We can see that dockercli save image to the path /tmp/clairctl/registry/blobs
While from the clairctl logs, we can see that it will check path docker.io/library/registry/blobs

If i push image without tag, it will push successfully.
If i push image with gcr.io and with tag, such as gcr.io/google-containers/etcd-amd64:3.0.17 , it also push successfully.
I found that push image with tag, the path will be http://172.18.0.4:34694/local/docker.io/library/redis/blobs/*******
While push image without tag, the path will be http://172.18.0.4:39827/local//redis/blobs/******
Could you please help to explain the logical and how to fix this issue?
