How To Deploy an Amazon EKS Cluster with Terraform Remote State, NodePort, and Load Balancers

In this video, I’m going to walk you through a comprehensive step-by-step tutorial on how to deploy an Amazon EKS Cluster using Terraform, complete with remote state storage in AWS S3 and DynamoDB for state locking, as well as setting up Kubernetes NodePort and Load Balancers.
If you're a DevOps engineer, cloud architect, or even a beginner looking to gain hands-on experience with Terraform and Kubernetes, this tutorial is for you. By the end of this video, you will have a solid understanding of how to use Terraform to automate your infrastructure on AWS, manage remote state for collaboration, deploy Kubernetes resources on Amazon EKS, and configure a NodePort Service and Load Balancers to expose your application to the public.
What You’ll Learn in This Video:
01. How to Set Up Terraform Backend: I’ll explain how I configured AWS S3 to store Terraform state files and DynamoDB to lock the state, ensuring multiple users or systems don't accidentally corrupt the state during concurrent runs.
02. VPC and Networking Setup: I’ll walk you through creating a Virtual Private Cloud (VPC), subnets, and routing tables, which will serve as the foundation for your Amazon EKS cluster and the resources needed to support it.
03. Deploying Amazon EKS with Terraform: I’ll show you how to provision an Elastic Kubernetes Service (EKS) cluster on AWS using Terraform, including the IAM roles and policies required to give Kubernetes the necessary permissions on AWS.
04. Provisioning EC2 Bastion Host: I’ll explain how I set up a bastion host, which you can use for secure access to your Kubernetes nodes for troubleshooting and management.
05. Creating Kubernetes Node Groups: Learn how to define node groups for both public and private EC2 instances that will act as the worker nodes for your Kubernetes cluster.
06. Deploying Kubernetes Resources: I’ll walk you through deploying a Kubernetes Deployment and exposing it using both a NodePort Service and Load Balancers to make your application accessible from the outside.
07. Configuring and Using NodePort: I’ll show you how to configure a NodePort Service that exposes your Kubernetes application on specific ports, allowing you to access it from the public network.
08. Setting Up Load Balancers: I’ll explain how I configured both a Classic Load Balancer (CLB) and a Network Load Balancer (NLB) to handle incoming traffic to your application and distribute it across the Kubernetes nodes.
09. Verifying Resources in AWS Console: I’ll demonstrate how to verify that your EKS cluster, EC2 instances, and Load Balancers have been successfully deployed by checking them in the AWS Management Console.
10. Accessing Your Application: After deploying everything, I’ll show you how to access the sample application using the NodePort service. I’ll also explain the importance of properly managing security groups to open and close ports as necessary.
11. Clean-Up: Finally, I’ll walk you through how to safely clean up all the resources we deployed in this tutorial to avoid any unnecessary costs.
Why This Tutorial is Important:
Deploying and managing infrastructure manually can lead to inconsistencies and increased downtime. By using Terraform to deploy an Amazon EKS cluster, I’ll show you how to automate this process and ensure consistency in your infrastructure. This also includes using AWS S3 and DynamoDB to handle remote state management and prevent the common problem of multiple users accidentally modifying the state at the same time.
In addition, with Kubernetes becoming the go-to solution for container orchestration, knowing how to integrate NodePort and Load Balancers into your Kubernetes setup will give you the edge in managing traffic to your cloud-native applications.
Technologies Used:
Terraform: I’ll use it to automate the provisioning of AWS resources like EKS clusters, VPCs, EC2 instances, and Kubernetes services.
Amazon EKS: For deploying and managing Kubernetes workloads on AWS.
AWS S3 & DynamoDB: For storing Terraform’s remote state and locking mechanisms.
Kubernetes: To manage containerized applications, including setting up deployments, NodePort, and Load Balancers.
Amazon EC2: For provisioning the worker nodes for the EKS cluster.
AWS Network Load Balancer (NLB) & Classic Load Balancer (CLB): To handle external traffic coming into your Kubernetes applications.
