multiple registry containers, one gluster directory shared

[eskuai]

Hello,

I am trying to run the following use case, get a hight performance registry containers clusters ... i dont care about loadbalances, ipvs, etc..

We got 3 docker containers registry in 3 master nodes on k8s, running as container not as pod.

I want to use gluster as mount directory and all 3 registry share the directory glusferfs mounted, ie,
data-root is a glusterfs directory, SAME for all containers registry.

When implement this config using docker.cfg, we got a lot of error about mount /var/lib,

It seems that each registry "collect and save" in gluster fs and registry directory a lot of "individual" registry info.

what we got:

Save space disk, one volume glusterfs
fault-tolerant by using glusterfs
Same image availabity from all registries

How can i runt it ?

could is it a PR?

Tx
