terraform-aws-eks-clickhouse

Terraform module for creating EKS clusters optimized for ClickHouse with EBS and autoscaling.

Usage

provider "aws" {
  # https://registry.terraform.io/providers/hashicorp/aws/latest/docs
}

module "eks_clickhouse" {
  source  = "github.com/Altinity/terraform-aws-eks-clickhouse"

  cluster_name = "clickhouse-cluster"
  region       = "us-east-1"
  cidr         = "10.0.0.0/16"
  subnets      = [
    { cidr_block = "10.0.1.0/24", az = "us-east-1a" },
    { cidr_block = "10.0.2.0/24", az = "us-east-1b" },
    { cidr_block = "10.0.3.0/24", az = "us-east-1c" }
  ]

  node_pools_config = {
    scaling_config = {
      desired_size = 2
      max_size     = 10
      min_size     = 0
    }

    disk_size      = 20
    instance_types = ["m5.large"]
  }

  tags = {
    CreatedBy = "mr-robot"
  }
}

This module will create a Node Pool for each combination of instance type and subnet. For example, if you have 3 subnets and 2 instance types, this module will create 6 different Node Pools.
