Protected branches: - Control which users can merge and push code changes. - Prevent accidental deletion of critical branches. - Enforce code review and approval processes. - Manage [Code Owner approval](protection_rules.md#code-owner-approval) requirements. - Regulate force push permissions to maintain commit history. - Control access through both the UI and the [Protected branches API](../../../../api/protected_branches.md). {{< alert type="note" >}} The [default branch](default.md) for your repository is protected by default. {{< /alert >}} For information about how protection rules behave when a branch matches multiple rules or has complex permission requirements, see [Protection rules and permissions](protection_rules.md). ## Protect a branch Configure protected branches for individual projects or for all projects in a group. ### In a project Prerequisites: - You must have at least the Maintainer role. - When granting a group **Allowed to merge** or **Allowed to push and merge** permissions on a protected branch, the project must be accessible and shared with the group. For more information, see [Shared projects](../../members/sharing_projects_groups.md). To protect a branch: 1. On the left sidebar, select **Search or go to** and find your project. 1. Select **Settings > Repository**. 1. Expand **Protected branches**. 1. Select **Add protected branch**. 1. From the **Branch** dropdown list, select the branch you want to protect. 1. From the **Allowed to merge** list, select a role that can merge into this branch. 1. From the **Allowed to push and merge** list, select a role that can push to this branch. {{< alert type="note" >}} In GitLab Premium and Ultimate, you can also add groups or individual users to **Allowed to merge** and **Allowed to push and merge**. {{< /alert >}} 1. Select **Protect**. The protected branch displays in the list of protected branches. ### In a group {{< details >}} - Tier: Premium, Ultimate - Offering: GitLab Self-Managed {{< /details >}} {{< history >}} - [Generally available](https://gitlab.com/gitlab-org/gitlab/-/issues/500250) in GitLab 17.6. Feature flag `group_protected_branches` removed. {{< /history >}} Group owners can create protected branches for a group. These settings are inherited by all projects in the group and can't be overridden by project settings. Prerequisites: - You must have the Owner role for the group. - The group must be a top-level group. Subgroups are not supported. To protect a branch for all the projects in a group: 1. On the left sidebar, select **Search or go to** and find your group. 1. Select **Settings > Repository**. 1. Expand **Protected branches**. 1. Select **Add protected branch**. 1. In the **Branch** text box, type the branch name or a wildcard. Branch names and wildcards [are case-sensitive](_index.md#name-your-branch). 1. From the **Allowed to merge** list, select a role that can merge into this branch. 1. From the **Allowed to push and merge** list, select a role that can push to this branch. 1. Select **Protect**. The protected branch is added to the list of protected branches. ## Default branch protection settings Administrators can [set a default branch protection level](default.md#for-all-projects-in-an-instance) in the **Admin** area. ## Use wildcard rules When using wildcards, multiple rules can apply to a single branch. If more than one rule applies to a branch, the most permissive rule controls how the branch behaves. For merge controls to work properly, set **Allowed to push and merge** to a broader set of users than **Allowed to merge**. Prerequisites: - You must have at least the Maintainer role. To protect multiple branches at the same time: 1. On the left sidebar, select **Search or go to** and find your project. 1. Select **Settings > Repository**. 1. Expand **Protected branches**. 1. Select **Add protected branch**. 1. From the **Branch** dropdown list, type the branch name and a wildcard. Branch names and wildcards [are case-sensitive](_index.md#name-your-branch). For example: | Wildcard protected branch | Matching branches | |---------------------------|--------------------------------------------------------| | `*-stable` | `production-stable`, `staging-stable` | | `production/*` | `production/app-server`, `production/load-balancer` | | `*gitlab*` | `gitlab`, `gitlab/staging`, `master/gitlab/production` | 1. From the **Allowed to merge** list, select a role that can merge into this branch. 1. From the **Allowed to push and merge** list, select a role that can push to this branch. In GitLab Premium or Ultimate, you can also add groups or individual users. 1. Select **Protect**. The protected branch displays in the list of protected branches. ## Configure protection options You can set various protection options to secure your branches. ### Require merge requests You can force everyone to submit a merge request, rather than allowing them to check in directly to a protected branch: 1. On the left sidebar, select **Search or go to** and find your project. 1. Select **Settings > Repository**. 1. Expand **Protected branches**. 1. Select **Add protected branch**. 1. From the **Branch** dropdown list, select the branch you want to protect. 1. From the **Allowed to merge** list, select **Developers + Maintainers**. 1. From the **Allowed to push and merge** list, select **No one**. 1. Select **Protect**. Alternatively, you can [create](branch_rules.md#create-a-branch-rule) or [edit](branch_rules.md#edit-a-branch-rule-target) a branch rule. Then: 1. Select **Edit** in the **Allowed to merge** section. 1. Select **Developers and Maintainers**. 1. Select **Save changes**. ### Allow direct push You can allow everyone with write access to push directly to the protected branch. 