Kubernetes Virtual Machines Module

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

Usage

  source                             = "walmartdigital/vms-k8s/azurerm"
  version                            = "1.0.0"

  bastion_ssh_allowed_ips            = []
  cluster_name                       = ""
  default_tags                       = {

  lb_ports                           = [{
    name            = "http"
    port            = "80"
    protocol        = "Tcp"
    backend_port    = 30000
    probe_port      = 30000
    probe_path      = "/"
    probe_interval  = 15
    probe_threshold = 3
    target          = "workers"
    visibility      = "public"
  }, {
    name            = "http"
    port            = "80"
    protocol        = "Tcp"
    backend_port    = 30000
    probe_port      = 30000
    probe_path      = "/"
    probe_interval  = 15
    probe_threshold = 3
    target          = "workers"

  ssh_public_key                     = "abc123"
  subnet_name                        = "my-subnet-name"
  vnet_name                          = "my-vnet-name"
  bastion_image_name                 = "bastion-v1.0.0"
  worker_count                       = 3
  worker_vm_size                     = "Standard_DS4_v2"
}

By default all ssh access to to Bastion is blocked. If its needed allow access trough internet, must be used a white list of allowed ips:

bastion_ssh_allowed_ips                 = ["10.0.0.1", "AzureCloud"]

Take on consideration that can be used Azure wildcards like AzureCloud (allow access to any azure public cloud).

Outputs

• bastion_public_ip: The bastion public IP address.
• bastion_private_ip: The bastion private IP address.
• worker_ips: The private IPs of the created worker VMs.
• manager_ips: The private IPs of the created manager VMs.
