terraform-aws-eks-blueprints VS terraform-aws-vpc

Have you checked out this repo https://github.com/aws-ia/terraform-aws-eks-blueprints

Now that you have the networking part done, you can build configurations for the EKS cluster and its add-ons. You will use the terraform-aws-modules to create the EKS cluster and eks_blueprints module from terraform-aws-eks-blueprintsto configure EKS add-ons.

[other configuration] taints = { dedicated = { key = "nvidia.com/gpu" value = "true" effect = "NO_SCHEDULE" } } # ... [other configuration] } } }

Anyone using eks blueprints or cloudposse's module?

Take a look at the EKS Blueprints for Terraform as a place to start. I know the team is working on their v5 release which should be a solid improvement. https://github.com/aws-ia/terraform-aws-eks-blueprints/milestone/1

Take a look at the EKS Blueprints for Terraform v5 rewrite for more details. However, EKS Blueprints for Terraform (v4 as it is today) is pretty darn good _if_ you just want to manage basic charst like load balancer controller and Karpenter. It provisions IAM Roles and Policies along with Helm charts all in one easy set-up. It's just not something I'd want to touch with more complex use cases and we'll see how the EKS Blueprints team does with the v5 rewrite - their direction looks reasonable, but Terraform just isn't really designed for the problem it's trying to solve there, so it's going to be somewhat clunky one way or another.

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.
