What is CKAD?
CKAD is a comprehensive certification that includes a 100% hands-on exam to provide assurance that CKADs have the skills, knowledge, and competency to perform the responsibilities of Kubernetes.
It certifies the ability of a developer to build, configure, design, and expose native cloud applications for Kubernetes. Such developers are further able to work with core resources to build, monitor, and troubleshoot applications in Kubernetes.
CKAD (Certified Kubernetes Application Developer) is developed by the Cloud Native Computing Foundation (CNCF) with The Linux Foundation. While Kubernetes was originally designed by Google, and now maintained by CNCF.
CKAD is one of the difficult exams to pass but you can be a Certified Kubernetes Application Developer (CKAD) in just 33 days, IFF – If and only If you follow guidelines properly.
How to pass the Certified Kubernetes Application Developer (CKAD) Exam?
If you have an adequate amount of knowledge on Docker, containers, and microservices architecture and an intermediate hands-on Linux.

KEY Concepts for CKAD:
- Start with basics

- Group 1 –> Debugging Kubernetes, Pods, Deployments, Jobs, Services, editing YAML, Volumes and PVCs, namespaces, labels
- Group 2 –> Liveness and readiness, logging, monitoring, multi-container pods, rolling updates and rollbacks
- Group 3 –> Service Accounts, resource quotas, security contexts
- Write YAMLs of all resources at least thrice!
- Create resources using descriptive commands
- Practice, practice, again practice then again practice!!
- Attempt Mock
