Create Pull Request

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:

Check for repository changes in the Actions workspace. This includes untracked (new) files as well as modified files.
Commit all changes to a new branch, or update an existing pull request branch. The commit will be made using the name and email of the HEAD commit author.
Create a pull request to merge the new branch into the currently active branch executing the workflow.

Usage

Linux

      - name: Create Pull Request
        uses: peter-evans/create-pull-request@v1.4.0
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Multi platform - Linux, MacOS, Windows (beta)

      - name: Create Pull Request
        uses: peter-evans/create-pull-request@v1.4.0-multi
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Environment variables

These variables are all optional. If not set, a default value will be used.

COMMIT_MESSAGE - The message to use when committing changes.
PULL_REQUEST_TITLE - The title of the pull request.
PULL_REQUEST_BODY - The body of the pull request.
PULL_REQUEST_LABELS - A comma separated list of labels.
PULL_REQUEST_ASSIGNEES - A comma separated list of assignees (GitHub usernames).
PULL_REQUEST_REVIEWERS - A comma separated list of reviewers (GitHub usernames) to request a review from.
PULL_REQUEST_TEAM_REVIEWERS - A comma separated list of GitHub teams to request a review from.
PULL_REQUEST_MILESTONE - The number of the milestone to associate this pull request with.
PULL_REQUEST_BRANCH - The branch name. See Branch naming below for details.
BRANCH_SUFFIX - The branch suffix type. Valid values are short-commit-hash (default), timestamp, random and none. See Branch naming below for details.

Output environment variables

PULL_REQUEST_NUMBER - The number of the pull request created.

The following parameters are available for debugging and troubleshooting.

DEBUG_EVENT - If present, outputs the event data that triggered the workflow.
SKIP_IGNORE - If present, the ignore_event function will be skipped.

Branch naming

For branch naming there are two strategies. Always create a new branch each time there are changes to be committed, OR, create a fixed-name pull request branch that will be updated with any new commits until it is merged or closed.

Strategy A - Always create a new pull request branch (default)

For this strategy there are three options to suffix the branch name. The branch name is defined by the variable PULL_REQUEST_BRANCH and defaults to create-pull-request/patch. The following options are values for BRANCH_SUFFIX.

short-commit-hash (default) - Commits will be made to a branch suffixed with the short SHA1 commit hash. e.g. create-pull-request/patch-fcdfb59, create-pull-request/patch-394710b
timestamp - Commits will be made to a branch suffixed by a timestamp. e.g. create-pull-request/patch-1569322532, create-pull-request/patch-1569322552
random - Commits will be made to a branch suffixed with a random alpha-numeric string. This option should be used if multiple pull requests will be created during the execution of a workflow. e.g. create-pull-request/patch-6qj97jr, create-pull-request/patch-5jrjhvd

Strategy B - Create and update a pull request branch

To use this strategy, set BRANCH_SUFFIX to the value none. The variable PULL_REQUEST_BRANCH defaults to create-pull-request/patch. Commits will be made to this branch and a pull request created. Any subsequent changes will be committed to the same branch and reflected in the existing pull request.

Ignoring 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.

Example

Here is an example that sets all the main environment variables.

on:
  repository_dispatch:
    types: [create-pull-request]
name: create-pull-request workflow
jobs:
  createPullRequest:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1
      - name: Create report file
        run: date +%s > report.txt
      - name: Create Pull Request
        uses: peter-evans/create-pull-request@v1.4.0
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          COMMIT_MESSAGE: Add report file
          PULL_REQUEST_BODY: >
            This PR is auto-generated by 
            [create-pull-request](https://github.com/peter-evans/create-pull-request).            
          PULL_REQUEST_TITLE: '[Example] Add report file'
          PULL_REQUEST_LABELS: report, automated pr
          PULL_REQUEST_ASSIGNEES: peter-evans
          PULL_REQUEST_REVIEWERS: peter-evans
          PULL_REQUEST_MILESTONE: 1
          PULL_REQUEST_BRANCH: example-patches
          BRANCH_SUFFIX: short-commit-hash
      - name: Check output environment variable
        run: echo "Pull Request Number - $PULL_REQUEST_NUMBER"

This configuration will create pull requests that look like this:
