Elasticsearch requires additional resources to those documented in the

-Memory, CPU, and storage resource amounts vary depending on the amount of data you index into the Elasticsearch cluster. Heavily used Elasticsearch clusters may require more resources. According to
-[Elasticsearch official guidelines](https://www.elastic.co/guide/en/elasticsearch/guide/current/hardware.html#_memory),
-each node should have:
-
-- [Memory](https://www.elastic.co/guide/en/elasticsearch/guide/current/hardware.html#_memory): 8 GiB (minimum).
-- [CPU](https://www.elastic.co/guide/en/elasticsearch/guide/current/hardware.html#_cpus): Modern processor with multiple cores. GitLab has minimal CPU requirements for Elasticsearch. Multiple cores provide extra concurrency, which is more beneficial than faster CPUs.
-- [Storage](https://www.elastic.co/guide/en/elasticsearch/guide/current/hardware.html#_disks): Use SSD storage. The total storage size of all Elasticsearch nodes is about 50% of the total size of your Git repositories. It includes one primary and one replica. The [`estimate_cluster_size`](#gitlab-advanced-search-rake-tasks) Rake task ([introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/221177) in GitLab 13.10) uses total repository size to estimate the Advanced Search storage requirements.

+### Access requirements for self-managed AWS OpenSearch Service using fine-grained access control
+
+To use the self-managed AWS OpenSearch Service with GitLab using fine-grained access control, try one of the
+[recommended configurations](https://docs.aws.amazon.com/opensearch-service/latest/developerguide/fgac.html#fgac-recommendations).
+
+Configure your instance's domain access policies to allow `es:ESHttp*` actions. You can customize
+the following example configuration to limit principals or resources.
+See [Identity and Access Management in Amazon OpenSearch Service](https://docs.aws.amazon.com/opensearch-service/latest/developerguide/ac.html) for details.
+
+```json

+ "AWS": [
+ "*"
+ ]
+ },
+ "Action": [
+ "es:ESHttp*"
+ ],
+ "Resource": "domain-arn/*"
+ }
+ ]
+}
+```
+
+#### Connecting with a master user in the internal database
+
+When using fine-grained access control with a user in the internal database, you should use HTTP basic
+authentication to connect to OpenSearch. You can provide the master username and password as part of the
+OpenSearch URL or in the **Username** and **Password** text boxes in the Advanced Search settings. See
+[Tutorial: Internal user database and HTTP basic authentication](https://docs.aws.amazon.com/opensearch-service/latest/developerguide/fgac-walkthrough-basic.html) for details.
+
+#### Connecting with an IAM user
+
+When using fine-grained access control with IAM credentials, you can provide the credentials in the **AWS OpenSearch IAM credentials** section in the Advanced Search settings.
+
+#### Permissions for fine-grained access control
+
+The following permissions are required for Advanced Search. See [Creating roles](https://docs.aws.amazon.com/opensearch-service/latest/developerguide/fgac.html#fgac-roles) for details.
+
+```json
+{
+ "cluster_permissions": [
+ "cluster_composite_ops",
+ "cluster_monitor"
+ ],
+ "index_permissions": [
+ {
+ "index_patterns": [

+# GitLab CLI - `glab`
+
+GLab is an open source GitLab CLI tool. It brings GitLab to your terminal:
+next to where you are already working with Git and your code, without
+switching between windows and browser tabs.
+
+- Work with issues.
+- Work with merge requests.
+- Watch running pipelines directly from your CLI.
+
+![command example](img/glabgettingstarted.gif)
+
+The GitLab CLI uses commands structured like `glab <command> <subcommand> [flags]`
+to perform many of the actions you normally do from the GitLab user interface:
+
+```shell
+# Sign in
+glab auth login --stdin < token.txt
+
+# View a list of issues
+glab issue list
+
+# Create merge request for issue 123
+glab mr for 123
+
+# Check out the branch for merge request 243
+glab mr checkout 243
+
+# Watch the pipeline in progress
+glab pipeline ci view
+
+# View, approve, and merge the merge request
+glab mr view
+glab mr approve
+glab mr merge
+```
+
+## Core commands
+
+- `glab alias`
+- `glab api`
+- `glab auth`

