What container registries does the tag explorer support?

The explorer queries Docker Hub's public registry API. It shows all available tags, their sizes, architectures, and last-pushed dates for any public image.

Can I see image layer details?

Yes. The explorer shows the manifest digest, compressed size, OS/architecture combinations, and creation date for each tag.

Does it show multi-arch image support?

Yes. For images with multi-architecture manifests, the explorer lists all supported platforms (linux/amd64, linux/arm64, etc.) for each tag.

How do I find the latest stable tag?

Tags are sorted by push date by default. Look for tags following semantic versioning (like 3.19.0) rather than rolling tags (like latest or alpine) for reproducible builds.

📖 Common Tag Patterns

Size variants

latest — full image, may be large
alpine — minimal (~5MB), musl libc
slim — reduced Debian, no extras
bullseye/bookworm — Debian release name
scratch — zero-byte base layer

Best practices

Pin to an exact digest in production
Prefer node:18-alpine over node:latest
Use multi-arch images when possible
Check last pushed — stale tags = security risk
Avoid latest in CI/CD pipelines
