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.
