phpdockerio/github-actions-delete-abandoned-branches repository overview

⁠Delete abandoned branches

Github action to delete abandoned branches.

See: https://github.com/phpdocker-io/github-actions-delete-abandoned-branches⁠

⁠Warning

This action WILL delete branches from your repository, so you need to make your due diligence when choosing to use it and with which settings. I am not responsible for any mishaps that might occur.

⁠Abandoned branches

A branch must meet all the following criteria to be deemed abandoned and safe to delete:

• Must NOT be the default branch (eg master or main, depending on your repository settings)
• Must NOT be a protected branch
• Must NOT have any open pull requests
• Must NOT be the base of an open pull request of another branch. The base of a pull request is the branch you told GitHub you want to merge your pull request into.
• Must NOT be in an optional list of branches to ignore
• Must be older than a given amount of days

⁠Inputs

* mandatory

⁠Note: dry run

By default, the action will only perform a dry run. It will go in, gather all branches that qualify for deletion and give you the list on the actions' output, but without actually deleting anything. Make sure you configure your stuff correctly before setting dry_run to no

⁠Example

The following workflow will run on a schedule (daily at 00:00) and will delete all abandoned branches older than 100 days:

name: Delete abandoned branches

on:
  # Run daily at midnight
  schedule:
    - cron: "0 0 * * *"

  # Allow workflow to be manually run from the GitHub UI
  workflow_dispatch:

jobs:
  cleanup_old_branches:
    runs-on: ubuntu-latest
    name: Satisfy my repo CDO
    steps:
      - name: Delete those pesky dead branches
        uses: phpdocker-io/github-actions-delete-abandoned-branches@v1
        id: delete_stuff
        with:
          github_token: ${{ github.token }}
          last_commit_age_days: 100
          ignore_branches: next-version,dont-deleteme

          # Disable dry run and actually get stuff deleted
          dry_run: no

      - name: Get output
        run: "echo 'Deleted branches: ${{ steps.delete_stuff.outputs.deleted_branches }}'"
