  availability_zones      = ["eu-west-1a", "eu-west-1b", "eu-west-1c"]
  cluster_name            = "my-cluster"
  node_instance_types     = ["c5.large"]
  node_group_desired_size = 2
  node_group_max_size     = 6
  node_group_min_size     = 2
  tags = {
    Environment = "production"
    Team        = "Platform Engineering"
  }
}

Inputs

• name: Name of the EKS cluster.
• region: AWS region.
• vpc_cidr_block: CIDR block for the VPC.
• public_subnet_cidrs: List of CIDR blocks for public subnets.
• private_subnet_cidrs: List of CIDR blocks for private subnets.
• availability_zones: List of availability zones for the subnets.
• cluster_name: Name of the EKS cluster.
• node_instance_types: List of instance types for the worker nodes.
• node_group_desired_size: Desired size of the node group.
• node_group_max_size: Maximum size of the node group.
• node_group_min_size: Minimum size of the node group.
• tags: Tags to apply to the resources.

Outputs

• eks_cluster_id: ID of the EKS cluster.
• eks_cluster_endpoint: Endpoint of the EKS cluster.
• eks_cluster_certificate_authority: Certificate authority data for the cluster.
• eks_cluster_oidc_issuer_url: OIDC issuer URL of the EKS cluster.
• eks_node_group_role_arn: ARN of the node group IAM role.
• eks_autoscaler_role_arn: ARN of the cluster autoscaler IAM role.
• eks_cluster_oidc_provider_arn: ARN of the OIDC provider for the EKS cluster.
• eks_cluster_oidc_provider_id: ID of the OIDC provider for the EKS cluster.

Notes

• The module creates a VPC, subnets, and other necessary resources in the specified region.
• The module creates a node group with the specified instance types and autoscaling configuration.
• The module creates an IAM role for the node group and a cluster autoscaler role.
• The module creates an OIDC provider for the EKS cluster.
• The module creates an IAM policy for the EKS cluster autoscaler.
• The module creates an IAM role for the EKS cluster autoscaler.
• The module creates an IAM policy for the EKS cluster autoscaler.

Terraform State

The Terraform state is stored in an S3 bucket and a DynamoDB table. The bucket and table are created in the root module.

Terraform State Locking

The Terraform state is locked using a DynamoDB table. The table is created in the root module.
