azurerm_virtual_network

Manages a virtual network including any configured subnets. Each subnet can optionally be configured with a security group to be associated with the subnet.

NOTE on Virtual Networks and Subnet's: Terraform currently provides both a standalone Subnet resource, and allows for Subnets to be defined in-line within the Virtual Network resource. At this time you cannot use a Virtual Network with in-line Subnets in conjunction with any Subnet resources. Doing so will cause a conflict of Subnet configurations and will overwrite Subnet's.

Example Usage

resource "azurerm_resource_group" "test" {
  name     = "acceptanceTestResourceGroup1"
  location = "West US"
}

resource "azurerm_network_security_group" "test" {
  name                = "acceptanceTestSecurityGroup1"
  location            = "${azurerm_resource_group.test.location}"
  resource_group_name = "${azurerm_resource_group.test.name}"
}

resource "azurerm_virtual_network" "test" {
  name                = "virtualNetwork1"
  resource_group_name = "${azurerm_resource_group.test.name}"
  address_space       = ["10.0.0.0/16"]
  location            = "West US"
  dns_servers         = ["10.0.0.4", "10.0.0.5"]

  subnet {
    name           = "subnet1"
    address_prefix = "10.0.1.0/24"
  }

  subnet {
    name           = "subnet2"
    address_prefix = "10.0.2.0/24"
  }

  subnet {
    name           = "subnet3"
    address_prefix = "10.0.3.0/24"
    security_group = "${azurerm_network_security_group.test.id}"
  }

  tags {
    environment = "Production"
  }
}

Argument Reference

The following arguments are supported:

• name - (Required) The name of the virtual network. Changing this forces a new resource to be created.

• resource_group_name - (Required) The name of the resource group in which to create the virtual network.

• address_space - (Required) The address space that is used the virtual network. You can supply more than one address space. Changing this forces a new resource to be created.

• location - (Required) The location/region where the virtual network is created. Changing this forces a new resource to be created.

• dns_servers - (Optional) List of IP addresses of DNS servers

• subnet - (Optional) Can be specified multiple times to define multiple subnets. Each subnet block supports fields documented below.

• tags - (Optional) A mapping of tags to assign to the resource.

The subnet block supports:

• name - (Required) The name of the subnet.

• address_prefix - (Required) The address prefix to use for the subnet.

• security_group - (Optional) The Network Security Group to associate with the subnet. (Referenced by id, ie. azurerm_network_security_group.test.id)

Attributes Reference

The following attributes are exported:

• id - The virtual NetworkConfiguration ID.

• name - The name of the virtual network.

• resource_group_name - The name of the resource group in which to create the virtual network.

• location - The location/region where the virtual network is created

• address_space - The address space that is used the virtual network.

Import

Virtual Networks can be imported using the resource id, e.g.

terraform import azurerm_virtual_network.testNetwork /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/mygroup1/providers/Microsoft.Network/virtualNetworks/myvnet1
