title: Understanding docker port mappings
body: <p>Please explain the following output:</p>
  
  <pre><code>docker ps ExanpleContainter
  
  Ports
  --------
  10.10.10.10:443-&gt;443/tcp, 0.0.0.0:1937-&gt;1937/tcp
  </code></pre>
  
  <p>And, docker inspect ExanpleContainter</p>
  
  <pre><code>"Ports": {
    "1937/tcp": [
      {
        "HostIp": "0.0.0.0",
        "HostPort": "1937"
      }
    ],
    "443/tcp": [
      {
        "HostIp": "10.10.10.10",
        "HostPort": "443"
      }
    ]
  }
  </code></pre>
  
  <p>I'd want to understand how mapping is done and which port is mapped where?</p>
