Deletion and Cleanup of Docker Tags and Repositories

Artifactory natively supports removing tags and repositories and complies with the Docker Hub spec.

Deletion of Docker tags and repositories automatically cleans up any orphan layers that are left (layers not used by any other tag/repository).

Currently, the Docker client does not support DELETE commands, but deletion can be triggered manually. To delete an entire Docker repository using cURL, execute the following command:

curl -u<user:password> -X DELETE "<Artifactory URL>/artifactory/<Docker v2 repository name>/<image namespace>"

Or for a specific tag version:

curl -u<user:password> -X DELETE "<Artifactory URL>/artifactory/<Docker v2 repository name>/<image namespace>/<tag>"

For example, to remove the latest tag of an Ubuntu repository:

//Removing the latest tag from the "jfrog/ubuntu" repository
curl -uadmin:password -X DELETE "https://artprod.company.com/artifactory/dockerv2-local/jfrog/ubuntu/latest"

Limiting Unique Tags

To avoid clutter and bloat in your Docker registries caused by many snapshots being uploaded for an image, set the Max Unique Tags field in the Local Docker Repository configuration to limit the number of unique tags.
