Kubernetes Virtual Machines Module

This module create all required resources for deploy a Virtual Machines to host a kubernetes cluster using RKE (Rancher Kubernetes Engine).

Usage

module "az_vms" {

  name_suffix               = "abc123"
  cluster_name              = "my-cluster"
  environment               = "staging"
  main_resource_group       = "my-resource-group"
  vnet_name                 = "my-vnet-name"
  subnet_name               = "my-subnet-name"
  images_resource_group     = "my-images-resource-group"
  k8s_image_name            = "k8s-v1.0.0"
  bastion_image_name        = "bastion-v1.0.0"
  ssh_public_key            = "abc123"
  worker_count              = "2"
  network_security_group_id = "network-security-group-id"
  lb_address_pool_id        = "loadbalancer-address-pool-id"
  worker_vm_size            = "my-worker-vm-size"
  manager_vm_size           = "my-manager-vm-size"
}

You can use our k8s-lb-module and k8s-nsg-module to configure and use a Load Balancer and Network Security Group 100% compatible with this module
