Terraform Module for provisioning GKE Autopilot

This Terraform module creates a Google Kubernetes Engine (GKE) Autopilot cluster in a specified project, region and network. It supports public and private clusters with optional NAT gateway and bastion host.

Variables

• project_id: The ID of the project where the cluster will be created.
• network_name: The name of the network where the cluster will be created.
• subnet_name: The name of the subnet where the cluster will be created.
• region: The region where the cluster will be created.
• name: The name of the cluster.
• description: The description of the cluster.
• is_private: Whether the cluster should be private.
• release_channel (Optional): The release channel of the cluster (Default: STABLE).
• network_tags (Optional): List of network tags to apply to the cluster nodes.
• logging_components (Optional): List of logging components to enable (Default: ["SYSTEM_COMPONENTS", "WORKLOADS"]).
• fleet_project (Optional): The project where the fleet is located.
• deletion_protection (Optional): Whether to enable deletion protection for the cluster (Default: false).
• deploy_nat (Optional): Whether to deploy a NAT gateway for the cluster.
• router_name (Optional): The name of the Cloud Router for the NAT gateway.
• bastion_zone (Optional): The zone where the bastion host will be created (Default: ${var.region}-a).
• bastion_members: List of IAM members with access to the bastion host, should be specified if is_private is true.

Example

Public Cluster:

module "public_gke_autopilot" {
  source  = "layer-3/autopilot/google"

  project_id   = "my-project"
  network_name = "my-network"
  subnet_name  = "my-subnet"
  region       = "us-central1"

  name        = "my-cluster"
  description = "My Public GKE Autopilot cluster"
  is_private  = false
  deploy_nat  = true
}

Private Cluster:

module "private_gke_autopilot" {
  source  = "layer-3/autopilot/google"

  project_id   = "my-project"
  network_name = "my-network"
  subnet_name  = "my-subnet"
  region       = "us-central1"

  name        = "my-cluster"
  description = "My Private GKE Autopilot cluster"
  is_private  = true
  deploy_nat  = true

  bastion_zone    = "us-central1-a"
  bastion_members = [
    "user:my-email@example.com"
  ]
}
