Can you tell us why cronjob is used instead of starting manually?
A cronjob can be useful for recurring "jobs". If you want to run automatically a program which retrieve images and export them in PDF, for example, it's possible in a cronjob. You can schedule the cronjob.
I mean, why run Kubernetes cronjobs? Why not just start it manually? Is it just to automate some task by invoking a pod?
It's for automated tasks yes.
A cronjob scheduled every 10 minutes, will spawn a new pod every 10 minutes.
If a pod failed, you can watch the logs, analyze and understand why this case has failed.
