[A-00241] Kubernetes 1000本ノック (5)

前回投稿はこちら

今回はKubernetest Jobを使ってみたいと思います。

とりあえず簡単なJobから作ってみます。

apiVersion: batch/v1
kind: Job
metadata:
  name: test-job
  labels:
    app: test-job
spec:
  template:
    metadata:
      labels:
        app: test-job
    spec:
      containers:
      - name: busybox
        image: busybox:latest
        command: [ "sh", "-c", "sleep 5; exit 0" ]
      restartPolicy: Never
  completions: 6
  parallelism: 2

上記をapplyして実行結果を確認します。
