom.xml` file.
-
-Depending on your workflow and the amount of Maven packages you have, there are
-3 ways you can configure your project to use the GitLab endpoint for Maven packages:
-
-- **Project level**: Useful when you have few Maven packages which are not under
-  the same GitLab group.
-- **Group level**: Useful when you have many Maven packages under the same GitLab
-  group.
-- **Instance level**: Useful when you have many Maven packages under different
-  GitLab groups or on their own namespace.
-
-NOTE: **Note:**
-In all cases, you need a project specific URL for uploading a package in
-the `distributionManagement` section.
-
-### Project level Maven endpoint
-
-The example below shows how the relevant `repository` section of your `pom.xml`
-would look like:
-
-```xml
-<repositories>
-  <repository>
-    <id>gitlab-maven</id>
-    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>
-  </repository>
-</repositories>
-<distributionManagement>
-  <repository>
-    <id>gitlab-maven</id>
-    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>
-  </repository>
-  <snapshotRepository>
-    <id>gitlab-maven</id>
-    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>
-  </snapshotRepository>
-</distributionManagement>
-```
-
-The `id` must be the same with what you
-[defined in `settings.xml`](#authenticating-to-the-gitlab-maven-repository).
-
-Replace `PROJECT_ID` with your project ID which can be found on the home page
-of your project.
-
-If you have a self-hosted GitLab installation, replace `gitlab.com` with your
-domain name.
-
-NOTE: **Note:**
-For retrieving artifacts, you can use either the
-[URL encoded](../../../api/README.md#namespaced-path-encoding) path of the project
-(e.g., `group%2Fproject`) or the project's ID (e.g., `42`). However, only the
-project's ID can be used for uploading.
-
-### Group level Maven endpoint
-
-> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/8798) in GitLab Premium 11.7.
-
-If you rely on many packages, it might be inefficient to include the `repository` section
-with a unique URL for each package. Instead, you can use the group level endpoint for
-all your Maven packages stored within one GitLab group. Only packages you have access to
-will be available for download.
-
-The group level endpoint works with any package names, which means the you
-have the flexibility of naming compared to [instance level endpoint](#instance-level-maven-endpoint).
-However, GitLab will not guarantee the uniqueness of the package names within
-the group. You can have two projects with the same package name and package
-version. As a result, GitLab will serve whichever one is more recent.
-
-The example below shows how the relevant `repository` section of your `pom.xml`
-would look like. You still need a project specific URL for uploading a package in
-the `distributionManagement` section:
-
-```xml
-<repositories>
-  <repository>
-    <id>gitlab-maven</id>
-    <url>https://gitlab.com/api/v4/groups/my-group/-/packages/maven</url>
-  </repository>
-</repositories>
-<distributionManagement>
-  <repository>
-    <id>gitlab-maven</id>
-    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>

-    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>
-  </snapshotRepository>
-</distributionManagement>
-```
-
-The `id` must be the same with what you
-[defined in `settings.xml`](#authenticating-to-the-gitlab-maven-repository).
-
-Replace `my-group` with your group name and `PROJECT_ID` with your project ID
-which can be found on the home page of your project.
-
-If you have a self-hosted GitLab installation, replace `gitlab.com` with your
-domain name.
-
-NOTE: **Note:**
-For retrieving artifacts, you can use either the
-[URL encoded](../../../api/README.md#namespaced-path-encoding) path of the group
-(e.g., `group%2Fsubgroup`) or the group's ID (e.g., `12`).
-
-### Instance level Maven endpoint
-
-> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/8274) in GitLab Premium 11.7.
-
-If you rely on many packages, it might be inefficient to include the `repository` section
-with a unique URL for each package. Instead, you can use the instance level endpoint for
-all maven packages stored in GitLab and the packages you have access to will be available
-for download.
-
-Note that **only packages that have the same path as the project** are exposed via
-the instance level endpoint.
-
-| Project | Package | Instance level endpoint available |
-| ------- | ------- | --------------------------------- |
-| `foo/bar`              | `foo/bar/1.0-SNAPSHOT`              | Yes |
-| `gitlab-org/gitlab-ce` | `foo/bar/1.0-SNAPSHOT`              | No  |
-| `gitlab-org/gitlab-ce` | `gitlab-org/gitlab-ce/1.0-SNAPSHOT` | Yes |
-
-The example below shows how the relevant `repository` section of your `pom.xml`
-would look like. You still need a project specific URL for uploading a package in
-the `distributionManagement` section:
-
-```xml
-<repositories>
-  <repository>
-    <id>gitlab-maven</id>
-    <url>https://gitlab.com/api/v4/packages/maven</url>
-  </repository>
-</repositories>
-<distributionManagement>
-  <repository>
-    <id>gitlab-maven</id>
-    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>
-  </repository>
-  <snapshotRepository>
-    <id>gitlab-maven</id>
-    <url>https://gitlab.com/api/v4/projects/PROJECT_ID/packages/maven</url>
-  </snapshotRepository>
-</distributionManagement>
-```
-
-The `id` must be the same with what you
-[defined in `settings.xml`](#authenticating-to-the-gitlab-maven-repository).
