Branch Protection Bot

A bot tool to temporarily disable and re-enable Do not allow bypassing the above settings option in branch protection

Github doesn't have a way to give a Bot access to override the branch protection, specifically if you Do not allow bypassing the above settings. The only possible solution is to disable the Do not allow bypassing the above settings option. This increases risk of accidental pushes to master from administrators (I've done it a few times). This tool doesn't completely solve the problem of accidents happening but reduces the chances by closing the window.

The intended use of this tool is to is in a CI/CD pipeline where you require temporary access to allow a administrator Bot push to a branch.

Tutorial

How it works

1. Your automated pipeline is kicked off
2. Before you push to github you run this tool to disable Do not allow bypassing the above settings
3. Push to the repository
4. After you push to github you run this tool to enable Do not allow bypassing the above settings

Example usage

Docker

docker run -e ACCESS_TOKEN=abc123 -e BRANCH=master -e REPO=branch-protection-bot -e OWNER=benjefferies benjjefferies/branch-protection-bot

Github Actions

- name: Temporarily disable "Do not allow bypassing the above settings" branch protection
  uses: benjefferies/branch-protection-bot@master
  if: always()
  with:
    access_token: ${{ secrets.ACCESS_TOKEN }}
    branch: ${{ github.event.repository.default_branch }}
    
- name: Deploy
  run: |
    mvn release:prepare -B
    mvn release:perform -B
   
- name: Enable "Do not allow bypassing the above settings" branch protection
  uses: benjefferies/branch-protection-bot@master
  if: always()  # Force to always run this step to ensure "Do not allow bypassing the above settings" is always turned back on
  with:
    access_token: ${{ secrets.ACCESS_TOKEN }}
    owner: benjefferies
    repo: branch-protection-bot
    branch: ${{ github.event.repository.default_branch }}

Inputs

access_token

Required Github access token. https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line. See issue for required permissions

owner

For example benjefferies for https://github.com/benjefferies/branch-protection-bot. If not set with repo GITHUB_REPOSITORY variable will be used

repo

branch

Branch name. Default "master"

retries

Number of times to retry before exiting. Default 5.

enforce_admins

If you want to pin the state of Do not allow bypassing the above settings for a step in the workflow.

Outputs

initial_status

Output the current branch protection status of Do not allow bypassing the above settings prior to any change. You can retrieve it from any next step in your job using: ${{ steps.disable_include_admins.outputs.initial_status }}. This would help you to restore the initial setting this way:

steps:
    - name: "Temporarily disable 'Do not allow bypassing the above settings' default branch protection"
    id: disable_include_admins
    uses: benjefferies/branch-protection-bot@master
    if: always()
    with:
        access_token: ${{ secrets.ACCESS_TOKEN }}
        branch: ${{ github.event.repository.default_branch }}
        enforce_admins: false
    
    - ...

    - name: "Restore 'Do not allow bypassing the above settings' default branch protection"
    uses: benjefferies/branch-protection-bot@master
    if: always() # Force to always run this step to ensure "Do not allow bypassing the above settings" is always turned back on
    with:
        access_token: ${{ secrets.ACCESS_TOKEN }}
        branch: ${{ github.event.repository.default_branch }}
        enforce_admins: ${{ steps.disable_include_admins.outputs.initial_status }}

Github repository settings

The Bot account must be an administrator.
