Creating an EKS cluster

Yesterday I was helping a colleague create an AWS EKS cluster using the official terraform module released by AWS. If you look through it, you’ll see it’s pretty complicated. It expects 62 different input configs and even the examples look daunting to the point I can’t copy and paste them here, they’re that long! See for yourself:

terraform-aws-eks/main.tf at master · terraform-aws-modules/terraform-aws-eks
You can't perform that action at this time. You signed in with another tab or window. You signed out in another tab or…

Today I also needed to create another AWS EKS cluster for a customer that agreed to use SUSE Rancher. This is the whole code for it:

resource "rancher2_cluster" "cluster" {
  name = "rancher-demo"
  description = "Terraform EKS cluster from Rancher"
  eks_config_v2 {
    cloud_credential_id = data.rancher2_cloud_credential.aws.id
    region = "us-east-1"
    kubernetes_version = "1.21"
    logging_types = ["audit", "api"]
    node_groups {
      name = "rancher-main"
      instance_type = "m5.large"
      desired_size = 3
      max_size = 5
      request_spot_instances = true
    }
    private_access = true
    public_access = true
  }
}

As you can see, SUSE Rancher is far more than a Web UI for Kubernetes. It has lots of great features but don’t forget the underlying API is for you to use and this is a good example of how it can improve security and productivity at your company.
