KFCO — Kubernetes Fundamentals and Cluster Operations
KFCO - Kubernetes Fundamentals and Cluster Operations
Course Overview
This four-day course is the first step in learning about Containers and Kubernetes Fundamentals and Cluster Operations. Through a series of lectures and lab exercises, the fundamental concepts of containers and Kubernetes are presented and put to practice by containerizing and deploying a two-tier application into Kubernetes.
