Hi guys,

I am trying to delete an image as documentation states for V2 registries: $ curl -Ik -u <user:password> -H "Accept: application/vnd.docker.distribution.manifest.v2+json" https://<registry>/v2/<image>/manifests/<tag> | awk '$1 == "Docker-Content-Digest:" { print $2 }' | tr -d $'\r' $ curl -k -u <user:password> -X DELETE https://<registry>/v2/<image>/manifests/<digest>

However, I am getting {"errors":[{"code":"UNSUPPORTED","message":"The operation is unsupported."}]}. Please note that the env variable storage.delete.enabled: true is correctly set.

This endpoint deletes only leftovers and is used primarily by the image pruner.

If you want to delete an image, you need to use oc delete imagestreamtag IMAGESTREAM:TAG -n NAMESPACE.
