Azure Linux Virtual Machine Terraform Module

Deploys 1+ Virtual Machines to your provided VNet This Terraform module deploys Virtual Machines in Azure with the following characteristics:

  • All VMs use managed disks
  • VM nics attached to a single virtual network subnet of your choice (new or existing) via var.subnet_id.

Usage

resource "azurerm_resource_group" "rg" {
  name = "${var.resource_group_name}"
  location = "westus"

  tags = {
    environment = "test"
    costcenter  = "12345"
    ppm         = "N/A"
    fgid        = "1234"
    appname     = "myapp"
  }
}

data "azurerm_subnet" "subnet" {
  name                  = "${var.subnet_name}"
  virtual_network_name  = "${var.vnet_name}"
  resource_group_name   = "${var.vnet_resource_group_name}"
}

module "loadbalancer" {
  source  = "git::ssh://[email protected]/deck15/terraform-azurerm-loadbalancer"
  type    = "private"
  prefix  = "MyTerraformLB"
  resource_group_name           = "${azurerm_resource_group.rg.name}"
  subnet_id                     = "${data.azurerm_subnet.subnet.id}"
  private_ip_address_allocation = "Static"
  private_ip_address            = "10.18.160.50"

  "remote_port" {
    ssh = ["Tcp", "22"]
  }

  "lb_port" {
    https = ["443", "Tcp", "443"]
  }
}

module "linux_vm" {
  source  = "git::ssh://[email protected]/deck15/terraform-azurerm-linux-vm"

  resource_group_name = "${azurerm_resource_group.rg.name}"
  node_count          = "${var.node_count}"
  subnet_id           = "${data.azurerm_subnet.subnet.id}"
  vm_name             = "${var.vm_name}"
  backend_address_pool_id = "${module.loadbalancer.azurerm_lb_backend_address_pool_id}"

  admin_username      = "${var.admin_username}"
  ssh_key_path        = "${var.ssh_key_path}"
}

Inputs

Name Description Type Default Required
resource_group_name (Required) The name of the resource group in which the resources will be created string n/a yes
subnet_id (Required) The subnet id of the virtual network where the virtual machines will reside. string n/a yes
admin_public_key Optionally supply the admin public key. If provided, will override variable: sshKey string "" no
admin_username Specifies the name of the administrator account. string "linuxadmin" no
availability_set_name (Optional) Name of the availability set. Default is derived from vm_name string "" no
backend_address_pool_id (Optional) List of Load Balancer Backend Address Pool IDs references to which this NIC belongs string "" no
boot_diagnostics_storage_uri Blob endpoint for the storage account to hold the virtual machine's diagnostic files. This must be the root of a storage account, and not a storage container. string "" no
custom_data (Optional) Specifies custom data to supply to the machine. On linux-based systems, this can be used as a cloud-init script. On other systems, this will be copied as a file on disk. Internally, Terraform will base64 encode this value before sending it to the API. The maximum length of the binary array is 65535 bytes. string "" no
data_disk Create Virtual Machine with attached managed data disk. Default false string "false" no
delete_os_disk_on_termination (Optional) Flag to enable deletion of the OS disk VHD blob or managed disk when the VM is deleted, defaults to true. string "true" no
hostname Hostname to use for the virtual machine. Uses vmName if not provided. string "" no
location (Optional) The location/region where the virtual machines will be created. Uses the location of the resource group by default. string "" no
managed_disk_create_option (Optional) The method to use when creating the managed disk. Values are Import, Empty, Copy, and FromImage. Default = Empty. string "Empty" no
managed_disk_prefix Specifies the name of the managed disk. Changing this forces a new resource to be created. string "md" no
managed_disk_size_gb (Optional) Specifies the size of the os disk in gigabytes. Default 100 GB string "100" no
managed_disk_storage_account_type (Optional) The type of storage to use for the managed disk. Allowable values are Standard_LRS or Premium_LRS. Default = Standard_LRS. string "Standard_LRS" no
managed_disk_type Specifies the type of managed disk to create. Value you must be either Standard_LRS or Premium_LRS. Cannot be used when vhd_uri is specified. string "Standard_LRS" no
node_count The number of Nodes to create string "1" no
os_disk_prefix Optional os disk name prefix to use for managed disk attached to the virtual machine string "" no
os_disk_size_gb (Optional) Specifies the size of the os disk in gigabytes. Default 32 GB string "32" no
ssh_key_path Path to the public key to be used for ssh access to the VM. Default is ~/.ssh/id_rsa.pub. If specifying a path to a certification on a Windows machine to provision a linux vm use the / in the path versus backslash. e.g. c:/home/id_rsa.pub string "~/.ssh/id_rsa.pub" no
tags (Optional) A map of the tags to use on the resources that are deployed with this module. Tags will be merged with those defined by the resource group. map { "source": "Terraform" } no
use_loadbalancer When set to true, the Virtual Network Interfaces will be assigned to the backend_address_pool_id. Default = true string "true" no
vm_name Name of the virtual machine. string "linuxcomputevm" no
vm_nic_name (Optional) Name of the Network interface for the VM string "" no
vm_os_id The resource ID of the image that you want to deploy if you are using a custom image. string "" no
vm_os_offer (Required, when not using image resource) Specifies the offer of the image used to create the virtual machine. Changing this forces a new resource to be created. string "UbuntuServer" no
vm_os_publisher (Required, when not using image resource) Specifies the publisher of the image used to create the virtual machine. Changing this forces a new resource to be created. string "Canonical" no
vm_os_sku (Required, when not using image resource) Specifies the SKU of the image used to create the virtual machine. Changing this forces a new resource to be created. string "16.04-LTS" no
vm_os_version (Optional) Specifies the version of the image used to create the virtual machine. Changing this forces a new resource to be created. string "latest" no
vm_size Azure VM Size to use. See: https://docs.microsoft.com/en-us/azure/cloud-services/cloud-services-sizes-specs string "Standard_B2s" no

Outputs

Name Description
admin_username
availability_set_id id of the availability set where the vms are provisioned.
availability_set_name Name of the availability set where the vms are provisioned.
node_names
node_private_ips private ip addresses of the vm nics
vm_ids Virtual machine ids created.

Notes

The backend_address_pool_id requires the load balancer to be created before the linux_vm can be created.
