Cronjobs

Unlike Deployments and StatefulSets—which are designed to keep long-running processes alive indefinitely—Jobs and CronJobs are designed for run-to-completion batch tasks. When the workload process terminates with exit code 0, Kubernetes marks the Pod as Completed.

The Certified Kubernetes Application Developer (CKAD) exam tests your ability to design, build, expose, and troubleshoot cloud-native applications running inside Kubernetes clusters.
