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.
