Kubernetes notes
- Kubernetes CronJobs use standard five-field cron syntax.
- "Set concurrencyPolicy
- restartPolicy
- and history limits based on expected runtime and failure behavior."
Common mistakes
- Forgetting to confirm which timezone the scheduler uses.
- Assuming the schedule starts relative to deployment time instead of matching wall-clock fields.
FAQ
What is the cron expression for every day at 03?
Use `0 3 * * *` for standard cron when the scheduler supports this syntax.
Can I use this expression in Kubernetes?
Yes, if it is standard five-field cron. AWS and Quartz-only operators need a Kubernetes-safe alternative or application-level date logic.
