Re: [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?
This is what we do on the tripleo undercloud using the image-serve
service[0]. We have python code that extracts the layers out and
writes it to disk[1][2] which makes it effectively a read only
registry. Though the amount of code to do all this is terribly
complex and I wouldn't recommend doing it for anything else. If you
can use the docker-registry via a container[3], that'd likely be a
better solution if you can (though may not be possible for various
reasons).
