How to Install Docker on Ubuntu 14.04 LTS

Docker is an open-source project that automates the deployment of applications inside software containers, by providing an additional layer of abstraction and automation of operating-system-level virtualization on Linux. Docker uses resource isolation features of the Linux kernel such as cgroups and kernel namespaces to allow independent “containers” to run within a single Linux instance, avoiding the overhead of starting virtual machines.

Here some tips for installing docker on an Ubuntu 14.04 LTS.

Let’s install docker :
apt-get -y install docker.io

Let’s fix link and path :
ln -sf /usr/bin/docker.io /usr/local/bin/docker
sed -i '$acomplete -F _docker docker' /etc/bash_completion.d/docker.io

And finally configure docker to start when the server boot :
update-rc.d docker.io defaults

Of course we search container that contains ubuntu by search token
docker search ubuntu

And we install it
docker pull ubuntu