-|--------------------------------|-------------|
-| Identity provider (IdP) | The service which manages your user identities, such as Okta or OneLogin. |
-| Service provider (SP) | GitLab can be configured as a SAML 2.0 SP. |
-| Assertion | A piece of information about a user's identity, such as their name or role. Also known as claims or attributes. |
-| Single Sign-On (SSO) | Name of authentication scheme. |
-| Assertion consumer service URL | The callback on GitLab where users are redirected after successfully authenticating with the identity provider. |
-| Issuer | How GitLab identifies itself to the identity provider. Also known as a "Relying party trust identifier". |
-| Certificate fingerprint | Used to confirm that communications over SAML are secure by checking that the server is signing communications with the correct certificate. Also known as a certificate thumbprint. |

-### Notes on configuring your identity provider
+## Set up identity providers
-When configuring a SAML app on the IdP, you need at least:
+GitLab support of SAML means you can sign in to GitLab through a wide range
+of IdPs.
-- Assertion consumer service URL
-- Issuer
-- [`NameID`](../user/group/saml_sso/index.md#nameid)
-- [Email address claim](#assertions)
+GitLab provides the following content on setting up the Okta and Google Workspace
+IdPs for guidance only. If you have any questions on configuring either of these
+IdPs, contact your provider's support.
-Your identity provider may require additional configuration, such as the following:

-| Field | Value | Notes |
-|-------|-------|-------|
-| SAML profile | Web browser SSO profile | GitLab uses SAML to sign users in through their browser. No requests are made directly to the identity provider. |
-| SAML request binding | HTTP Redirect | GitLab (the service provider) redirects users to your identity provider with a base64 encoded `SAMLRequest` HTTP parameter. |
-| SAML response binding | HTTP POST | Specifies how the SAML token is sent by your identity provider. Includes the `SAMLResponse`, which a user's browser submits back to GitLab. |
-| Sign SAML response | Required | Prevents tampering. |
-| X.509 certificate in response | Required | Signs the response and checks against the provided fingerprint. |
-| Fingerprint algorithm | SHA-1 | GitLab uses a SHA-1 hash of the certificate to sign the SAML Response. |
-| Signature algorithm | SHA-1/SHA-256/SHA-384/SHA-512 | Determines how a response is signed. Also known as the digest method, this can be specified in the SAML response. |
-| Encrypt SAML assertion | Optional | Uses TLS between your identity provider, the user's browser, and GitLab. |
-| Sign SAML assertion | Optional | Validates the integrity of a SAML assertion. When active, signs the whole response. |
-| Check SAML request signature | Optional | Checks the signature on the SAML response. |
-| Default RelayState | Optional | Specifies the URL users should end up on after successfully signing in through SAML at your identity provider. |
-| NameID format | Persistent | See [NameID format details](../user/group/saml_sso/index.md#nameid-format). |
-| Additional URLs | Optional | May include the issuer (or identifier) or the assertion consumer service URL in other fields on some providers. |

-## Providers
-
-GitLab support of SAML means that you can sign in to GitLab with a wide range of identity providers.
-Your identity provider may have additional documentation. Some identity providers include
-documentation on how to use SAML to sign in to GitLab.
-
-Examples:
-
-- [ADFS (Active Directory Federation Services)](https://learn.microsoft.com/en-us/windows-server/identity/ad-fs/operations/create-a-relying-party-trust)
-- [Auth0](https://auth0.com/docs/authenticate/protocols/saml/saml-sso-integrations/configure-auth0-saml-identity-provider)
-
-GitLab provides the following setup notes for guidance only.
-If you have any questions on configuring the SAML app, please contact your provider's support.
-
-### Okta setup notes
-
-1. In the Okta administrator section choose **Applications**.
-1. When the app screen comes up you see another button to **Create App Integration** and
- choose SAML 2.0 on the next screen.
-1. Optionally, you can add a logo
- (you can choose it from <https://about.gitlab.com/press/>). You must
- crop and resize it.
-1. Next, fill in the SAML general configuration with
- the assertion consumer service URL as "Single sign-on URL" and
- the issuer as "Audience URI" along with the [NameID](../user/group/saml_sso/index.md#nameid) and [assertions](#assertions).
-1. The last part of the configuration is the feedback section where you can
- just say you're a customer and creating an app for internal use.
-1. When you have your app you can see a few tabs on the top of the app's
- profile. Select the SAML 2.0 configuration instructions button.
-1. On the screen that comes up take note of the
- **Identity Provider Single Sign-On URL** which you can use for the
- `idp_sso_target_url` on your GitLab configuration file.
-1. **Before you leave Okta, make sure you add your user and groups if any.**

