Setting Up Istio on AWS EKS with Terraform and the Istio Operator

If you're stepping into the realm of Kubernetes on AWS EKS (Elastic Kubernetes Service), the journey can be daunting, especially when it comes to service mesh configurations like Istio. Installing Istio may seem complicated, but with the right approach and tools, you can simplify this process significantly. In this guide, we will dive into how to effectively install Istio on AWS EKS using Terraform and the Istio Operator.

Why Istio?

Before we jump into the installation process, let's briefly address why Istio is essential to your Kubernetes operations. Istio:

Manages Traffic: This allows you to easily control the flow of traffic and API calls between services.

Secures Connections: Istio has spring-loaded security features that enable you to create secure connections between your services.

Observability: With built-in telemetry, Istio gives you deeper insight into your system's performance.

Prerequisites

To follow along with this guide, make sure you have the following:

An AWS account with EKS set up

Basic understanding of Kubernetes

Terraform installed on your local machine

kubectl configured to interact with your EKS cluster

Step-by-Step Installation Guide

Now, let’s break down the process of installing Istio on EKS using Terraform and the Istio Operator into manageable steps.

Step 1: Download Istio Control Plane

Start by downloading the Istio command-line tool. This can be done with the following command in your terminal:

Step 3: Create Istio Components Using YAML Files

You’ll need to create two YAML files: one for the Istio Operator and another for its customization. This will drive the installation of the Istio components.

istio-operator.yaml file should look like this:

Step 4: Define Terraform Configuration

The final step involves integrating Terraform into your installation process. Create a Terraform file called main.tf and add the following to execute the Istio installation:

Step 5: Create Modules

To make the management of your Terraform resources simpler, create modules for the IstioOperator and Istio installation resources. Organize your Terraform scripts into the following structure:

Conclusion

By following this guide, you should now have Istio installed on your AWS EKS cluster with Terraform and the Istio Operator. With Istio set up, you can start exploring the extensive features of service mesh management. Remember, practice is key, and as you venture deeper into Kubernetes and Istio, it will become more natural to navigate through these technologies.

Whether you’re experimenting or producing production-level applications, having Istio in your toolkit can enhance the capabilities of your Kubernetes environment significantly.
