Cloud Native Computing Foundation (CNCF) Certified Kubernetes Administrator (CKA)

The accelerated Certified Kubernetes Administrator (CKA) certification is a program that allows users to demonstrate their competence in a hands-on, command-line environment.

The purpose of the Certified Kubernetes Administrator (CKA) program is to provide assurance that CKAs have the skills, knowledge, and competency to perform the responsibilities of Kubernetes administrators.

Upon completion of the course the certified K8s administrator will have demonstrated the ability to do basic installation as well as configuring and managing production-grade Kubernetes clusters. They will have an understanding of key concepts such as Kubernetes networking, storage, security, maintenance, logging and monitoring, application lifecycle, troubleshooting, API object primitives and the ability to establish basic use-cases for end users.

At the end of this course, you’ll achieve your Certified Kubernetes Administrator (CKA) certification. Through Firebrand’s Lecture | Lab | Review methodology, you’ll get certified at twice the speed of the traditional training and get access to courseware, learn from certified instructors, and train in a distraction-free environment.
