# GETTING STARTED

Docker is still under heavy development. It should not yet be used in production. Check the repo for recent progress.

## Installing on Ubuntu

Requirements

- Ubuntu 12.04 (LTS) (64-bit)
- or Ubuntu 12.10 (quantal) (64-bit)

1. Install dependencies

   The linux-image-extra package is only needed on standard Ubuntu EC2 AMIs in order to install the aufs kernel module.

       sudo apt-get install linux-image-extra-`uname -r`

2. Install Docker

   Add the Ubuntu PPA (Personal Package Archive) sources to your apt sources list, update and install.

   You may see some warnings that the GPG keys cannot be verified.

       sudo sh -c "echo 'deb http://ppa.launchpad.net/dotcloud/lxc-docker/ubuntu precise main' >> /etc/apt/sources.list"

       sudo apt-get update

       sudo apt-get install lxc-docker

3. Run!

       docker run -i -t ubuntu /bin/bash

Continue with the Hello world example.
