Delete Old Branches Action

Introduction

This simple GitHub Action will delete branches and optionally tags that haven't received a commit recently. The time since last commit is configurable.

The default behaviour is to exclude Github protected branches. Additional branches can be excluded using the extra_protected_branch_regex variable (see example below).

Disclaimer

Always run the GitHub action in dry-run mode to ensure that it will do the right thing before you actually let it do it. Also make sure that you have a full copy of the repository (git clone --mirror ...) in case something goes bad

Example usage

name: Cleanup old branches
on:
  push:
    branches:
      - master
      - develop
jobs:
  housekeeping:
    name: Cleanup old branches
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v2
      - name: Run delete-old-branches-action
        uses: beatlabs/delete-old-branches-action@v0.0.6
        with:
          repo_token: ${{ github.token }}
          date: '3 months ago'
          dry_run: true
          delete_tags: true
          minimum_tags: 5
          extra_protected_branch_regex: ^(foo|bar)$

Once you are happy switch, dry_run to false so the action actually does the job

Happy cleaning!
