# ⏰ Kubernetes CronJobs

A **CronJob** in Kubernetes allows you to run jobs on a recurring schedule, similar to traditional UNIX `cron` jobs. Ideal for periodic tasks like backups, reports, or scheduled notifications.

## 🧾 Example CronJob Manifest

This CronJob runs every minute and prints the date followed by "Kubernetes":

```yaml
apiVersion: batch/v1
kind: CronJob
metadata:
  name: cronjob1
  namespace: ns
spec:
  schedule: "* * * * *"
  jobTemplate:
    spec:
      template:
        spec:
          containers:
            - name: cronjob
              image: debian:bookworm
              command:
                - /bin/bash
                - -c
                - date; echo Kubernetes
          restartPolicy: Never
```

> 🛠 **Fix:** Changed `JobTemplate` to `jobTemplate` (YAML keys are case-sensitive).
> 🕐 The `schedule` field follows standard cron format: `minute hour day-of-month month day-of-week`.
> 🧠 **Tip:** Always test cron timing carefully to avoid unintentional frequent runs.
