Jobs

Jobs are a fundamental resource type in Kubernetes used to run batch processes that run to completion. Unlike long-running services such as web servers, jobs are intended to terminate when the batch process finishes.

A job creates one or more pods that run a defined workload and then terminates when the workload is complete. This is useful for tasks such as data processing, machine learning training, or any finite computation.

To create a job, you define a Job resource in a YAML manifest like this:

job.yaml

apiVersion: batch/v1
kind: Job
metadata:
    name: myjob
spec:
    template:
    spec:
      containers:
      - name: myjob
        image: busybox
        command: ['sh', '-c', 'echo Hello Kubernetes! && sleep 30']
  ...
