Docker is restarting again and agin

I'm facing a problem with my docker. I have my own image of SonarQube 3.6.2 which includes a couple a custom rules. I tried to put it in a container, but if I run SonarQube while I'm trying to start my container, then my container keeps on restarting again and again.

I just tried every single idea that I had: ENTRYPOINT (both forms: ENTRYPOINT["/sonarQube362/bin/linux-x86-64/sonar.sh", "start"] and ENTRYPOINT /sonarQube362/bin/linux-x86-64/sonar.sh start), CMD (both forms), using a third party run.sh with these command lines inside:

#!/bin/bash
set -e

#nohup  /sonarQube362/bin/linux-x86-64/sonar.sh start
exec /sonarQube362/bin/linux-x86-64/sonar.sh start

I always have the "Restarting" status on my container and the logs simply complains that Sonar is restarted, again, and again, and again...

If my Dockerfile ends with CMD top for example, then I can docker exec -ti container bash into it and run any of the commands above successfully.

Do you guys have any idea of why, when set as a CMD or an ENTRYPOINT SonarQube/Docker loops restarting?

Cheers,

Solution

OK. I just found the solution.

I updated the sonar.sh script to change the COMMAND_LINE. It used to daemonize the wrapper, I just changed that to NOT daemonize the wrapper. Thus Docker can keep track of it...

For the sake of clarity, here is the line: Before:

#COMMAND_LINE="$CMDNICE \"$WRAPPER_CMD\" \"$WRAPPER_CONF\" wrapper.syslog.ident=$APP_NAME wrapper.pidfile=\"$PIDFILE\" wrapper.daemonize=TRUE $ANCHORPROP $IGNOREPROP $LOCKPROP"

After:

COMMAND_LINE="$CMDNICE \"$WRAPPER_CMD\" \"$WRAPPER_CONF\" wrapper.syslog.ident=$APP_NAME wrapper.pidfile=\"$PIDFILE\" wrapper.daemonize=FALSE $ANCHORPROP $IGNOREPROP $LOCKPROP"

Of course, you may to this using awk or sed while building the Docker image, but that's another topic...

Hope this helps, Cheers, Olivier
