VMware Kubernetes Fundamentals and Cluster Operations-On Demand (EDU-KFCO-EL)

This course, equivalent to 4 days of training, 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.


Objectives

By the end of the course, you should be able to meet the following 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

 

Intended Audience

  • Anyone who is preparing to build and run Kubernetes clusters
