What is this?
Image management covers registries, tags, digests, scanning, and promotion between environments.
Why should you care?
CloudVerse promotes digests from staging to prod — not mutable latest.
See it live — copy this example
Use AWS/Azure/GCP free tier or local Docker/Kind. Sketches and YAML are meant to be typed and adapted.
# promote by digest
# docker pull cloudverse/api:1.2.3
# docker push …@sha256:abc…
# prod deploy references digest, not :latestWhat happened?
- Private registry + vulnerability scan in CI.
- Retag carefully; prefer immutable digests for prod.
Practice next
- Push to a registry.
- Scan once.
- Deploy by digest in lab.
- Pin base image digest.
- Add retention policy.
Remember
Registry + scan. Immutable digests. Promote artifacts.
CloudVerse image promote
Staging digest → prod.
Outcome: Same bits that passed tests ship.
