Verifying the Cronjob

7.4.8 Verifying the Cronjob

Run the following command to make sure the cronjob is created:

kubectl get cronjob -n <namespace>

For example:

kubectl get cronjob -n oudns

The output will look similar to the following:

NAME               SCHEDULE       SUSPEND   ACTIVE   LAST SCHEDULE   AGE
oud-pod-cron-job   */30 * * * *   False     0        5m18s           19m

Run the following command to make sure the job(s) is created:

kubectl get job -n <namespace> -o wide

For example:

kubectl get job -n oudns -o wide

The output will look similar to the following:

NAME                        COMPLETIONS   DURATION   AGE     CONTAINERS        IMAGES                   SELECTOR
oud-pod-cron-job-27586680   1/1           1s         5m36s   cron-kubectl      bitnami/kubectl:1.30.3   controller-uid=700ab9f7-6094-488a-854d-f1b914de5f61

Disabling the Cronjob

If you need to disable the job, for example if maintenance needs to be performed on the node, you can disable the job as follows:

Run the following command to edit the cronjob:
```
kubectl edit cronjob pod-cron-job -n <namespace>
```
For example:
```
kubectl edit cronjob oud-pod-cron-job -n oudns
```
Note:
This opens an edit session for the cronjob where parameters can be changed using standard vi commands.

In the edit session search for suspend and change the value from false to true:

...
schedule: '*/30 * * * *'
successfulJobsHistoryLimit: 3
suspend: true
...

Save the file and exit (wq!).
Run the following to make sure the cronjob is suspended:
```
kubectl get cronjob -n <namespace>
```
For example:
```
kubectl get cronjob -n oudns
```
The output will look similar to the following:
```
NAME SCHEDULE SUSPEND ACTIVE LAST SCHEDULE AGE
oud-pod-cron-job */30 * * * * True 0 7m47s 21m
```
To enable the cronjob again, repeat the above steps and set suspend to false.
