Getting applications running.
WHAT DEPLOYMENT APPROACHES EXIST
Building and deploying from a pipeline Deploying a container image Source-based deployment, where the platform builds for you
WHAT TO PREFER
A pipeline producing an artefact, deployed automatically.
WHY
Reproducible, reviewable, and not dependent on anyone's machine.
WHAT CLOUD BUILD PROVIDES
Building, testing and deploying, triggered by repository changes.
WHAT TO STORE IMAGES IN
The artefact registry, with versioned tags.
WHAT TO NEVER USE
A tag that moves, such as latest, for production deployments.
WHY
You cannot establish what is actually running, or roll back reliably.
WHAT TO CONFIGURE
Environment values outside the image Secrets from the secret manager, not environment variables in configuration
WHAT TO USE FOR SAFE RELEASE
Gradual traffic migration between revisions.
WHAT THAT PROVIDES
Sending a small proportion of traffic to a new version, and reverting instantly.
WHAT TO VERIFY AFTER DEPLOYING
The service responds Logs are clean Error rate is unchanged
WHAT TO KEEP
The previous revision, for reversal.
