ALT3-CKAD

Certified Kubernetes Application Developer – CKAD

Description

This class prepares students for the Certified Kubernetes Application Developer (CKAD) exam. Kubernetes is a Cloud Orchestration Platform providing reliability, replication, and stability while maximizing resource utilization for applications and services. By the conclusion of this hands-on training, you will go back to work with all necessary commands and practical skills to empower your team to succeed, as well as gain knowledge of important concepts like Kubernetes architecture and container orchestration.  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.

This is a Lab Intensive, hands-on course.

All topics required by the CKAD exam, including:

  • 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
  • Troubleshooting and debugging tools
  • Provide and troubleshoot access to applications via services
  • Use Ingress rules to expose applications
