Marathon - do not redeploy app when return code = 0?

Question

We have a spring boot application deployed in a docker container and managed using mesosphere (marathon + mesos). The spring boot app is intended to be deployed via marathon, and once complete, it will exit with code = 0.

Currently, every time the boot application terminates, marathon redeploys the app again, which I wish to disable. Is there a setting that I can set in the application's marathon json config file that will prevent marathon from redeploying an app if it does not exit with a non-zero code?

I think there's a principled problem in the understanding of what Marathon does: it is meant for long-running tasks (or put in other words: there's a while loop somewhere in there, maybe an implicit one). If your app exists, Marathon sees this and assumes it has failed and re-starts it again.

If you just want to run one-time jobs, I think Chronos would be the right tool. Marathon is, as Michael wrote, for long-running tasks.
