How to trigger a Kubernetes cronjob

2 min read

If you deploy a Cronjob on Kubernetes it can be useful to test it out by manually triggering a run rather than to wait until it is run according by it's schedule.

Let's assume we have the following Cronjob that we want to run:

$ kubectl get cronjob
NAME                    SCHEDULE    SUSPEND   ACTIVE   LAST SCHEDULE   AGE
pet2cattle-sitemapgen   0 5 * * *   False     0        <none>          13m

The cronjob object haven't been GA until Kubernetes v1.21, even though the Job object have been GA for a long time. Let's take a look how it works:

$ kubectl create job demo --image nginx --dry-run=client -o yaml  | head -n1
apiVersion: batch/v1
$ kubectl create cronjob demo --image nginx --schedule="*/1 * * * *" -o yaml --dry-run=client | head -n1
apiVersion: batch/v1beta1