-### Google workspace setup notes
-
-The following guidance is based on this Google Workspace article, on how to [Set up your own custom SAML application](https://support.google.com/a/answer/6087519?hl=en):
-
-Make sure you have access to a Google Workspace [Super Admin](https://support.google.com/a/answer/2405986#super_admin) account.
- Use the information below and follow the instructions in the linked Google Workspace article.
-
-| | Typical value | Description |
-|------------------|--------------------------------------------------|----------------------------------------------------------|
-| Name of SAML App | GitLab | Other names OK. |
-| ACS URL | `https://<GITLAB_DOMAIN>/users/auth/saml/callback` | ACS is short for Assertion Consumer Service. |
-| GITLAB_DOMAIN | `gitlab.example.com` | Set to the domain of your GitLab instance. |
-| Entity ID | `https://gitlab.example.com` | A value unique to your SAML app, set it to the `issuer` in your GitLab configuration. |
-| Name ID format | EMAIL | Required value. Also known as `name_identifier_format` |
-| Name ID | Primary email address | Make sure someone receives content sent to that address |
-| First name | `first_name` | Required value to communicate with GitLab. |
-| Last name | `last_name` | Required value to communicate with GitLab. |
+## Additional configuration for SAML apps on your IdP
-You also must setup the following SAML attribute mappings:
+When configuring a SAML app on the IdP, your identity provider may require additional configuration, such as the following:
-| Google Directory attributes | App attributes |
-|-----------------------------------|----------------|
-| Basic information > Email | `email` |
-| Basic Information > First name | `first_name` |
-| Basic Information > Last name | `last_name` |
-
-You may also use some of this information when you [configure GitLab](#general-setup).
+| Field | Value | Notes |
+|-------|-------|-------|
+| SAML profile | Web browser SSO profile | GitLab uses SAML to sign users in through their browser. No requests are made directly to the identity provider. |
+| SAML request binding | HTTP Redirect | GitLab (the service provider) redirects users to your identity provider with a base64 encoded `SAMLRequest` HTTP parameter. |
+| SAML response binding | HTTP POST | Specifies how the SAML token is sent by your identity provider. Includes the `SAMLResponse`, which a user's browser submits back to GitLab. |
+| Sign SAML response | Required | Prevents tampering. |
+| X.509 certificate in response | Required | Signs the response and checks against the provided fingerprint. |
+| Fingerprint algorithm | SHA-1 | GitLab uses a SHA-1 hash of the certificate to sign the SAML Response. |
+| Signature algorithm | SHA-1/SHA-256/SHA-384/SHA-512 | Determines how a response is signed. Also known as the digest method, this can be specified in the SAML response. |
+| Encrypt SAML assertion | Optional | Uses TLS between your identity provider, the user's browser, and GitLab. |
+| Sign SAML assertion | Optional | Validates the integrity of a SAML assertion. When active, signs the whole response. |
+| Check SAML request signature | Optional | Checks the signature on the SAML response. |
+| Default RelayState | Optional | Specifies the URL users should end up on after successfully signing in through SAML at your identity provider. |
+| NameID format | Persistent | See [NameID format details](../user/group/saml_sso/index.md#nameid-format). |
+| Additional URLs | Optional | May include the issuer (or identifier) or the assertion consumer service URL in other fields on some providers. |
-When configuring the Google Workspace SAML app, be sure to record the following information:
+For example configurations, see the [notes on specific providers](#set-up-identity-providers).
-| | Value | Description |
-|-------------|--------------|-----------------------------------------------------------------------------------|
-| SSO URL | Depends | Google Identity Provider details. Set to the GitLab `idp_sso_target_url` setting. |
-| Certificate | Downloadable | Run `openssl x509 -in <your_certificate.crt> -noout -fingerprint` to generate the SHA1 fingerprint that can be used in the `idp_cert_fingerprint` setting. |
+## Glossary of common terms
-While the Google Workspace Administrator provides IdP metadata, Entity ID, and SHA-256
-fingerprint, they are not required. GitLab does not need that information to
-connect to the Google Workspace SAML app.
+| Term | Description |
+|--------------------------------|-------------|
+| Identity provider (IdP) | The service which manages your user identities, such as Okta or OneLogin. |
+| Service provider (SP) | GitLab can be configured as a SAML 2.0 SP. |
+| Assertion | A piece of information about a user's identity, such as their name or role. Also known as claims or attributes. |
+| Single Sign-On (SSO) | Name of authentication scheme. |
+| Assertion consumer service URL | The callback on GitLab where users are redirected after successfully authenticating with the identity provider. |
+| Issuer | How GitLab identifies itself to the identity provider. Also known as a "Relying party trust identifier". |
+| Certificate fingerprint | Used to confirm that communications over SAML are secure by checking that the server is signing communications with the correct certificate. Also known as a certificate thumbprint. |
