title: Docker - Cassandra with Authentication
body: <p>I want to setup a Cassandra container with configured authentication on Docker. Currently i'm using the <a href="https://hub.docker.com/_/cassandra/" rel="nofollow">official Cassandra Docker image</a>, but it doesn't seem to provide a option (via the ENV thingies) for enabling Auth Mode. </p>
  
  <p>One possibility would be to setup an own repository, clone from the Cassandra Docker GitHub and modifiy <a href="https://github.com/docker-library/cassandra/blob/9062e0160e3a24ec0acb368c69d85153a43bfdb1/3.0/docker-entrypoint.sh" rel="nofollow">this file</a> so it also accepts the Auth related options, but this seems a bit to complex for my quite simple task. Does anybody know about a more simple solution or has any hints?</p>
