Terraform EKS + GHCR

Terraform IaC Solution to Provision an AWS EKS Cluster with GitHub Container Registry.

This setup would serve to establish a container orchestration platform.

A cluster-specific VPC ensures isolation from other resources of the cloud network.

A provisioned ELB and AWS Load Balancer Controller allows load-balanced network connectivity. To create an ALB and the necessary supporting resources, an Ingress config should be annotated with:

annotations:
    kubernetes.io/ingress.class: alb

Requirements

• terraform
• awscli (configured to use a valid AWS account)
• eksctl
• kubectl
• wget
• jq This config was setup on a Mac, if it is to be used on a linux computer, the sed command in ./external/setup.sh must be corrected appropriately.

Setup

To provision an AWS EKS cluster:

# Initialize terraform
terraform init
# Provision Infrastructure
terraform apply -var "gh_user=githubUsername" -var "gh_pat=githubPersonalAccessToken"

The properties of provisioned cluster can be tweaked by adjusting ./variables.tf accordingly. The variables has explanatory descriptions.
