Create a repeatable Job

Users can also decide the number of tasks that should be finished in a single Job. It is helpful to solve some random and sampling problems. Let's try it on the same template in the previous example:

1. Add the spec.completions item to indicate the Pod number:

$ cat job-dpkg-repeat.yamlapiVersion: batch/v1kind: Jobmetadata:  name: package-checkspec:  completions: 3  template:    spec:      containers:      - name: package-check        image: ubuntu        command: ["dpkg-query", "-l"]      restartPolicy: Never

2. After creating this Job, check how the Pod looks with the subcommand kubectl describe:

$ kubectl create -f job-dpkg-repeat.yaml job.batch "package-check" created$ kubectl describe jobs package-checkName:           package-checkNamespace:      default...... ...
