Introduction
The Certified Kubernetes Application Developer (CKAD) is a globally recognized certification focused on designing, building, and deploying applications on Kubernetes. It validates hands-on skills required to work with Kubernetes in real-world production environments.
What it is
CKAD is a practical, performance-based certification that tests your ability to design, build, configure, and expose cloud-native applications using Kubernetes. It focuses on real-world tasks rather than theoretical knowledge.
Who should take it
- Developers working with containerized applications
- DevOps Engineers managing Kubernetes workloads
- Cloud Engineers and Platform Engineers
- Anyone aiming to build Kubernetes-native applications
(Certified Kubernetes Application Developer (CKAD)) Certification Overview
The Certified Kubernetes Application Developer (CKAD) program is delivered via DevOpsSchool and hosted on devopsschool.com. It is structured as a hands-on certification with a strong emphasis on practical implementation.
- Certification Levels: Entry to intermediate level Kubernetes certification focused on application deployment rather than cluster administration
- Assessment Approach: Performance-based exam where candidates solve real Kubernetes tasks in a live environment
- Ownership: Industry-aligned training backed by Kubernetes ecosystem practices
- Structure: Includes modules on pods, deployments, services, configuration, security, and troubleshooting
Skills You’ll Gain
- Kubernetes architecture and core concepts
- Deploying and managing applications using Pods and Deployments
- Working with Services, ConfigMaps, and Secrets
- Application scaling and rolling updates
- Debugging Kubernetes applications
- YAML configuration and manifest creation
- Networking and service exposure in Kubernetes
Real-World Projects You Should Be Able to Do After It
- Deploy a microservices-based application on Kubernetes
- Build CI/CD pipelines integrated with Kubernetes deployments
