Ubuntu 12 04 Set Docker To Use the LXC Container Engine

As of Docker 0.9, docker does not use LXC by default for the container engine. However, one may find it useful to do so, in order to attach to running containers with a new TTY.

Method 1 - Installation Script

Simply copy the following script into a file and execute it with

#!/bin/bash

# Ensure running bash not sh etc
if ! [ -n "$BASH_VERSION" ];then
 echo "this is not bash, calling self with bash....";
 SCRIPT=$(readlink -f "$0")
 /bin/bash $SCRIPT
 exit;
fi

# Ensure running as root user
USER=`whoami`

if [ "$USER" != "root" ]; then
 echo "You need to run me with sudo!"
 exit
fi

apt-get update && apt-get install lxc -y
echo DOCKER_OPTS="-e lxc" >> /etc/default/docker
service docker restart

Method 2 - Manual Steps

Ensure that you already have LXC installed by running the following command

sudo apt-get install lxc -y

Edit the /etc/default/docker file and adding "-e lxc" as shown below:
Restart the docker service by running
sudo service docker restart
or by rebooting the server
