How To Install Docker on Ubuntu 14.04

Install Docker on Ubuntu 14.04

In this tutorial, we will show you how to install Docker on Ubuntu 14.04. For those of you who didn’t know, Docker is an open-source tool that makes creating and managing Linux containers (LXC) easy. With Docker, the applications reside inside the container on top of the Linux operating system. Docker uses Kernel features such as groups and namespace to allow the independent containers to run on a single os instance.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you the step-by-step installation of Docker on Ubuntu 14.04.


  • A server running one of the following operating systems: Ubuntu 14.04.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Docker on Ubuntu 14.04

Step 1. First of all, make sure that all packages are up to date.

apt-get update
apt-get upgrade

Step 2. Install Docker using the apt-get command.

apt-get install

Start and enable Docker service:

service status
service start

Create a symlink to the Docker executable so that the Docker documentation commands can be executed without changing the path. This is required because the Ubuntu package for Docker is installed to a different directory to the default Docker recommendation:

ln -sf /usr/bin/ /usr/local/bin/docker
sed -i '$acomplete -F _docker docker' /etc/bash_completion.d/

Step 3. Download a Docker Container.

Let’s begin using Docker, Download the ubuntu Docker image:

docker pull ubuntu

Step 4. Run a Docker Container.

As we can see ubuntu container has been started and we got the bash shell. In the docker command, we have used options like ‘-i attaches stdin and stdout’ and ‘-t allocates a terminal or console’. Once you exit the shell, the Docker image will be switched off.

docker run -i -t ubuntu /bin/bash

Alternatively, you may want to launch a specific version of Ubuntu: a container that can contain multiple images. This command shows the available images that you have downloaded so far:

sudo images
REPOSITORY          TAG                 IMAGE ID
ubuntu              vivid               76ca2fd90787
ubuntu              15.04               76ca2fd90787
ubuntu              utopic              cfaba6b5fefe
ubuntu              14.10               cfaba6b5fefe
ubuntu              14.04               5ba9dab47459
ubuntu              trusty              5ba9dab47459
ubuntu              14.04.1             5ba9dab47459
ubuntu              latest              5ba9dab47459
ubuntu              12.04.5             69c02692b0c1

Now if you want to launch another version, you can simply prepend the TAG of the version you want to launch to the container in this way:

sudo run -i -t ubuntu:14.10 /bin/bash
