Garbage Collection
Online Garbage Collection enables user to trigger docker registry garbage collection by clicking button on UI.
NOTES: The space is not freed when the images are deleted from Harbor, Garbage Collection is the task to free up the space by removing blobs from the filesystem when they are no longer referenced by a manifest.
For more information about Garbage Collection, please see Garbage Collection.
Setting up Garbage Collection
If you are a system admin, you can trigger garbage collection by clicking "GC Now" in the 'Garbage Collection' tab of 'Configuration' section under 'Administration'.
NOTES: Harbor is put into read-only mode when to execute Garbage Collection, and any modification on docker registry is prohibited.
To avoid frequently triggering the garbage collection process, the availability of the button is restricted. It can be only triggered once in one minute.
