Training Details
We prioritize covering all objectives and concepts necessary for passing the Certified Kubernetes Application Developer (CKAD) exam. You will command and configure a high availability Kubernetes environment (and later, build your own) capable of demonstrating all “K8s’’ features discussed and demonstrated in this course. Your week of intensive, hands-on training will conclude with a mock CKAD exam that matches the real thing.

- Deploy applications to a Kubernetes cluster
- Use Kubernetes primitives to implement common deployment strategies (e.g. blue/green or canary)
- Define, build and modify container images
- Implement probes and health checks
- Understand multi-container Pod design patterns (e.g. sidecar, init, and others)
- Understand ConfigMaps
- Create & consume Secrets
