Create Countdown Job in Kubernetes

Tasks

• Create a job named countdown-datacenter.

• Name the spec template countdown-datacenter (under metadata), and name the container container-countdown-datacenter.

• Use the image fedora with the latest tag (specify as fedora:latest), and set the restart policy to Never.

• Execute the command sleep 5.

Steps

1. Create a job.yaml manifest file.

    apiVersion: batch/v1
    kind: Job
    metadata:
      name: countdown-datacenter
    spec:
      template:
        metadata:
          name: countdown-datacenter
        spec:
          containers:
          - name: container-countdown-datacenter
            image: fedora:latest
            command: ["sleep", "5"]
          restartPolicy: Never
   

    cat <<EOF > job.yaml
    apiVersion: batch/v1
    kind: Job
    metadata:
      name: countdown-datacenter
    spec:
      template:
        metadata:
          name: countdown-datacenter
        spec:
          containers:
          - name: container-countdown-datacenter
            image: fedora:latest
            command: ["sleep", "5"]
          restartPolicy: Never
    EOF
   

   

2. Apply the manifest file.

    k apply -f job.yaml
   

   

3. Now describe job.

    k describe job
