Docker registry supports using openstack swift to read/write images, we'll need to setup access to our existing swift cluster and run some experiments. The swift cluster in esams is currently idle and can be used for such experiments without impacting production. Latency will suffer a bit both from eqiad <-> esams networking and the fact that esams has both data and metadata on spinning disks (eqiad/codfw have metadata on SSD and data on spinning disks).
- Setup LVS for swift in esams
- Add docker registry production credentials to swift esams
- Create container for docker registry user to read/write
