Periodic Job

Our Cron Job example builds on top of the Batch Job example above, to the basic setup is the same:

A Minikube installation available, ideally with Minikube
Minikube started with minikube start --mount --mount-string="$(pwd)/logs:/example" to mount the local logs/ into the Minikube VM

Then create the PersistentVolume and PersistentVolumeClaim with

kubectl create -f pv-and-pvc.yml

but you don’t have to do it, if you already have your Minikube still running from the Batch Job example ^[1]

Now create the CronJob which fires every three minutes:

kubectl create -f cron-jobs.yml

In this example we only use only one completion per Job (i.e. the default for a Job).

You can check the logs/random.log for the numbers generated, and also of course the Pods that are run on behalf of the job.

1. If you reuse the Batch Job example, don’t forget that the random.log is generated in the logs/ directory over there.
