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.
