Does anyone recommend some pull-through registry to use? Docker Docs has some recommendations [0], but I wonder how feature complete it is.

I'd like to find something that:

- Can pull and serve private images

- Has UI to show a list of downloaded images, and some statistics on how much storage and bandwidth they use

- Can run periodic GC to delete unused images

- (maybe) Can be set up to pre-download new tags

IIRC Artifactory has some support for Docker images, but that seems like a big hammer for this problem. [1]
