🧾 Example Job Manifest

Here’s a minimal example of a Job that runs a simple echo command:

apiVersion: batch/v1
kind: Job
metadata:
  name: myjob
  namespace: ns
spec:
  template:
    spec:
      containers:
        - name: job1
          image: alpine
          command:
            - echo 
            - "hello world"
      restartPolicy: Never

💡 Note: Always set restartPolicy to Never or OnFailure for jobs. 📌 Jobs are useful for tasks like backups, report generation, or database migrations.
