Terraform module which creates AWS EKS (Kubernetes) resources with an opinionated configuration targeting Camunda 8.
Following is a simple example configuration and should be adjusted as required.
See inputs for further configuration options and how they affect the cluster creation.
module "eks_cluster" {
source = "github.com/camunda/camunda-tf-eks-module/modules/eks-cluster"
region = "eu-central-1"
name = "cluster-name"
cluster_service_ipv4_cidr = "10.190.0.0/16"
cluster_node_ipv4_cidr = "10.192.0.0/16"
}
