The following lines are explanation of a project I have been working on and still being developed by adding new infrastructure and features.

THE PROJECT

As the title says this projects is about deploying an AWS EKS cluster, cluster addons, VPC and IAM roles using IaC with Terraform.

AWS EKS

• Creates an EKS cluster with specified Kubernetes version.
• Configures authentication and access control using IAM roles.
• Adds EKS-managed add-ons like CoreDNS, VPC CNI, and AWS EBS CSI Driver
• Manages node groups (on-demand and spot instances) for cost optimization.

AWS VPC

• Creates a VPC with a specified CIDR block.
• Defines public and private subnets for workload segregation.
• Supports NAT Gateway for private subnets to access the internet securely.
• Enables DNS internal service discovery.

AWS IAM Roles & Policies

• EKS Admin Role: Grants cluster admin access.
• Load Balancer Role: Manages AWS Load Balancer Controller.
• VPC CNI IRSA Role: Allows the VPC CNI plugin to operate securely.
• EBS CSI IRSA Role: Enables EBS CSI driver for persistent storage.

Terraform

• AWS Provider: Manages EKS, VPC, IAM and etc.
• Kubernetes Provider: Configures Kubernetes objects in the cluster.
• Helm Provider: Deploys Helm charts for add-ons like AWS Load Balancer Controller.
