Access Wildfly-Docker-Container from Apache-Docker-Container
<p>to test my web-application I am building a Docker-Setup.
In one container an apache is running on which the PHP-Frontend is deployed, another container has the wildfly with the actual application running (java .war-file) and a third container has a Postgresql-DB that holds the application's data.</p>

<p>When I am trying now to access the frontend through a browser I receive an exception and it tells me that the wildfly refused the connection.<br>
    fopen(<a href="http://172.17.0.3:8080/[...]" rel="nofollow">http://172.17.0.3:8080/[...]</a>): failed to open stream: Connection 
refused<br>
I am pretty much out of ideas now and would be rather thankful for every input I can get. I dont really think anyone knows the perfect answer, but maybe I can receive some ideas that get me onto the right track.</p>

<p>So is this due to the wildfly-setup ?
Some authentication problem between the containers ?</p>

<p>Thanks in advance</p>
