[ringtail]

Could you explain what is cron mode.

[LivingCcj]

cronMode : controller cron job work or not work. Enable: means cron job is work normal. Disable: means cron job is not work (set cron mode when upgrade service or stop cronhpa but not delete it).

What's is the scene？

[LivingCcj]

base scene : cronhpa -> deployment when you upgrade deployment, the cronhpa will attack the upgrade operation, so it should skip this cron job. meanwhile cronhpa -> hpa -> deployment

when you upgrade deployment, the cronhpa will attack the upgrade operation, so it should skip this cron job.

Do you mean cronhpa is in a very tiny duration?

if deployment type is Rolling update，cron job will disturb the procedure of rolling. there would take some risk

Would skip this time and retry later be better for this case?
