Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

Common questions

How can I remove old tags or images from a private Docker registry?

You can query the registry to find tags or images and then delete the unwanted tags or images. The process can become more complicated when read-only mode and caches are involved.

What should I configure to manage a Docker registry that keeps growing?

The relevant controls are retention and purging policies. You should review the registry interfaces and policies that determine which images are retained or removed.

Can I expose Docker Registry under a non-root URL in a reverse proxy?

Workarounds are discussed for serving the registry from a URL that is not the root path.

Which common configuration areas should I check when Docker Registry fails?

Check configuration mistakes, storage issues, and authentication problems. These are the common Docker Registry error categories covered in the practical operations guide.
