[rdo-dev] static container image hosting

Hi folks, At a previous OpenStack Summit, I remember talking to a developer who was working on an application that would host container images. I think the idea was to host everything (or almost everything) as flat files on disk that Apache or nginx could serve directly. (I think this was in the context of undercloud image hosting?). I can't remember the details now, and I can't find any such project with Google. Does this ring a bell with anyone? - Ken
