Write-guard

Enforce file level write access for monorepos

Usage

Write-guard is designed to enforce file level write access for monorepos that have protected default branches (usually main or master) with

• Restrict push enabled
• Require status checks to pass before merging enabled.

:warning: If these are not enforced, file level write access cannot be enforced by write-guard.

Setup

you will need to define a write-guard.yaml in the root of your repository, eg.:

roles:
  - edit-all:
    - team/admins
    - permission/admin
    - user/geritol
access:
  **:
    - role/edit-all
  security/**:
    - team/security

You need to run write-guard on your pull requests eg.:

# .github/workflows/write-guard.yaml

name: Pull Request

on:
  pull_request:
    branches: [master]

jobs:
  write-guard:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2
        with:
          ref: master # Important!
          # write-guard needs to run on your master branch to prevent
          # the possibility of pr openers self grant edit permissions
          #
          # the action will retrieve files changed in the current pr
          # and validate write access based on the master branches
          # write-guard.yaml
      - name: write-guard
        uses: geritol/write-guard@v0.4.0
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
