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
- "Monthly cron schedules are calendar-based
- not fixed 30-day intervals."
- Combining day-of-month and day-of-week in standard cron can create unexpected extra runs.
FAQ
What is the cron expression for monthly on day 23?
Use `0 0 23 * *` 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.
