Kubernetes Fundamentals and Cluster Operations – On Demand

Course Datasheet
- Formats: Lab, Subscription
- Length: 30 Days
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
