Provisioning the Amazon EKS cluster using Terraform

This repository contains the terraform file code, which we can use to provision the Amazon EKS cluster as part of Project 4 of our 10WeeksofCloudOps series! In this comprehensive hands-on project, we dive deep into the world of GitOps and ArgoCD, demonstrating how to implement these essential DevOps practices step by step by dockerizing the application and provisioning the infrastructure using Terraform(this repo).

Architecture Diagram

Installation of Terraform

Follow the below steps to Install the Terraform and another dependency.

1️⃣ Clone the repo

git clone https://github.com/piyushsachdeva/10weeksofcloudops-week4-tf.git

2️⃣ Let's install dependency to deploy the application

cd kube_terraform/ToDo-App/
terraform init

3️⃣ Edit the below file according to your configuration

vim kube_terraform/ToDo-App/backend.tf

add below code

terraform {
  backend "s3" {
    bucket = "S3-BUCKET-NAME"
    key    = "backend/TFSTATE-FILE.tfstate"
    region = "us-east-1"
    dynamodb_table = "DYNAMODB-TABLE-NAME"
  }
}

Let's set up the variable for our Infrastructure and create one file with the name of terraform.tfvars inside kube_terraform/ToDo-App/backend.tf and add the below conntent into that file.

REGION          = "us-east-1"
PROJECT_NAME    = "ToDo-App"
VPC_CIDR        = "10.0.0.0/16"
PUB_SUB1_CIDR   = "10.0.1.0/24"
PUB_SUB2_CIDR   = "10.0.2.0/24"
PRI_SUB3_CIDR   = "10.0.3.0/24"
PRI_SUB4_CIDR   = "10.0.4.0/24"

Please note that the above file is crucial for setting up the infrastructure, so pay close attention to the values you enter for each variable.

It's time to build the infrastructure

The below command will tell you what terraform is going to create.

terraform plan

Finally, HIT the below command to create the infrastructure...

terraform apply

type yes, and it will prompt you for permission or use --auto-approve in the command above.
