title: Process owner of a docker program
body: <p>I have started an <code>nginx</code> container bound on the <code>host</code> network as follows:</p>
  
  <pre><code>docker run --rm -d --network host --name mynginx nginx
  </code></pre>
  
  <p>However, when querying process information with the <code>ss</code> command, this seems to be a pure <code>nginx</code> but <strong>not</strong> a <code>docker</code> process:</p>
  
  <pre><code>$ ss -tuap 'sport = :80'
  Netid               State                  Recv-Q                 Send-Q                                  Local Address:Port                                 Peer Address:Port                
  tcp                 LISTEN                 0                      128                                           0.0.0.0:http                                      0.0.0.0:*                    users:(("nginx",pid=16563,fd=6),("nginx",pid=16524,fd=6))
  </code></pre>
  
  <p>why is that?</p>
