Sonar:6.7 docker container restart loop

I am running an init.sh script in order to create mapped directories for Sonar and Postgres.

Both of the containers build fine and are able to be started, but for some reason, our Sonar container is in a constant restart loop after about 8-16 seconds.

In the logs we noticed that there was a missing plugin error for "findbugs", although the compability matrix states that findbugs works with Sonar 6.7.

2017.11.23 17:16:21 WARN  web[o.a.c.l.WebappClassLoaderBase] The web application [ROOT] appears to have started a thread named [Timer-0] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:
     java.lang.Object.wait(Native Method)
     java.util.TimerThread.mainLoop(Timer.java:552)
     java.util.TimerThread.run(Timer.java:505)

This seems to be a popular error when I do a sudo docker logs sonar_container

Restarting:

```

I ran into the same issue and found this docker-compose file that is able to start postgres and sonarqube.
