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.

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"] -``` - -Additional information about this: [issue 18239][ce-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.

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.

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.

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.

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: + + + +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. diff --git a/doc/administration/packages/dependency_proxy.md b/doc/administration/packages/dependency_proxy.md new file mode 100644 index 00000000000..967ba2592c3 --- /dev/null +++ b/doc/administration/packages/dependency_proxy.md @@ -0,0 +1,148 @@ +# 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.
