 <p>I am not sure if I understand you correctly but if you want to deploy applications on different ports, when launching your application, you can pass the port on the command line and do</p> <pre><code>./activator start -Dhttp.port=yourDynamicPort </code></pre> <p>as Kris suggests you can do </p> <pre><code>-Dhttp.address=yourIP </code></pre> <p>to assign address</p>
