GUIDES

Less guessing.
Better deployments.

Practical notes on the things between writing your code and running it with confidence.

Tags are labels. Digests identify what you deploy.

Understand container image tags, immutable digests and why artifact identity matters for predictable deployments and rollbacks.

Choose the right deployment action. Learn how current-image redeployment, saved-image deployment and artifact rollback affect your application.

Prepare your image, application port, environment variables and runtime user before deploying a container or Dockerfile-based GitHub application.

Bring your code. Make something people can use.
