For a list of all variables, see the README.md or the variables.tf file.

Required providers

Starting in Materialize on AWS Terraform module v0.3.0, you need to declare the following providers:

provider "aws" {
  region = "us-east-1"  # or some other region
  # Specify additional AWS provider configuration as needed
}

# Required for EKS authentication
provider "kubernetes" {
  host                   = module.eks.cluster_endpoint
  cluster_ca_certificate = base64decode(module.eks.cluster_certificate_authority_data)

  exec {
    api_version = "client.authentication.k8s.io/v1beta1"
    args        = ["eks", "get-token", "--cluster-name", module.eks.cluster_name]
    command     = "aws"
  }
}

# Required for Materialize Operator installation
provider "helm" {
  kubernetes {
    host                   = module.eks.cluster_endpoint
    cluster_ca_certificate = base64decode(module.eks.cluster_certificate_authority_data)

    exec {
      api_version = "client.authentication.k8s.io/v1beta1"
      args        = ["eks", "get-token", "--cluster-name", module.eks.cluster_name]
      command     = "aws"
    }
  }
}

Swap support

Starting in v0.6.1 of Materialize on AWS Terraform, disk support (using swap on NVMe instance storage) may be enabled for Materialize. With this change, the Terraform:

Creates a node group for Materialize.
Configures NVMe instance store volumes as swap using a daemonset.
Enables swap at the Kubelet.

For swap support, the following configuration option is available:

swap_enabled
