[Ci-users] local caching for docker images

hi,

the docker-distribution package can act as a smart proxy for docker registries; and having a local cache inside the ci infra would help speed up a lot of the jobs I am working with at the moment there.

Do we have the space to host a cache of this nature ? I'd think a 15 to 20 GB of space is all we need.

Could we then have dns inside the ci infra use this cache for the dockerhub urls ?

Any objections to getting this in ?

regards
