Garbage collection

Mirantis Secure Registry (MSR) supports garbage collection, the automatic cleanup of unused image layers. You can configure garbage collection to occur at regularly scheduled times, as well as set a specific duration for the process.

Garbage collection first identifies and marks unused image layers, then subsequently deletes the layers that have been marked.
