title: Jboss 5.1 in Dockerfile - how to reach the server in a browser
body: <p>I have a dockerfile which looks like this:</p>
  
  <pre><code>FROM ubuntu:trusty

  EXPOSE 8080
  </code></pre>
  
  <p>i build it than with:</p>
  
  <pre><code>sudo docker build -t dockerfile .
  </code></pre>
  
  <p>everything builds fine. so I start the server with:</p>
  
  <pre><code>sudo docker run -it --publish 127.0.0.1:8080:8080 dockerfile:latest
  </code></pre>
  
  <p>I can see that the server starts correctly</p>
  
  <p>If I enter the URL <code>127.0.0.1:8080</code> i got an error site:</p>
  
  <blockquote>
    <p>the connection was reset - the connection to the server was reset
    while the page was loading</p>
  </blockquote>
  
  <p>How do I get a connection to the server in my browser?</p>
  
  <p>The inspect of my container looks like this:</p>

  <p>EDIT after jottrs answers:
  the logs says:</p>
  
  <pre><code>....

  </code></pre>
  
  <p>nothing more....</p>
  
  <p>because of Jottrs IP mention:
  As far as i understood, I bind my server to <code>127.0.0.1:8080</code> with the start command:</p>
  
  <pre><code>sudo docker run -it --publish 127.0.0.1:8080:8080 dockerfile:latest
  </code></pre>
  
  <p>If I look with ifconfig i have the docker file running on:</p>
  
  <pre><code>$ ifconfig
  docker0   Link encap:Ethernet  Hardware Adresse 56:84:7a:fe:97:99  
            inet Adresse:172.17.42.1  Bcast:0.0.0.0  Maske:255.255.0.0
            inet6-Adresse: fe80::5484:7aff:fefe:9799/64 Gültigkeitsbereich:Verbindung

            RX-Bytes:4983 (4.9 KB)  TX-Bytes:12056 (12.0 KB)
  </code></pre>
  
  <p>But with <code>$ sudo docker inspect --format "{{ .NetworkSettings.IPAddress }}" 054</code>
  i get <code>172.17.0.5</code></p>
  
  <p>But I also get no connection in my browser with the URL <code>172.17.0.5:8080</code>  or URL <code>172.17.42.1:8080</code></p>
  
  <p>also if I start with <code>$ sudo docker run -d --publish 172.17.42.1:8080:8080 dockerfile:latest</code> (the ifconfig IP) I will not get a connection (and still no reaction on the logs)</p>
  
  <pre><code>$ sudo docker exec -it 228 bash
