Configuring CronJobs in Kubernetes
Pods are not the only way to run workloads in Kubernetes. You can also use jobs to execute something once, or you can use cron jobs to execute workloads on a schedule. This lab provides an opportunity to learn about cron jobs by implementing a simple scheduled job in a working Kubernetes cluster.
Table of Contents
Create the cron job in the cluster
Create a descriptor for the cron job with
apiVersion: batch/v1beta1 kind: CronJob metadata: name: cleanup-cronjob spec: schedule: "*/1 * * * *" jobTemplate: spec: template: spec: containers: - name: data-cleanup image: linuxacademycontent/data-cleanup:1 restartPolicy: OnFailure
Create the cron job in the cluster.
kubectl apply -f ~/cleanup-cronjob.yml
Allow the cron job to run successfully
Give the cron job a minute or so to run once, and then check the status.
kubectl get cronjob cleanup-cronjob
You should see a timestamp under
LAST-SCHEDULE, indicating the job was executed.
