When you delete images from Harbor, space is not automatically freed up. You must run garbage collection to free up space by removing blobs that are no longer referenced by a manifest from the file system.
|
|
|
|
## Run Garbage Collection
|
|
|
|
1. Log in to the Harbor interface with an account that has Harbor system administrator privileges.
|
|
1. Expand **Administration**, and select **Garbage Collection**.
|
|
1. Select the **'Garbage Collection'** tab.
|
|
|
|
|
|
|
|
1. To delete untagged artifacts, select the check box **Delete Untagged Artifacts**.
|
|
1. To run garbage collection immediately, click **GC Now**.
|
|
|
|
When you run garbage collection, Harbor goes into read-only mode. All modifications to the registry are prohibited.
|
|
|
|
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.
|
|
|
|
## Schedule Garbage Collection
|
|
|
|
1. Expand **Administration**, and select **Garbage Collection**.
|
|
1. Select the **'Garbage Collection'** tab.
|
|
1. Use the drop down-menu to select how often to run garbage collection.
|
|
|
|
|
|
|
|
* **None**: No garbage collection is scheduled.
|
|
* **Hourly**: Run garbage collection at the beginning of every hour.
|
|
* **Daily**: Run garbage collection at midnight every day.
|
|
