Application Observability and Maintenance for CKAD
Prepare for the CKAD observability domain by learning to handle API deprecations, use CLI tools to monitor and debug apps, view container logs, and implement probes and health checks to keep your Kubernetes workloads healthy and responsive.
What you'll learn
Running Kubernetes applications reliably requires deep insight into what’s happening inside your pods—and the ability to respond quickly when things go wrong. In this course, Application Observability and Maintenance for CKAD, you’ll gain the practical skills required to observe, troubleshoot, and maintain containerized applications running on Kubernetes. First, you’ll learn how to work with Kubernetes API deprecations, ensuring your manifests remain compatible with current and future versions. Next, you’ll explore how to implement and test health probes like liveness, readiness, and startup checks to improve the stability and resilience of your applications. Then, you’ll use built-in CLI tools to monitor and investigate your workloads. Finally, you’ll practice interpreting container logs, viewing events, and performing hands-on debugging for common failure scenarios. When you’re finished with this course, you’ll have the knowledge and command-line experience needed to confidently tackle observability and maintenance tasks on the CKAD exam—and in real-world Kubernetes environments.
