kubernetes cronjob scheduling yaml

I need help solving I've been banging my head against this for hours. I'm having trouble with my Kubernetes CronJob that seems to not be creating pods at the scheduled intervals I defined. I have a CronJob defined like this: ```yaml apiVersion: batch/v1beta1 kind: CronJob metadata: name: my-cronjob spec: schedule: "*/5 * * * *" jobTemplate: spec: template: spec: containers: - name: my-container image: my-image:latest command: ["/bin/sh", "-c", "echo Hello from the CronJob!"] restartPolicy: OnFailure ``` The intention is to run this every 5 minutes, but I noticed that it rarely creates the pods as expected. I checked the logs for the CronJob and found this output: ``` behavior creating job: the cron job "my-cronjob" is invalid: spec.jobTemplate.spec.template.spec.restartPolicy: Invalid value: "OnFailure": must be one of [Always Never] ``` I assumed the scenario was with the `restartPolicy`, but I’ve checked the documentation for Kubernetes v1.22, and it states that `OnFailure` should be valid for job templates. I even tried changing the `restartPolicy` to `Always`, but the pods still don’t execute as scheduled. I've also ensured that the cluster’s time zone is correct using the `kubectl get nodes -o wide` command, and everything looks aligned with the UTC configuration. I've tried redeploying the CronJob after making changes, but each time, the behavior remains the same. I would appreciate any insights on what might be going wrong. Is there something specific about how CronJobs handle timing or scheduling that I might be missing? For context: I'm using Yaml on Linux. Any help would be greatly appreciated! I'm working in a Linux environment. Any ideas how to fix this?
