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.

Upon completing this course, the learner will be able to meet these overall objectives: Build, test, and publish Docker container images Become familiar with YAML files that define Kubernetes objects Understand Kubernetes core user-facing concepts, including pods, services, and deployments Use kubectl, the Kubernetes CLI, and become familiar with its commands and options Understand the architecture of Kubernetes (Control plane and its components, worker nodes, and kubelet) Learn how to troubleshoot issues with deployments on Kubernetes Apply resource requests, limits, and probes to deployments Manage dynamic application configuration using ConfigMaps and Secrets Deploy other workloads, including DaemonSets, Jobs, and CronJobs Learn about user-facing security using SecurityContext, RBAC, and NetworkPolicies

The primary audience for this course is anyone who is preparing to build and run Kubernetes clusters.
