Job与Cronjob 示例

Job基本用法（更多详细的用法可以使用explain查看）

apiVersion: batch/v1
kind: Job
metadata:
  name: test-job
  labels:
    group: jobexample
spec:
  completions: 5
  parallelism: 2
  template:
    metadata:
      labels:
        app: myjob
    spec:
      containers:
      - name: busybox
        image: busybox
        command: ['/bin/sh', '-c', 'sleep 10']
      restartPolicy: Never

其中，completions为任务总数；parallelism为并发执行的个数

2、CronJob的坑
由于Pod默认时间使用的是UTC，所以当你设置定时任务时，时间必须为当前时间减去8

apiVersion: batch/v1beta1
kind: CronJob
metadata:
  name: test-cronjob
  labels:
    group: cronjobexample
spec:
  schedule: "*/5 5 * * *"
  jobTemplate:
    spec:
      completions: 5
      parallelism: 2
      template:
        metadata:
          labels:
            app: myjob
        spec:
          containers:
          - name: busybox
            image: busybox
            command: ['/bin/sh', '-c', 'sleep 10']
          restartPolicy: Never
