This is a dumb-dumb script I cobbled together to provision an IPXCore KVM (Ubuntu 13.10 x64) to run Docker containers. It'll probably work in a lot of other contexts.

You have root access to a running VM somewhere.

Connects to a bare VM and installs Docker on it.

• Connect to host, create user account, upload SSH keys, upload a script (which performs the remainder of the provisioning)
• Install and run Docker, bind Remote API to loopback port
• Use SSH tunnelling to talk to Docker daemon on the newly provisioned box.

Now you can run Docker containers on a VM. Go crazy.

Do these things:

• Provision the VM:

  $ HOST=<host> provision.sh

• Create an SSH tunnel to the inner Docker daemon:

  ssh -L 4243:<host>:4243

• Now you can run containers remotely:

  DOCKER_HOST=<host> docker run …

Provisioning create an account for you (sudoer, NOPASSWD) and add your public key to authorized_keys on the base VM. Then it copys and runs provision_box.sh as you to install and run the Docker daemon.
