Certified Kubernetes Administrator (CKA): Unit 1

About this course

This course teaches you the core skills for building, managing, and securing Kubernetes clusters. You’ll start by learning how Kubernetes works and how its components fit together. Using kubeadm, you’ll set up clusters, handle everyday management tasks, and maintain nodes for reliable performance. Through hands-on labs, you’ll practice real-world tasks like managing containers with CricTL and backing up or restoring etcd. You’ll also learn how to secure clusters by configuring API access, setting security contexts, and using RBAC for users and service accounts. By the end, you’ll have the practical knowledge to deploy and maintain secure, highly available Kubernetes clusters.

What you will learn

• Understand Kubernetes architecture, node roles, and ecosystem integration for both cloud and on-premises deployments.
• Build and configure Kubernetes clusters using kubeadm, including networking and client setup.
• Perform essential cluster management and node maintenance tasks, including monitoring, upgrades, and high availability.
• Implement robust security settings, including API access controls, security contexts, and RBAC for users and service accounts.
