CKAD Certification: Validating Your Kubernetes Skills
The Certified Kubernetes Application Developer (CKAD) certification is a prestigious credential offered by the Cloud Native Computing Foundation (CNCF) through the Linux Foundation. It validates a candidate's ability to design, build, and deploy cloud-native applications for Kubernetes. At DevsOperative, we believe that the CKAD certification is an excellent starting point for professionals new to Kubernetes.
Navigating the Recent PSI Exam Changes
The CKAD exam has recently undergone several changes, most notably in the proctoring process. The exam is now proctored using the PSI browser, which means that multiple monitors are no longer allowed, and candidates must ensure they are using the largest screen possible. Additionally, the check-in process has been updated, and candidates are given an additional 15 minutes to check-in before they are matched with a proctor.
Understanding the CKAD Exam Content
The CKAD exam covers a wide range of topics, all of which are crucial to effectively designing, building, and deploying applications for Kubernetes. These topics include:
- Application Design and Build: This section focuses on defining, building, and modifying container images, understanding Jobs and CronJobs, understanding multi-container Pod design patterns, and utilizing persistent and ephemeral volumes.
- Application Deployment: This section covers the use of Kubernetes primitives to implement common deployment strategies, understanding Deployments and how to perform rolling updates, and using the Helm package manager to deploy existing packages.
- Application Observability and Maintenance: This section delves into understanding API deprecations, implementing probes and health checks, using provided tools to monitor Kubernetes applications, utilizing container logs, and debugging in Kubernetes.
- Application Environment, Configuration, and Security: This section explores discovering and using resources that extend Kubernetes (CRD), understanding and defining resource requirements, limits and quotas, understanding ConfigMaps, creating and consuming Secrets, understanding ServiceAccounts, and understanding SecurityContexts.
- Services & Networking: This section demonstrates a basic understanding of NetworkPolicies, providing and troubleshooting access to applications via services, and using Ingress rules to expose applications.
