have used the resin.io docker images on arch on my pi. What I would love is a raspbian version as its just a super popular distro on raspi. I know its a bit of gridlock right now. It seems that its going into the jesse version of debian but the raspbian release of jesse isn't out the last time a checked (a couple weeks ago). I did try out lessbian - awesome name - on raspi and I am not recalling specifically why it didn't work out for me. I had some issue with the filesystem dependencies not being there and getting them was a pretty large undertaking (so much so that it would have been just as easy to do it on raspbian). Would love to contrib myself but right now i'm swamped and don't really have much expertise in either docker or arm. At least my experience should bring some clarity/insight into what I encountered.
