Certified Kubernetes Application Developer (CKAD)

The Certified Kubernetes Application Developer (CKAD) certification, offered by the Linux Foundation and the Cloud Native Computing Foundation (CNCF), is a globally recognized, performance-based credential that validates expertise in designing, building, configuring, and deploying cloud-native applications on Kubernetes. This course prepares candidates for the CKAD exam, focusing on defining application resources, leveraging Kubernetes primitives, and managing scalable microservice applications written in languages like Java, Go, Python, Node.js, or others. Ideal for developers working with containerized environments, the CKAD certification demonstrates proficiency in creating robust applications ready for production Kubernetes clusters.

This course is ideal for:

• Developers building and deploying cloud-native applications.
• DevOps engineers seeking expertise in Kubernetes application management.
• Professionals preparing for the Certified Kubernetes Application Developer (CKAD) exam.
• Software engineers familiar with microservices and container runtimes.

Prerequisites

To succeed in this course, participants should have:

• Basic familiarity with container runtimes (e.g., Docker) and microservice architectures.
• Experience with a programming language (e.g., Java, Go, Python, Node.js).
• Access to a Kubernetes environment (e.g., Minikube, kind, or a cloud-based cluster) for practice.

What You Will Learn

In this course, you will gain expertise in:

• Defining and configuring Kubernetes API primitives and Pods.
• Managing application configurations with ConfigMaps, Secrets, and ServiceAccounts.
• Implementing observability with probes, logging, and debugging techniques.
• Deploying scalable applications with networking, storage, and state persistence.

Benefits of the Course
