+# CronJob
+
+1) Создаем CronJob:
+
+```bash
+kubectl apply -f ~/school-dev-k8s/practice/9.oneshot-tasks/2.cronjob/cronjob.yaml
+```
+
+2) Проверяем
+
+```bash
+kubectl get cronjob
+```
+
+Видим:
+
+```bash
+NAME    SCHEDULE      SUSPEND   ACTIVE   LAST SCHEDULE   AGE
+hello   */1 * * * *   False     0        <none>          14s
+```
+
+3) Через минуту пробуем посмотреть на Job'ы
+
+```bash
+kubectl get job
+```
+
+Видим созданный Job
+
+```bash
+NAME               COMPLETIONS   DURATION   AGE
+hello-1552924260   1/1           2s         49s
+```
+
+4) Смотрим на Pod'ы
+
+```bash
+kubectl get pod
+```
+
+Видим Pod
+
+```bash
+NAME                     READY   STATUS      RESTARTS   AGE
+hello-1552924260-gp7pk   0/1     Completed   0          80s
+```
+
+5) Если мы подождем 5-10 минут, то увидим что старые Job'ы и Pod'ы удаляются по мере появления новых
+
+```bash
+kubectl get job,pod
+```
+
+6) Удаляем CronJob
+
+```bash
+kubectl delete -f ~/school-dev-k8s/practice/9.oneshot-tasks/2.cronjob/cronjob.yaml
+```
