CKAD Prep

This course provides a comprehensive overview of the key areas tested in the Certified Kubernetes Application Developer (CKAD) certification exam. It's designed to equip you with the knowledge and skills required to successfully manage and deploy containerized applications on Kubernetes clusters.

Course Objectives:

• Gain a solid understanding of core Kubernetes concepts, configuration options, and observability techniques.

• Design and build effective Kubernetes pods utilizing best practices for multi-container deployments, state management, and resource utilization.

• Master application deployment strategies using Kubernetes primitives, rolling updates, and Helm package management.

• Implement robust application monitoring and maintenance practices through probes, health checks, logs, and debugging techniques.

• Secure your applications within the Kubernetes environment by leveraging Custom Resource Definitions (CRDs), authentication, authorization, admission control, resource quotas, and security contexts.

• Effectively manage network access to applications using NetworkPolicies, Services, and Ingress rules.
