You can use use base containers I built if you want: https://hub.docker.com/r/zeldin/debian/tags
They are built using debuerreotype, so they should be identical to Debian built ones. There's also another guy making base containers for ppc64 and some other arches (including 32-bit ppc): https://hub.docker.com/r/paleozogt/debian/tags but those are a little old.
