Description

This course aims to help participants prepare for Certified Kubernetes Administrator examination by the Cloud Native Computing Foundation (CNCF). Hence the outline is derived out of the CKA curriculum published by CNCF and the entire course is based on Kubernetes clusters built using Kubeadm and by using Kubernetes version 1.14

Kubernetes Essentials course and Certified Kubernetes Application Developer course are mandatory pre-requisite to take up prior to taking this course, as many of the essential topics of CKA are covered as part of Kubernetes Essentials course and CKAD course.
