terraform-aws-eks-blueprints VS terraform-cdk

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.

## (https://github.com/aws-ia/terraform-aws-eks-blueprints) ## ... [other Terraform code] ## Cluster Configuration module "eks" { # ... [other configuration] self_managed_node_groups = { gpu_node_group = { node_group_name = "gpu-node-group" ami_type = "AL2_x86_64_GPU" capacity_type = "ON_DEMAND" instance_types = [ "g4dn.xlarge", "g4dn.2xlarge", ] # ... [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.

At first I tested it to deploy an OVHcloud Managed Kubernetes Service (MKS) with a Node Pool. And step by step, it worked. I even created a Pull Request (PR) in the terraform-cdk repository to add it as an example ☺️.

I'll be trying more sample app deployments with CDK and maybe even explore CDK for Terraform.

You can use CDK with other providers using https://github.com/hashicorp/terraform-cdk

In my experience, CDK is far better than Pulumi, especially if you're mostly going to be using AWS.

I, personally, prefer Crossplane Composite Functions on top of CDK8S, but had dropped CDKTF due to bloat. You can actually manage Kubernetes updates/upgrade lifecycle with Crossplane, as well.

I was going to recommend Pulumi, but looks like CDK for Terraform is still being kept up to date.

Avoid Pulumi, get directly to source and use https://github.com/hashicorp/terraform-cdk
