Course Overview

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 into practice by containerizing and deploying a two-tier application into Kubernetes.

Objectives
By the end of the course, students should be able to meet the following objectives:
test, and publish Docker container images
familiar with YAML files that define Kubernetes objects
Kubernetes core user-facing concepts, including pods, services, and deployments
kubectl, the Kubernetes CLI, and become familiar with its commands and options
the architecture of Kubernetes (the control plane and its components, worker nodes, and kubelet)
how to troubleshoot issues with deployments on Kubernetes
resource requests, limits, and probes to deployments
dynamic application configuration using ConfigMaps and Secrets
other workloads, including DaemonSets, Jobs, and CronJobs
about user-facing security using SecurityContext, RBAC, and NetworkPolicies
Audience
Anyone who is preparing to build and run Kubernetes clusters.
