The disconnected Clair setup docs should be updated to describe the use of "repo2cpe_mapping_url" and "name2repos_mapping_url". The current docs detail how to use "repo2cpe_mapping_file" and "name2repos_mapping_file'. When using the file approach, these files have to be mounted locally on the clair container which adds additional complexity of either using a PVC with a custom clair unmanaged deployment as per this KCS https://access.redhat.com/solutions/7051718

Using URLs is a cleaner approach and does not require any unmanaged clair deployment or PVCs to mount the mapping files. Ideally this should be detailed in our official docs
