Kubernetes Observability: Monitoring, and Debugging
An important consideration for any platform used to deploy production applications is observability. This Lab essentially answers how Kubernetes handles and helps you with observing everything that happens in the platform in terms of monitoring. Logging and monitoring are two pillars of observability. You will use what is built into Kubernetes and
kubectl as well as how to extend the platform to use external monitoring systems. More specifically, you will use Metrics Server as an example of a monitoring system. These foundations give you powerful debugging skills to diagnose and resolve issues with applications running in Kubernetes.
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.
