Access private containers on Amazon ECS using PrivateLink and Terraform
To set up the infrastructure I'm using Terraform. The code is available on my GitHub. We need to create two VPCs. I've created a basic module which will create a VPC which contains four subnets (in two AZs) and deploy a NAT Gateway and an Internet Gateway. Also the route tables are configured properly.

How are most EKS clusters deployed?
If you want somewhat viable setup - I'd go for terraform-aws-modules (Anton did an awesome job), and aws-ia blueprints, especially those multi-tenant ones.
