This Github Action will automatically create backport pull request when a pull request is merged, based on the labels it contains.

Example

By merging a pull request with the labels backport-to-staging and backport-to-production Backport Github Action (BGA) will automatically create backport pull requests to the branches "staging" and "production".

How to use

Add the backport workflow to .github/workflows/backport.yml:

name: Backport
on:
  pull_request_target:
    types:
      - closed
      - labeled

jobs:
  backport:
    name: Backport Action
    runs-on: ubuntu-latest
    steps:
      - name: Backport
        uses: sqren/backport-github-action@v1
        with:
          # Required
          # Token to authenticate requests
          access_token: ${{ secrets.GITHUB_TOKEN }}

          # Required
          # Backport PR by adding a label
          # Example: PRs labeled with "backport-to-staging" will be backported to "staging"
          backport_by_label: '^backport-to-(.*)$'

          # Optional
          # Title for the backport PR
          # Example: [branch-a] My commit msg
          # pr_title: '[{targetBranch}] {commitMessages}'

          # Optional
          # Comma separated list of labels that will be added to the backport PR.
          # target_pr_labels: 'backport'

Backport CLI (optional)

Backport CLI is a tool that makes it much easier to create ad-hoc backport pull requests. This integrates seemlessly with the Backport Github Action. All you need to do is to add a backport configuration file to the repository root:

// .backportrc.json
{
  "upstream": "<repo name>/<repo owner>",
  "targetBranchChoices": ["master", "staging", "production", "<any other branch>"] 
}
