  • That's it! The GitHub Actions in this repository read this Secret and provide the correct values to the Docker daemon by default if present. If a Secret isn't present, build may succeed but push will return an error!

Build and push images for each commit

Add the following to .github/workflows/docker.yaml:

name: Docker

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v1

        with:
          gcloud_key: ${{ secrets.GCLOUD_SERVICE_ACCOUNT_KEY }}