-
-Replace `PROJECT_ID` with your project ID which can be found on the home page
-of your project.
-
-If you have a self-hosted GitLab installation, replace `gitlab.com` with your
-domain name.
-
-NOTE: **Note:**
-For retrieving artifacts, you can use either the
-[URL encoded](../../../api/README.md#namespaced-path-encoding) path of the project
-(e.g., `group%2Fproject`) or the project's ID (e.g., `42`). However, only the
-project's ID can be used for uploading.
-
-## Uploading packages
-
-Once you have set up the [authentication](#authenticating-to-the-gitlab-maven-repository)
-and [configuration](#configuring-your-project-to-use-the-gitlab-maven-repository-url),
-test to upload a Maven artifact from a project of yours:
-
-```sh
-mvn deploy
-```
-
-You can then navigate to your project's **Packages** page and see the uploaded
-artifacts or even delete them.
-
-## Creating Maven packages with GitLab CI/CD
-
-Once you have your repository configured to use the GitLab Maven Repository,
-you can configure GitLab CI/CD to build new packages automatically. The example below
-shows how to create a new package each time the `master` branch is updated:
-
-1. Create a `ci_settings.xml` file that will serve as Maven's `settings.xml` file.
-   Add the server section with the same id you defined in your `pom.xml` file.
-   For example, in our case it's `gitlab-maven`:
-
-   ```xml
-   <settings xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
-     xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd">
-     <servers>
-       <server>
-         <id>gitlab-maven</id>
-         <configuration>
-           <httpHeaders>
-             <property>
-               <name>Job-Token</name>
-               <value>${env.CI_JOB_TOKEN}</value>
-             </property>
-           </httpHeaders>
-         </configuration>
-       </server>
-     </servers>
-   </settings>
-   ```
-
-1. Make sure your `pom.xml` file includes the following:
-
-   ```xml
-   <repositories>
-     <repository>
-       <id>gitlab-maven</id>
-       <url>https://gitlab.com/api/v4/projects/${env.CI_PROJECT_ID}/packages/maven</url>
-     </repository>
-   </repositories>
-   <distributionManagement>
-     <repository>
-       <id>gitlab-maven</id>
-       <url>https://gitlab.com/api/v4/projects/${env.CI_PROJECT_ID}/packages/maven</url>
-     </repository>
-     <snapshotRepository>
-       <id>gitlab-maven</id>
-       <url>https://gitlab.com/api/v4/projects/${env.CI_PROJECT_ID}/packages/maven</url>
-     </snapshotRepository>
-   </distributionManagement>
-   ```
-
-   TIP: **Tip:**
-   You can either let Maven utilize the CI environment variables or hardcode your project's ID.
-
-1. Add a `deploy` job to your `.gitlab-ci.yml` file:
-
-   ```yaml
-   deploy:
-     image: maven:3.3.9-jdk-8
-     script:
-       - 'mvn deploy -s ci_settings.xml'
-     only:
-       - master
-   ```
-
-1. Push those files to your repository.
-
-The next time the `deploy` job runs, it will copy `ci_settings.xml` to the
-user's home location (in this case the user is `root` since it runs in a
-Docker container), and Maven will utilize the configured CI
-[environment variables](../../../ci/variables/README.md#predefined-environment-variables).

-# GitLab NPM Registry **(PREMIUM)**
+---
+redirect_to: '../../packages/npm_registry/index.md'
+---
 
-> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/5934) in [GitLab Premium](https://about.gitlab.com/pricing/) 11.7.
-
-With the GitLab NPM Registry, every
-project can have its own space to store NPM packages.
-
-![GitLab NPM Registry](img/npm_package_view.png)
-
-NOTE: **Note:**
-Only [scoped](https://docs.npmjs.com/misc/scope) packages are supported.
-
-## Enabling the NPM Registry
-
-NOTE: **Note:**
-This option is available only if your GitLab administrator has
-[enabled support for the NPM registry](../../../administration/packages.md).**(PREMIUM ONLY)**
-
-After the NPM registry is enabled, it will be available for all new projects
-by default. To enable it for existing projects, or if you want to disable it:
-
-1. Navigate to your project's **Settings > General > Permissions**.
-1. Find the Packages feature and enable or disable it.
-1. Click on **Save changes** for the changes to take effect.
-
-You should then be able to see the **Packages** section on the left sidebar.
-
-Before proceeding to authenticating with the GitLab NPM Registry, you should
-get familiar with the package naming convention.
