KBS-104

Kubernetes Administration and Helm
with CKA & CKAD exam prep

Detailed Course Outline

Course Length

4 days (3 days Kubernetes + 1 day Helm)

Course Overview

Kubernetes is the leading open-source system for automating deployment, scaling and management of containerized applications. This course introduces participants to the basic concepts and architecture of Kubernetes, its initial install, setup and access control, Kubernetes Pods and Workloads, Scheduling and node management, Accessing the applications, Persistent storage in Kubernetes and its Logging, Monitoring and Troubleshooting facilities.

The second part deals with Helm, the Kubernetes Package Manager. This course not only covers the daily administration of Kubernetes-based systems but also prepares delegates for the official Certified Kubernetes Administrator (CKA) and Certified Kubernetes Application Developer (CKAD) exams of the Cloud Native Computing Foundation (CNCF).

Learning Objectives

Upon completion of this course, participants will be able to:

  • • Understand Kubernetes architecture and core concepts
  • • Install and configure a Kubernetes cluster
  • • Manage Kubernetes workloads: Pods, Deployments, Jobs, DaemonSets
  • • Configure RBAC and access control
  • • Manage scheduling, node affinity, taints and tolerations
  • • Configure Services, Ingress and Network Policies
  • • Work with persistent storage, Secrets and ConfigMaps
  • • Monitor, log and troubleshoot Kubernetes clusters
  • • Install and use Helm, the Kubernetes Package Manager
  • • Work with Helm charts, templates, repositories and plugins
  • • Prepare for the CKA and CKAD certification exams

Prerequisites

Proficiency with the Linux CLI. A broad understanding of Linux system administration. Basic knowledge of Linux containers, e.g. Docker.

Structure

50% theory, 50% hands-on lab exercises

Target Audience

System administrators, developers and DevOps engineers who want to understand and use Kubernetes in cloud and data center environments.
