Container Registry
A container registry is a service that stores and shares container images. Repositories group related content inside the registry.

Registry `registry.example.com` contains repository `team/checkout`. A tag names a version; a digest identifies its exact manifest.
Main parts
- 01Registry host
- 02Repository path
- 03Tag
- 04Manifest digest
- 05Push and pull access
- 06Retention and audit rules
Use it when
Use a registry when build systems and runtime hosts need controlled image push and pull. Set access and retention rules. Configure audit logs when available.
Do not use it when
Do not call one repository the whole registry. Do not deploy an unknown tag without checking its digest and source.

Before publishing, check the exact repository, branch, target, and diff. Keep unpublished work. Pass review and CI checks. Record conflict and data-loss risks, release order, traceability, recovery, and rollback.
Outcome: Use Container Registry to release or recover the change safely, with a clear record. User context: Registry `registry.example.com` contains repository `team/checkout`. A tag names a version; a digest identifies its exact manifest. Delivery concept or operation: Container Registry. Why it fits: Use a registry when build systems and runtime hosts need controlled image push and pull. Set access and retention rules. Configure audit logs when available. Do not use it when: Do not call one repository the whole registry. Do not deploy an unknown tag without checking its digest and source. Delivery requirements: Name the code repository and target. List preconditions, changes, review and CI checks, conflict and data-loss risks, release order, and the rollback or recovery command. Repository safeguards: Keep unpublished work and a clear history. Do not run destructive steps without an explicit backup. Check the exact code diff and remote target before publishing. Acceptance criteria: Review the intended diff and pass all required checks. Keep the target version traceable. Practice failure recovery and keep published history clear. Evidence and limits (evidence boundary): A formal document may still be a draft, release candidate, or final version. Check its status and browser or platform support. Unknowns to confirm: Repository, branch, team activity, release environment, approval owner, protected checks, and rollback target.

Release checks: Before publishing, check the exact repository, branch, target, and diff. Keep unpublished work. Pass review and CI checks. Record conflict and data-loss risks, release order, traceability, recovery, and rollback. Before changing code, report the evidence you found, gaps, severity, and the smallest safe fix.
