Ok, so no - diskimage-builder builds regular OpenStack full disk disk images.
Translating that to a filesystem is easy; doing a diff against another filesystem version is also doable, and if the container service for Nova understands such partial container contents you could certainly glue it all in together, but we don't have any specific glue for that today. I think docker is great, and if the goal of solum is to deploy via docker, I'd suggest using docker - no need to make diskimage-builder into a docker clone. OTOH if you're deploying via heat, I think Diskimage-builder is targeted directly at your needs : we wrote it for deploying OpenStack after all. -Rob On 24 November 2013 12:24, Adrian Otto <adrian.o...@rackspace.com> wrote: > > On Nov 23, 2013, at 2:39 PM, Robert Collins <robe...@robertcollins.net> > wrote: > >> On 24 November 2013 05:42, Clayton Coleman <ccole...@redhat.com> wrote: >> >>>> Containers will work fine in diskimage-builder.
