title: FTP does not work from mesos docker container
body: <p>I have scala application with akka steams. So the flow of my application is like this:</p>
  
  <pre><code>1. Check if file exists on FTP - I'm doing it with the org.apache.commons.net.ftp.FTPClient
  2. If it exists stream it via alpakka library(and make some stream transformations)
  </code></pre>
  
  <p>My application works locally and it can connect to the server.</p>
  
  <p>The problem is when it is being deployed to dcos/mesos. I get an issue:</p>
  
  <pre><code>java.io.IOException: /path/file.txt: No such file or directory
  </code></pre>
  
  <p>I can say for sure that file still exists there. Also when I try to connect from docker container locally through the ftp I've got something like this: </p>
  
  <pre><code>ftp&gt; open some.ftp.address.com
  Connected to some.ftp.address.com.
  220 Microsoft FTP Service
  Name (some.ftp.address.com:root): USER
  331 Password required

  Remote system type is Windows_NT.
  ftp&gt; dir