-
-## Package naming convention
-
-**Packages must be scoped in the root namespace of the project**. The package
-name may be anything but it is preferred that the project name be used unless
-it is not possible due to a naming collision. For example:
-
-| Project                | Package                 | Supported |
-| ---------------------- | ----------------------- | --------- |
-| `foo/bar`              | `@foo/bar`              | Yes       |
-| `foo/bar/baz`          | `@foo/baz`              | Yes       |
-| `foo/bar/buz`          | `@foo/anything`         | Yes       |
-| `gitlab-org/gitlab-ce` | `@gitlab-org/gitlab-ce` | Yes       |
-| `gitlab-org/gitlab-ce` | `@foo/bar`              | No        |
-
-Now, you can configure your project to authenticate with the GitLab NPM
-Registry.
-
-## Authenticating to the GitLab NPM Registry
-
-If a project is private or you want to upload an NPM package to GitLab,
-credentials will need to be provided for authentication. Support is available for [OAuth tokens](../../../api/oauth2.md#resource-owner-password-credentials-flow) or [personal access tokens](../../profile/personal_access_tokens.md).
-
-CAUTION: **2FA is only supported with personal access tokens:**
-If you have 2FA enabled, you need to use a [personal access token](../../profile/personal_access_tokens.md) with OAuth headers. Standard OAuth tokens won't be able to authenticate to the GitLab NPM Registry.
-
-### Authenticating with an OAuth token
-
-To authenticate with an [OAuth token](../../../api/oauth2.md#resource-owner-password-credentials-flow)
-or [personal access token](../../profile/personal_access_tokens.md), add a corresponding section to your `.npmrc` file:
-
-```ini
-; Set URL for your scoped packages.
-; For example package with name `@foo/bar` will use this URL for download
-@foo:registry=https://gitlab.com/api/v4/packages/npm/
-
-; Add the token for the scoped packages URL. This will allow you to download
-; `@foo/` packages from private projects.
-//gitlab.com/api/v4/packages/npm/:_authToken=<your_token>
-
-; Add token for uploading to the registry. Replace <your_project_id>
-; with the project you want your package to be uploaded to.
-//gitlab.com/api/v4/projects/<your_project_id>/packages/npm/:_authToken=<your_token>
-```
-
-Replace `<your_project_id>` with your project ID which can be found on the home page
-of your project and `<your_token>` with your OAuth or personal access token.
-
-If you have a self-hosted GitLab installation, replace `gitlab.com` with your
-domain name.
-
-You should now be able to download and upload NPM packages to your project.
-
-NOTE: **Note:**
-If you encounter an error message with [Yarn](https://yarnpkg.com/en/), see the
-[troubleshooting section](#troubleshooting).
-
-## Uploading packages
-
-Before you will be able to upload a package, you need to specify the registry
-for NPM. To do this, add the following section to the bottom of `package.json`:
-
-```json
-  "publishConfig": {
-    "@foo:registry":"https://gitlab.com/api/v4/projects/<your_project_id>/packages/npm/"
-  }
-```
-
-Replace `<your_project_id>` with your project ID, which can be found on the home
-page of your project, and replace `@foo` with your own scope.
-
-If you have a self-hosted GitLab installation, replace `gitlab.com` with your
-domain name.
-
-Once you have enabled it and set up [authentication](#authenticating-to-the-gitlab-npm-registry),
-you can upload an NPM package to your project:
-
-```sh
-npm publish
-```
-
-You can then navigate to your project's **Packages** page and see the uploaded
-packages or even delete them.
-
-If you attempt to publish a package with a name that already exists within
-a given scope, you will receive a `403 Forbidden!` error.
-
-## Uploading a package with the same version twice
-
-If you upload a package with a same name and version twice, GitLab will show
-both packages in the UI, but the GitLab NPM Registry will expose the most recent
-one as it supports only one package per version for `npm install`.
-
-## Troubleshooting
-
-### Error running yarn with NPM registry
-
-If you are using [yarn](https://yarnpkg.com/en/) with the NPM registry, you may get
-an error message like:
-
-```sh
-yarn install v1.15.2
-warning package.json: No license field
-info No lockfile found.
-warning XXX: No license field
-[1/4] 🔍  Resolving packages...
-[2/4] 🚚  Fetching packages...
-error An unexpected error occurred: "https://gitlab.com/api/v4/projects/XXX/packages/npm/XXX/XXX/-/XXX/XXX-X.X.X.tgz: Request failed \"404 Not Found\"".
-info If you think this is a bug, please open a bug report with the information provided in "/Users/XXX/gitlab-migration/module-util/yarn-error.log".
-info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command
-```
-
-In this case, try adding this to your `.npmrc` file (and replace `<your_oauth_token>`
-with your with your OAuth or personal access token):
-
-```text
-//gitlab.com/api/v4/projects/:_authToken=<your_oauth_token>
-```