1. On the left sidebar, select **Search or go to** and find your project. 1. Select **Settings > Repository**. 1. Expand **Protected branches**. 1. Select **Add protected branch**. 1. From the **Branch** dropdown list, select the branch you want to protect. 1. From the **Allowed to push and merge** list, select **Developers + Maintainers**. 1. Select **Protect**. Alternatively, you can [create](branch_rules.md#create-a-branch-rule) or [edit](branch_rules.md#edit-a-branch-rule-target) a branch rule. Then: 1. Select **Edit** in the **Allowed to push and merge** section. 1. Select **Developers and Maintainers**. 1. Select **Save changes**. ### With group permissions To set the members of a group or subgroup as **Allowed to merge** or **Allowed to push and merge** to a protected branch: 1. On the left sidebar, select **Search or go to** and find your project. 1. Select **Settings > Repository**. 1. Expand **Protected branches**. 1. Add groups to the following fields: ```plaintext # Allow group members to merge into this branch Allowed to merge: @group-x # Allow group members to push and merge into this branch Allowed to push and merge: @group-x/subgroup-y ``` {{< alert type="note" >}} When you assign a group to a protected branch, only direct members of that group are included. Members from parent groups are not automatically granted permissions to the protected branch. {{< /alert >}} #### Group inheritance requirements ```mermaid %%{init: { "fontFamily": "GitLab Sans" }}%% graph TD accTitle: Diagram of group inheritance for protected branches accDescr: If a project is shared with a group, the group members inherit permissions for protected branches. A[Parent group X] -->|owns| B[Project A] A -->|contains| C[Subgroup Y] B -->|shared with| C C -->|members inherit permissions| B ``` In this example: - Parent group X (`group-x`) owns Project A. - Parent group X also contains a subgroup, Subgroup Y. (`group-x/subgroup-y`) - Project A is shared with Subgroup Y. The eligible groups for protected branch permissions are: - Project A: Both Group X and Subgroup Y, because Project A is shared with Subgroup Y. #### Share projects with groups You can share the project with a group or subgroup so that their members are eligible for protected branch permissions. ```mermaid %%{init: { "fontFamily": "GitLab Sans" }}%% graph LR accTitle: Diagram of project sharing for protected branch permissions accDescr: Sharing a project with a group affects whether their members can have protected branch permissions. A[Parent group X] -->|owns| B[Project A] A -->|also contains| C[Subgroup Y] C -.->D{Share Project A
with Subgroup Y?} -.->|yes| E[Members of Subgroup Y
can have protected
branch permissions] D{Share Project A
with Subgroup Y?} -.->|no| F[Members of Subgroup Y
cannot have protected
branch permissions] E -.->|Add Subgroup Y
to protected branch settings| I[Subgroup Y members
can merge/push] -.-> B F -.-> |Add Subgroup Y
to protected branch settings| J[Settings will not
take effect] -.-> B ``` To grant access to Subgroup Y members for Project A, you must share the project with the subgroup. Adding the subgroup directly to the protected branch settings is not effective and isn't applicable to subgroup members. {{< alert type="note" >}} For a group to have protected branch permissions, the project must be directly shared with the group. Inherited project membership from parent groups is not sufficient for protected branch permissions. {{< /alert >}} ### Enable deploy key access You can push to a protected branch with a [deploy key](../../deploy_keys/_index.md). Prerequisites: - The deploy key must be enabled for your project. A project deploy key is enabled by default when it is created. However, a public deploy key must be [granted](../../deploy_keys/_index.md#grant-project-access-to-a-public-deploy-key) access to the project. - The deploy key must have [write access](../../deploy_keys/_index.md#permissions) to your project repository. - The owner of the deploy key must have at least read access to the project. - The owner of the deploy key must also be a member of the project. To allow a deploy key to push to a protected branch: 1. On the left sidebar, select **Search or go to** and find your project. 1. Select **Settings > Repository**. 1. Expand **Protected branches**. 1. Select **Add protected branch**. 1. From the **Branch** dropdown list, select the branch you want to protect. 1. From the **Allowed to push and merge** list, select the deploy key. 1. Select **Protect**. Deploy keys are not available in the **Allowed to merge** dropdown list. ### Allow force push You can allow [force pushes](../../../../topics/git/git_rebase.md#force-push-to-a-remote-branch) to protected branches. To protect a new branch and enable force push: 1. On the left sidebar, select **Search or go to** and find your project. 1. Select **Settings > Repository**. 1. Expand **Protected branches**. 1. Select **Add protected branch**. 1. From the **Branch** dropdown list, select the branch you want to protect. 1. From the **Allowed to push and merge** and **Allowed to merge** lists, select the settings you want. 1. To allow all users with push access to force push, turn on the **Allowed to force push** toggle. 1. Select **Protect**. To enable force pushes on branches that are already protected: 1. On the left sidebar, select **Search or go to** and find your project. 1. Select **Settings > Repository**. 1. Expand **Protected branches**. 1. Select **Add protected branch**. 