||
# azurerm_virtual_network | ||
|
||
Use this data source to access the properties of an Azure Virtual Network. | ||
|
||
## Example Usage | ||
|
||
```hcl | ||
data "azurerm_virtual_network" "test" { | ||
name = "production" | ||
resource_group_name = "networking" | ||
} | ||
|
||
output "virtual_network_id" { | ||
value = "${data.azurerm_virtual_network.test.id}" | ||
} | ||
``` | ||
|
||
## Argument Reference | ||
|
||
* `name` - (Required) Specifies the name of the Virtual Network. | ||
* `resource_group_name` - (Required) Specifies the name of the resource group the Virtual Network is located in. | ||
|
||
## Attributes Reference | ||
|
||
* `id` - The ID of the virtual network. | ||
* `address_spaces` - The list of address spaces used by the virtual network. | ||
* `dns_servers` - The list of DNS servers used by the virtual network. | ||
* `subnets` - The list of name of the subnets that are attached to this virtual network. | ||
* `vnet_peerings` - A mapping of name - virtual network id of the virtual network peerings. |
