Quick Answer
CI/CD versioning: tag Docker images with Git commit SHA (not just "latest"). Store the deployed version in a manifest. When promoting across environments (dev -> staging -> prod), promote the same image by SHA. API versioning in CI/CD: maintain old API version branches, run both in parallel, use feature flags to control rollout of breaking changes.

Container images and APIs are versioned using semantic versioning. Allows rollback and compatibility management. Ensures controlled deployment lifecycle.
