CKAD Certified Kubernetes Application Developer Crash Course

If you are passionate about Kubernetes and want to take your career to the next level, then taking the Certified Kubernetes Application Developer (CKAD) certification will help to achieve the goal.

The role of Certified Kubernetes Application Developer is to declare application resources and use elemental primitives to build, monitor, and troubleshoot scalable applications and tools in Kubernetes.

This learning path is designed in such a way that it covers all important modules in a detailed manner with the perfect combination of theoretical concepts and practical exercises that will help you to get prepared for CKAD certification. 

This certification consists of seven modules:

• Core Concepts - 13%

• Multi-container pods - 10%

• Pod design - 20%

• Configuration - 18%

• Observability - 18%

• Services and networking - 13%

• State persistence - 8%

In the core concepts modules, you will learn about pods (the basic component of Kubernetes), namespaces (virtual clusters), services (exposing objects to the external world), and much more.

In multi-container pod modules, you will learn how to create and run multiple containers inside single pod. Also learn how to create communication among the containers. Also cover the concepts of the sidecar and adapter patterns.

In the Pod design module, you will learn about labels, replica controllers, replica set and deployments. Then how to create high availability and auto-scaling applications, then how to do easy updates and quick rollbacks with different deployment strategies. 

In the configuration module, you will learn and create config-map and secrets to pass environment variables, sensitive data and much more into running pod. Also learn about service accounts.

In the Observability module, you will learn how to check and monitor the health of running pods using liveness and readiness probes. Also learn how to debug and check the log of the pod.

In the services and networking module, you will learn about ClusterIP, NodePort, and LoadBalancer. And how to expose Kubernetes objects to the external world.

In the state persistence module, you will learn how to make a statefulness application and create persistent volumes and persistent volume claims for storage.

This course will make a strong foundation on Kubernetes and related objects to help you to clear CKAD certification and boost your career to the next level.
