Garbage Collection

When images are deleted from Harbor, space is not automatically freed-up. A garbage collection must be performed to free-up space by removing blobs (binary large objects) that are no longer referenced by a manifest from the file system.

To avoid triggering the garbage collection process too frequently, the availability of the "GC Now" button is restricted. Garbage collection can be only run once per minute.

Use the drop-down menu (visible once the "Edit" button is clicked) to select how often to run garbage collection.

Edit button

The "History" tab shows the 10 most recent Garbage Collection runs.