1. In the list of protected branches, next to the branch, turn on the **Allowed to force push** toggle. Alternatively, you can [create](branch_rules.md#create-a-branch-rule) or [edit](branch_rules.md#edit-a-branch-rule-target) a branch rule. Then: 1. In the list of protected branches, next to the branch, turn on the **Allowed to force push** toggle. Members who can push to this branch can now also force push. ### Require Code Owner approval {{< details >}} - Tier: Premium, Ultimate - Offering: GitLab.com, GitLab Self-Managed, GitLab Dedicated {{< /details >}} For a protected branch, you can require at least one approval by a [Code Owner](../../codeowners/_index.md). If a branch is protected by multiple rules, code owner approval is required if any of the applicable rules have **Required approval from code owners** enabled. To protect a new branch and enable Code Owner's approval: 1. On the left sidebar, select **Search or go to** and find your project. 1. Select **Settings > Repository**. 1. Expand **Protected branches**. 1. Select **Add protected branch**. 1. From the **Branch** dropdown list, select the branch you want to protect. 1. From the **Allowed to push and merge** and **Allowed to merge** lists, select the settings you want. 1. Turn on the **Require approval from code owners** toggle. 1. Select **Protect**. To enable Code Owner's approval on branches that are already protected: 1. On the left sidebar, select **Search or go to** and find your project. 1. Select **Settings > Repository**. 1. Expand **Protected branches**. 1. Select **Add protected branch**. 1. In the list of protected branches, next to the branch, turn on the **Code owner approval** toggle. Alternatively, you can [create](branch_rules.md#create-a-branch-rule) or [edit](branch_rules.md#edit-a-branch-rule-target) a branch rule. Then, in the list of protected branches, next to the branch, turn on the **Code owner approval** toggle. When enabled, all merge requests for these branches require approval by a Code Owner per matched rule before they can be merged. Additionally, direct pushes to the protected branch are denied if a rule is matched. Any user who is not specified in the `CODEOWNERS` file cannot push changes for the specified files or paths, unless they are specifically allowed to. You don't have to restrict developers from pushing directly to the protected branch. Instead, you can restrict pushing to certain files where a review by Code Owners is required. In [GitLab Premium 13.5 and later](https://gitlab.com/gitlab-org/gitlab/-/issues/35097), users and groups who are allowed to push to protected branches do not need a merge request to merge their feature branches. Thus, they can skip merge request approval rules, Code Owners included. ## CI/CD on protected branches The permission to merge or push to protected branches defines whether or not a user can run CI/CD pipelines and execute actions on jobs. Because [merge request pipelines](../../../../ci/pipelines/merge_request_pipelines.md) run on the source branch, a pipeline isn't created if the user opening a merge request does not have permission to merge or push to the source branch. See [Security on protected branches](../../../../ci/pipelines/_index.md#pipeline-security-on-protected-branches) for details about the pipelines security model. ## Create protected branches Prerequisites: - You must have at least the Developer role. - To create a protected branch, branch protection must be configured to [require everyone to submit merge requests for a protected branch](#require-merge-requests). To create a new branch with protections: 1. On the left sidebar, select **Search or go to** and find your project. 1. Select **Code > Branches**. 1. Select **New branch**. 1. Fill in the branch name and select an existing branch, tag, or commit to base the new branch on. If you [require everyone to submit merge requests for a protected branch](#require-merge-requests), only existing protected branches and commits that are already in protected branches are accepted. You can also use [the Branches API](../../../../api/branches.md) to create a branch with protections. If branch protection is configured to [allow everyone to push directly to a protected branch](#allow-direct-push), a branch with protections can also be created from the command line or a Git client application. ## Delete protected branches Users with at least the Maintainer role can manually delete protected branches by using the GitLab web interface: 1. On the left sidebar, select **Search or go to** and find your project. 1. Select **Code > Branches**. 1. Next to the branch you want to delete, select **Delete** ({{< icon name="remove" >}}). 1. On the confirmation dialog, enter the branch name and select **Yes, delete protected branch**. Branch names [are case-sensitive](_index.md#name-your-branch). Protected branches can only be deleted by using GitLab either from the UI or API. This prevents accidentally deleting a branch through local Git commands or third-party Git clients. ## Policy enforcement For security and compliance, you may implement a [merge request approval policy](../../../application_security/policies/merge_request_approval_policies.md#approval_settings) which affects settings otherwise defined in your instance, group, or projects. Policies may affect users ability to unprotect or delete branches, push or force push. ## Related topics - [Protection rules and permissions](protection_rules.md) - [Protected branches API](../../../../api/protected_branches.md) - [Branches](_index.md) - [Branches API](../../../../api/branches.md) - [Commits API](../../../../api/commits.md) - [Code Owners](../../codeowners/_index.md#code-owners-and-protected-branches) ## Troubleshooting ### Branch names are case-sensitive Branch names in `git` are case-sensitive. When configuring your protected branch, or your [target branch workflow](_index.md#configure-workflows-for-target-branches), `dev` is not the same `DEV` or `Dev`.
