How do I run a docker instance from a DockerFile?
<p>I finally figured out how to get docker up and running. </p>

<pre><code>docker run --name my-forum-nodebb --link my-forum-redis:redis -p 80:80 -p 443:443 -p 4567:4567 -P -t -i nodebb/docker:ubuntu
</code></pre>

<p>I linked it to a redis instance, cool. </p>

<p>This is from scratch and I assume that when I created the redis instance </p>

<pre><code>docker run --name my-forum-redis -d -p 6379:6379 nodebb/docker:ubuntu-redis
</code></pre>

<p>it pulls the image from a remote repo?</p>

<p>NodeBB offers a <code>Dockerfile</code> <a href="https://github.com/NodeBB/NodeBB/blob/master/Dockerfile" rel="noreferrer">https://github.com/NodeBB/NodeBB/blob/master/Dockerfile</a> I am not really quite sure how to use it. I am assuming that I can somehow create a local environment by calling this Dockerfile on my remote.</p>

<p>Is this correct? If so how can I create the local instance pointing to the remote?</p>
