Exercise 4.3: Designing Applications With Duration: Create a CronJob

1. CronJob 생성

   cat <<EOF | kubectl create -f -
   apiVersion: batch/v1
   kind: CronJob
   metadata:
     name: sleepy
   spec:
     schedule: "*/1 * * * *"
     jobTemplate:
       spec:
         template:
           spec:          
             containers:
             - name: resting
               image: busybox
               command: ["/bin/sleep"]
               args: ["3"]
             restartPolicy: Never
   EOF

2. 생성된 CronJob 상태 확인

   kubectl get cronjob sleepy

3. Job 목록 확인

   kubectl get job

4. Pod 목록 확인

   kubectl get pod

5. CronJob 삭제

   kubectl delete cronjob sleepy

6. CronJob 생성

   cat <<EOF | kubectl create -f -
   apiVersion: batch/v1
   kind: CronJob
   metadata:
     name: sleepy
   spec:
     schedule: "*/1 * * * *"
     jobTemplate:
       spec:
         template:
           spec:
             activeDeadlineSeconds: 10          
             containers:
             - name: resting
               image: busybox
               command: ["/bin/sleep"]
               args: ["30"]
             restartPolicy: Never
   EOF

7. 생성된 CronJob 상태 확인

   kubectl get cronjob sleepy

8. Job 목록 확인

   kubectl get job

9. CronJob 삭제

   kubectl delete cronjob sleepy
