Description

Pods are the basic unit of work in Kubernetes. This Lab begins by teaching you basic Pod design including how to use labels to define sets of Pods. After that, you will learn to design Pod workloads using higher-level resources in Kubernetes that simplify Pod management. You will use Deployments to manage long-running workloads and perform rolling updates and rollbacks between versions of an application. You will also learn how to use Jobs and CronJobs to manage batch workloads that run to completion.

This Lab is valuable to anyone working with Kubernetes, but the content has been prepared considering topics described in the Certified Kubernetes Application Developer (CKAD) Exam Curriculum. Completion of the Lab will help you get hands-on experience, which is essential for passing the CKAD exam.
