Kubernetes CronJob - Skip job if previous is still running AND wait for the next schedule time

Question

I have scheduled the K8s cron to run every 30 mins.

If the current job is still running and the next cron schedule has reached it shouldn't create a new job but rather wait for the next schedule.

And repeat the same process if the previous job is still in Running state.

Answer 1

set the following property to Forbid in CronJob yaml

.spec.concurrencyPolicy
