Description

The AWS Load Balancer Controller is used to help manage and control the provisioning of ALBs (Ingress resources) and NLBs (Service resources - type LoadBalancer).

In this lab scenario, you'll learn how to deploy the AWS Load Balancer Controller into a lab-provided EKS cluster using Helm. You'll then deploy a sample TCP Echo App and configure external public access to it via a Service (type LoadBalancer) cluster resource.

Learning Objectives

Upon completion of this lab, you will be able to:

  • Deploy and configure the AWS Load Balancer Controller into an EKS cluster
  • Deploy a TCP Echo App and expose it publicly using a Service (type LoadBalancer) resource

Intended Audience

This lab is intended for:

  • Kubernetes practitioners
  • DevOps Engineers
  • SREs

Lab Prerequisites

You should be familiar with:

  • Basic Linux command line administration
  • Basic Kubernetes and Container-based concepts

Consider taking the following courseware in preparation for this lab:

Lab Environment

This Lab will start with the following AWS resources provisioned automatically for you:

  • 1 x EKS cluster - Cluster-1 - provides a fully functional Kubernetes cluster 
    • 1 x NodeGroup
      • 1 x EC2 Worker Node
  • 2 x EC2 instances
    • eks.launch.instance - used to launch the EKS cluster
    • cloudacademylabs - used to provide an SSH based terminal

Updates

December 5th, 2023 - Updated Kubernetes version

June 22nd, 2023 - Resolved intermittent deployment issue

June 5th, 2023 - Resolved an issue that caused the lab to fail to setup on rare occasions
