In case this will be helpfull for someone here [1] is my Docker
file for building GHC-7.10.3 on Debian Wheezy from sources, also
here is the image itself [2]. Note, Docker Hub shows that image
size is 1Gb, however running `docker images` locally shows me
6.354 GB. I tried to make some cleanup but my docker skills are
quite weak, so I will be happy if anyone can teach me how to
reduce image size.

For the Haskell Platform I did the build on Debian Jessie using docker. I haven't tried to share the images, but I worked from these notes: https://github.com/haskell/haskell-platform/blob/master/notes/building-ghc-docker

That was the first time I ever used docker. Perhaps in the future we can combine efforts to reduce duplication? I've been trying to figure out if we can use this setup to cross compile a 32bit build as well, but it seems like 32bit containers are not supported. I think for a cross compile that true 32bit support is unnecessary so I'm not quite ready to give up on the idea.

Thanks,
