GitHub Actions for common Docker workflows (Forked from https://github.com/urcomputeringpal/actions-docker)
- If you haven't already, create a Google Cloud Project named after your GitHub username and follow the Container Registry Quickstart.
- Create a Service Account named after your GitHub repository.
- Add the Cloud Build Service Account role to this Service Account.
- Generate a key for this Service Account. Download a JSON key when prompted.
- Create a Secret on your repository named
GCLOUD_SERVICE_ACCOUNT_KEY(Settings > Secrets) with the contents of:
# Linux
cat path-to/key.json | base64 -w 0
# MacOS
cat path-to/key.json | base64 -b 0- 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,
buildmay succeed butpushwill return an error!
