Package into Docker Container

[cbun]

Install Docker

http://docs.docker.com/installation/

As root, in GNU Screen (so we can stop the container from another shell)

screen
sudo su

Pull Compute Image from Repository

$ docker pull 10.0.28.9:8000/assembly:compute

Check if image pulled

$ docker images
REPOSITORY                     TAG                 IMAGE ID            CREATED             VIRTUAL SIZE

Create temporary virtual /mnt/data in the image and run

$ docker run -v /mnt/data 6974d25316ad /bin/sh -c "cd /home/assembly/lib/assembly; ./ar_computed.py -s 10.0.28.15 -c ar_compute.conf"

Added you guys to the docker group on SAL. If you log back in, non-root docker commands should work.

The image size keeps growing. There's some discussion on flattening docker images. I don't see a good solution yet. https://github.com/dotcloud/docker/issues/332
