Docker Registry deprecation

Estimated reading time: 1 minute

This document details functionality or components which are deprecated within the registry.


The signature store has been removed from the registry. Since v2.4.0 it has been possible to configure the registry to generate manifest signatures rather than load them from storage. In this version of the registry this becomes the default behavior. Signatures which are attached to manifests on put are not stored in the registry. This does not alter the functional behavior of the registry.

Old signatures blobs can be removed from the registry storage by running the garbage-collect subcommand.
