I read some more about Docker since posting the parent. The deal-killer for me is that Docker doesn't work on btrfs, and I've been running on btrfs for a while now. Apparently it's actually bugs in the aufs kernel code when using it with a btrfs filesystem. I found a closed issue [1], apparently Docker is currently focusing on refactoring the existing code to have a more extensible plugin-style architecture, and will eventually make a btrfs plugin. That's probably better in the long-run for the project, since it means they won't duplicate work twice, but for right now, it means that my setup isn't supported. Also, support for non-amd64 hosts or guests is highly unsupported and somewhat not-working right now, and networking configuration leaves something to be desired. So I'd say Docker's still really, really immature. [1] https://github.com/dotcloud/docker/issues/443?source=cc https://github.com/dotcloud/docker/issues/443?source=cc
