Just to clarify on the OSX support: obviously we did not magically get Darwin to support linux containers. But we put together the easiest possible way to run Linux containers on a Mac without depending on another machine. We do this by combining (1) docker in "client mode", which connects to (2) a super-lightweight linux VM using boot2docker. The details are on http://docs.docker.io/en/latest/installation/mac/

Note that you need to be running boot2docker 0.5.2 [1] (with docker 0.8) for docker to work properly on OS X.

Too bad it depends on VirtualBox - had a lot of kernel panics when using it, so I decided to stick with VMware fusion.

You should be able to install the same iso into a VMware image. You'll need to expose the networking ports, but the information should be in the boot2docker script.

It is especially important to set DOCKER_HOST=tcp:/// before you run "boot2docker init" -- I forgot to do this initially and things failed mysteriously. I had to "boot2docker delete" and re-init to get things running.

Once I got that ironed out, everything is running very smoothly, and I don't have to ssh into the VM to do things. Nicely done.

My wish for 0.9 is a more streamlined installation process, possibly by simply incorporating these steps into a Homebrew formula.

Note that this is documented in the boot2docker README ;)

I'm curious about how the focus on multiple, ABI-incompatible platforms will affect the pace and momentum of Docker development. So far, Docker has benefitted a lot from the focus on amd64 userland on Linux.

Docker on OSX is actually running on a lightweight Linux VM, so it's not really multi-platform support they've added.
