Heroku Git Push

A simple GitHub Action that will push the main branch to the Heroku remote. Using GitHub secrets you can securely use your Heroku credentials to push changes from your main branch to multiple Heroku apps.

Important Notes

• Only works for branches named main or master by default
• The use of fetch-depth: 0 ensures Heroku will accept the push. See this changelog for details.

Usage

Create a workflow in .github/workflows called main.yml.

name: Heroku push

on:
  push:
    branches:
      - main

jobs:
  heroku_git_push:
    runs-on: ubuntu-latest
    name: Push code to Heroku
    steps:
      - name: Checkout
        uses: actions/checkout@v3
        with:
          fetch-depth: 0
      - name: Push code
        uses: yunojuno/heroku-git-push@v1
        with:
          email: ${{ secrets.HEROKU_PUSH_EMAIL }}
          api_key: ${{ secrets.HEROKU_PUSH_API_KEY }}
