Create Pull Request

CI GitHub Marketplace

A GitHub action to create a pull request for changes to your repository in the actions workspace.

Changes to a repository in the Actions workspace persist between steps in a workflow. This action is designed to be used in conjunction with other steps that modify or add files to your repository. The changes will be automatically committed to a new branch and a pull request created.

Create Pull Request action will:

  1. Check for repository changes in the Actions workspace. This includes:
    • untracked (new) files
    • tracked (modified) files
    • commits made during the workflow that have not been pushed
  2. Commit all changes to a new branch, or update an existing pull request branch.
  3. Create a pull request to merge the new branch into the base—the branch checked out in the workflow.

Usage

      - uses: actions/checkout@v4

      # Make changes to pull request here

      - name: Create Pull Request
        uses: peter-evans/create-pull-request@v7

You can also pin to a specific release version in the format @v7.x.x

Workflow permissions

For this action to work you must explicitly allow GitHub Actions to create pull requests. This setting can be found in a repository's settings under Actions > General > Workflow permissions.

For repositories belonging to an organization, this setting can be managed by admins in organization settings under Actions > General > Workflow permissions.

Action inputs

All inputs are optional. If not set, sensible defaults will be used.

Name Description Default
token The token that the action will use to create and update the pull request. See token. GITHUB_TOKEN
branch-token The token that the action will use to create and update the branch. See branch-token. Defaults to the value of token
path Relative path under GITHUB_WORKSPACE to the repository. GITHUB_WORKSPACE
add-paths A comma or newline-separated list of file paths to commit. Paths should follow git's pathspec syntax. If no paths are specified, all new and modified files are added. See Add specific paths.
commit-message The message to use when committing changes. See commit-message. [create-pull-request] automated change
committer The committer name and email address in the format Display Name <email@address.com>. Defaults to the GitHub Actions bot user on github.com. github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>

token

The token input defaults to the repository's GITHUB_TOKEN.

[!IMPORTANT]

  • If you want pull requests created by this action to trigger an on: push or on: pull_request workflow then you cannot use the default GITHUB_TOKEN. See the documentation here for further details.
  • If using the repository's GITHUB_TOKEN and your repository was created after 2nd February 2023, the default permission is read-only. Elevate the permissions in your workflow.
    permissions:
    contents: write
    pull-requests: write

Other token options:

[!TIP]
If pull requests could contain changes to Actions workflows you may also need the workflows scope.

branch-token

The action first creates a branch, and then creates a pull request for the branch. For some rare use cases it can be useful, or even neccessary, to use different tokens for these operations. It is not advisable to use this input unless you know you need to.

commit-message

In addition to a message, the commit-message input can also be used to populate the commit description. Leave a single blank line between the message and description.

          commit-message: |
            the first line is the commit message

            the commit description starts
            after a blank line and can be
            multiple lines

delete-branch

The delete-branch feature doesn't delete branches immediately on merge. (It can't do that because it would require the merge to somehow trigger the action.) The intention of the feature is that when the action next runs it will delete the branch if there is no diff.

Enabling this feature leads to the following behaviour:

  1. If a pull request was merged and the branch is left undeleted, when the action next runs it will delete the branch if there is no further diff.
  2. If a pull request is open, but there is now no longer a diff and the PR is unnecessary, the action will delete the branch causing the PR to close.

If you want branches to be deleted immediately on merge then you should use GitHub's Automatically delete head branches feature in your repository settings.

Proxy support

For self-hosted runners behind a corporate proxy set the https_proxy environment variable.

      - name: Create Pull Request
        uses: peter-evans/create-pull-request@v7
        env:
          https_proxy: http://<proxy_address>:<port>

Action outputs

The following outputs can be used by subsequent workflow steps.

Step outputs can be accessed as in the following example. Note that in order to read the step outputs the action step must have an id.

      - name: Create Pull Request
        id: cpr
        uses: peter-evans/create-pull-request@v7
      - name: Check outputs
        if: ${{ steps.cpr.outputs.pull-request-number }}
        run: |
          echo "Pull Request Number - ${{ steps.cpr.outputs.pull-request-number }}"
          echo "Pull Request URL - ${{ steps.cpr.outputs.pull-request-url }}"

Action behaviour

The default behaviour of the action is to create a pull request that will be continually updated with new changes until it is merged or closed. Changes are committed and pushed to a fixed-name branch, the name of which can be configured with the branch input. Any subsequent changes will be committed to the same branch and reflected in the open pull request.

How the action behaves:

For further details about how the action works and usage guidelines, see Concepts, guidelines and advanced usage.

Alternative strategy - Always create a new pull request branch

For some use cases it may be desirable to always create a new unique branch each time there are changes to be committed. This strategy is not recommended because if not used carefully it could result in multiple pull requests being created unnecessarily. If in doubt, use the default strategy of creating an updating a fixed-name branch.

To use this strategy, set input branch-suffix with one of the following options.

Controlling committed files

The action defaults to adding all new and modified files. If there are files that should not be included in the pull request, you can use the following methods to control the committed content.

Remove files

The most straightforward way to handle unwanted files is simply to remove them in a step before the action runs.

      - run: |
          rm -rf temp-dir
          rm temp-file.txt

Ignore files

If there are files or directories you want to ignore you can simply add them to a .gitignore file at the root of your repository. The action will respect this file.

Add specific paths

You can control which files are committed with the add-paths input. Paths should follow git's pathspec syntax. File changes that do not match one of the paths will be stashed and restored after the action has completed.

      - name: Create Pull Request
        uses: peter-evans/create-pull-request@v7
        with:
          add-paths: |
            *.java
            docs/*.md

Create your own commits

As well as relying on the action to handle uncommitted changes, you can additionally make your own commits before the action runs. Note that the repository must be checked out on a branch with a remote, it won't work for events which checkout a commit.

    steps:
      - uses: actions/checkout@v4
      - name: Create commits
        run: |
          git config user.name 'Peter Evans'
          git config user.email 'peter-evans@users.noreply.github.com'
          date +%s > report.txt
          git commit -am "Modify tracked file during workflow"
          date +%s > new-report.txt
          git add -A
          git commit -m "Add untracked file during workflow"
      - name: Uncommitted change
        run: date +%s > report.txt
      - name: Create Pull Request
        uses: peter-evans/create-pull-request@v7

Auto-merge

Auto-merge can be enabled on a pull request allowing it to be automatically merged once requirements have been satisfied. See enable-pull-request-automerge action for usage details.

Reference Example

The following workflow sets many of the action's inputs for reference purposes. Check the defaults to avoid setting inputs unnecessarily.

See examples for more realistic use cases.

jobs:
  createPullRequest:
    runs-on: ubuntu-latest

      - name: Create Pull Request
        id: cpr
        uses: peter-evans/create-pull-request@v7
        with:
          token: ${{ secrets.PAT }}
          commit-message: Update report
