Docker Error bind: address already in use : <p>When I run <code>docker-compose up</code> in my Docker project it failes with the following message:</p>

<pre><code>Error starting userland proxy: listen tcp 0.0.0.0:3000: bind: address already in use
</code></pre>

<p><code>netstat -pna | grep 3000</code>
shows this:</p>

<pre><code>tcp        0      0 0.0.0.0:3000            0.0.0.0:*               LISTEN      -  
</code></pre>

<p>I've already tried <code>docker-compose down</code>, but it doesn't help.</p>
