Better to add an enabled flag as we have for everything else?

I considered that, but in other cases when
enabled: falseis set we don't render the template. However, in this case it means theCronJobis not defined and not available to be run manually. By setting the schedule to a time that never occurs theCronJobis defined and is available to be run manually if desired. At least that was my thought process.There was a problem hiding this comment.

Reading more about cron jobs, maybe I should be using
.spec.suspendhere. I'll play around with that and see if I get the desired behavior.There was a problem hiding this comment.

Good idea to investigate suspend. Maybe we should add both. Some instructions on how to manually invoke the cronjob would also be useful.

Using
.spec.suspendlooks to be less than ideal, particularly if one wants to run the job once but keep it suspended. In that case the user must:.spec.suspend=false.spec.suspend=trueGiven users can always disable a cron job with the
scheduleI am not sure.spec.suspendis worth it.There was a problem hiding this comment.

I think that adding an enabled flag would still be useful. Users who want to run the cronjob manually can still use the trick you suggested. Just that it feels weird to have to think of an invalid date for the simplest case of not wanting the cron job.
