Well I did not try to use bluetooth from a container yet, but did you run those containers with '--privileged' as part of the docker run command?

Your shared library assertion is incorrect, at least on Intel machines. See Solomon Hykes' reply on this thread: https://groups.google.com/forum/m/#!msg/docker-user/wCDC_sXz...
"... Moving the Node apps to run under plain Arch Linux systemd made the Pies noticeably more reliable and efficient. ..."
Docker is interesting to look at because if you have N IoT devices, deployment becomes the problem.

After Docker 1.5 is out... anybody interested in a new Raspberry Pi 2 compatible image?
Yes please!, Thank you very much.
On top of that, it would be awesome if you could release the repo with the source, makefiles and stuff...

Get the most recent Docker working on your Raspberry Pi in no time at all. See what is already possible with such tiny device.
Love to hear your feedback!

How future-proof is this? i.e., where do we get updates from?
(if there aren't any extra APT repos, is there a source tree/recipe to upgrade to later versions?)

Currently this is more of an experiment to see if it is possible to get Docker running. The image is based on Raspbian with a custom kernel compiled for working with Docker and OverlayFS. We will publish our buildscript within a couple of days on github. Based on the feedback we get we want to provide updates to the image on a regular base.
Thanks. I would very much like to see that buildscript - I've been tinkering with the idea of building something along these lines but with an Ubuntu armhf userland (given that Ubuntu on ARM has a lot of advantages for me).
- You can't access some things from inside containers, e.g. Bluetooth LE.
- Processes that run in separate containers don't use shared libraries (shared RAM) so they weigh more. At least I believe so.
I recently built 5 Raspberry Pis for IoT data collection purposes, and they were slow and unreliable when running multiple Node.js apps in Docker containers. Moving the Node apps to run under plain Arch Linux systemd made the Pies noticeably more reliable and efficient.
