Kubernetes Administrator CKA Course

Kubernetes Administrator CKA

The Kubernetes Administrator CKA Course covers the fundamentals of Kubernetes, a powerful container orchestration platform. You'll learn about its architecture, components, and various tools, as well as how to install, configure, and manage Kubernetes clusters. The course delves into storage and networking, exploring volumes, data, services, and ingress. You'll also study scheduling, logging, troubleshooting, and security aspects, including authentication and authorization. Throughout the course, hands-on labs offer practical experience with the concepts and technologies discussed. Upon completion, you'll be well-prepared to pursue the CKA certification, validating your expertise in managing Kubernetes environments.

Course Objectives
