Kubernetes notes

FAQ
What is the cron expression for the first saturday of every month?
Use `0 0 0 ? * SAT#1` 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.
