Sorry for the very late response!

Running shepherd via cron is a good idea. I find this approach using crond a bit ugly but I guess it's the easist way to do this cross-platform..

Wondering if it is the right way to handle it inside shepherd.
Maybe it would be better to have an option to run only once and not loop every 5 minutes, and leave the scheduling to a specialised tool like https://github.com/crazy-max/swarm-cronjob ?

in relation to my previous comment, I just discovered the option RUN_ONCE_AND_EXIT exists already. IIUC together with https://github.com/crazy-max/swarm-cronjob (which I'm using successfully for db backups) it does provide the functionality of this PR.

@rbauduin You are absolutely right. I am using that approach all the time but somehow this thought did not come to my mind when looking at this PR.

I would go even further and say the usage of swarm-cronjob should be the recommended approach of using shepherd. I guess we should adjust the README accordingly.

@shizunge Very sorry for the delay and everything, but with the above said it does not make sense to merge this PR.
