<li><p>Log into your Ubuntu installation as a user with <code>sudo</code> privileges.</p></li>
<li><p>Verify that you have <code>wget</code> installed.</p>
<pre><code>$ which wget
</code></pre>
<p>If <code>wget</code> isn&rsquo;t installed, install it after updating your manager:</p>
<pre><code>$ sudo apt-get update
$ sudo apt-get install wget
</code></pre></li>
<li><p>Get the latest Docker package.</p>
<pre><code>$ wget -qO- https://get.docker.com/ | sh
</code></pre>
<p>The system prompts you for your <code>sudo</code> password. Then, it downloads and
installs Docker and its dependencies.</p>
<blockquote>
<p><strong>Note</strong>: If your company is behind a filtering proxy, you may find that the
<code>apt-key</code>
command fails for the Docker repo during installation. To work around this,
add the key directly using the following:</p>
<pre><code> $ wget -qO- https://get.docker.com/gpg | sudo apt-key add -
</code></pre>
</blockquote></li>
<li><p>Verify <code>docker</code> is installed correctly.</p>
<pre><code>$ docker run hello-world

Hello from Docker.
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the &quot;hello-world&quot; image from the Docker Hub.
(Assuming it was not already locally available.)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
For more examples and ideas, visit:
http://docs.docker.com/userguide/

<h2 id="where-to-go-next">Where to go next</h2>
<p>At this point, you have successfully installed Docker. Leave the terminal window
open. Then, go onto <a href="/linux/step_two">read a very short explainer Docker images and
containers</a>.</p>
