Managing a branch protection rule

About branch protection rules

リポジトリ内のブランチ保護ルールは、特定のブランチ、すべてのブランチ、または fnmatch 構文で指定する名前のパターンに一致するあらゆるブランチに対して作成できます。 たとえば、release という単語を含む任意のブランチを保護するには、*release* のブランチ ルールを作成します。

You can create a rule for all current and future branches in your repository with the wildcard syntax *. Because GitHub uses the File::FNM_PATHNAME flag for the File.fnmatch syntax, the wildcard does not match directory separators (/). For example, qa/* will match all branches beginning with qa/ and containing a single slash. You can include multiple slashes with qa/**/*, and you can extend the qa string with qa**/**/* to make the rule more inclusive. For more information about syntax options for branch rules, see the fnmatch documentation.

If a repository has multiple protected branch rules that affect the same branches, the rules that include a specific branch name have the highest priority. If there is more than one protected branch rule that references the same specific branch name, then the branch rule created first will have higher priority.

Protected branch rules that mention a special character, such as *, ?, or ], are applied in the order they were created, so older rules with these characters have a higher priority.

To create an exception to an existing branch rule, you can create a new branch protection rule that is higher priority, such as a branch rule for a specific branch name.

For more information about each of the available branch protection settings, see "About protected branches."

Creating a branch protection rule

When you create a branch rule, the branch you specify doesn't have to exist yet in the repository.

1. GitHub.com で、リポジトリのメイン ページへ移動します。

2. リポジトリ名の下の [ 設定] をクリックします。

3. In the "Code and automation" section of the sidebar, click Branches.

4. [Branch protection rules](ブランチ保護ルール) の横にある [Add rule] (ルールの追加) をクリックします。

5. "Branch name pattern（ブランチ名のパターン）"の下で、保護したいブランチの名前もしくはパターンを入力してください。

6. Optionally, enable required pull requests.

   • Under "Protect matching branches", select Require a pull request before merging.

   • Optionally, to require approvals before a pull request can be merged, select Require approvals, click the Required number of approvals before merging drop-down menu, then select the number of approving reviews you would like to require on the branch.

   • Optionally, to dismiss a pull request approval review when a code-modifying commit is pushed to the branch, select Dismiss stale pull request approvals when new commits are pushed.

   • Optionally, to require review from a code owner when the pull request affects code that has a designated owner, select Require review from Code Owners. For more information, see "About code owners."

   • Optionally, to allow specific actors to push code to the branch without creating pull requests when they're required, select Allow specified actors to bypass required pull requests. Then, search for and select the actors who should be allowed to skip creating a pull request.

   • Optionally, if the repository is part of an organization, select Restrict who can dismiss pull request reviews. Then, search for and select the actors who are allowed to dismiss pull request reviews. For more information, see "Dismissing a pull request review."

7. Optionally, enable required status checks. For more information, see "About status checks."

   • Select Require status checks to pass before merging.
   • Optionally, to ensure that pull requests are tested with the latest code on the protected branch, select Require branches to be up to date before merging.
   • Search for status checks, selecting the checks you want to require.

8. Optionally, select Require conversation resolution before merging.

9. Optionally, select Require signed commits.

10. Optionally, select Require linear history.

11. Optionally, to merge pull requests using a merge queue, select Require merge queue. マージ キューの詳細については、「マージ キューの管理」を参照してください。

    Tip: The pull request merge queue feature is currently in limited public beta and subject to change. Organizations owners can request early access to the beta by joining the waitlist.

12. Optionally, to choose which environments the changes must be successfully deployed to before merging, select Require deployments to succeed before merging, then select the environments.

13. Optionally, select Do not allow bypassing the above settings.

14. Optionally, if your repository is owned by an organization using GitHub Team or GitHub Enterprise Cloud, enable branch restrictions.

    • Select Restrict who can push to matching branches.
    • Optionally, to also restrict the creation of matching branches, select Restrict pushes that create matching branches.
    • Search for and select the people, teams, or apps who will have permission to push to the protected branch or create a matching branch.

15. Optionally, under "Rules applied to everyone including administrators", select Allow force pushes.

    Then, choose who can force push to the branch.

    • Select Everyone to allow everyone with at least write permissions to the repository to force push to the branch, including those with admin permissions.

    • Select Specify who can force push to allow only specific actors to force push to the branch. Then, search for and select those actors.

      For more information about force pushes, see "Allow force pushes."

16. Optionally, select Allow deletions.

17. Click Create.
