You need a microservice stack to deploy to the cluster. I'm using a microservice stack scaffolded for demo purposes using JHipster. You can use another microservice stack if you want. If you prefer using the same application as in this demo, then you can either scaffold it using JHipster JDL or clone the sample repository from GitHub.

ECR VPC ECS

Now let us move on to the important part of the tutorial. Creating an EKS cluster in AWS is not as straightforward as in other cloud platforms. You need to also create a lot more resources for everything to work correctly without surprises. You will be using a bunch of Terraform providers to help with this, and you will also use some prebuilt Terraform modules like AWS VPC Terraform module and Amazon EKS Blueprints for Terraform to reduce the amount of boilerplate you need to write.

The infrastructure is created using terraform, and can be found in this git repository. The project uses community maintained AWS Terraform modules, which simplify this process. The code examples that follow in the post are using the vpc-endpoints module to create the Gateway and interface endpoints.

Let us use an example from AWS to see how we can use a publicly available module. When setting up a virtual network (or Virtual Private Cloud, VPC) in AWS there are a lot of resources you must create. One popular module is the AWS VPC module. The documentation for this module is available at registry.terraform.io/modules/terraform-aws-modules/vpc/aws. The simplest example of using this module looks like this:

locals { region = data.aws_region.current.name } module "vpc" { source = "git::https://github.com/terraform-aws-modules/terraform-aws-vpc.git?ref=v3.16.0" name = var.vpc_name cidr = var.vpc_cidr azs = ["${local.region}a", "${local.region}b"] public_subnets = cidrsubnets(var.vpc_cidr, 1, 1) enable_dns_hostnames = true enable_dns_support = true map_public_ip_on_launch = true tags = { Name = var.vpc_name } public_subnet_tags = { Name = "public subnet" "kubernetes.io/role/elb" = "1" "kubernetes.io/cluster/${var.cluster_name}" = "shared" } }

/u/akirakotkata all of the answers in this thread are correct, but nobody's empowered you to figure this out on your own in the future. In the registry link you provided, there's a link to Source Code. Follow that link and take a look at variables.tf in the repo, lines 13-17. That block is what is expected for the parameter, so you need to tweak what you're sending into what it expects.
