# openstack\_networking\_network\_v2
|
||||
|
||||
Use this data source to get the ID of an available OpenStack network.
|
||||
|
||||
## Example Usage
|
||||
|
||||
```
|
||||
data "openstack_networking_network_v2" "network" {
|
||||
name = "tf_test_network"
|
||||
}
|
||||
```
|
||||
|
||||
## Argument Reference
|
||||
|
||||
* `region` - (Required) The region in which to obtain the V2 Neutron client.
|
||||
A Neutron client is needed to retrieve networks ids. If omitted, the
|
||||
`OS_REGION_NAME` environment variable is used.
|
||||
|
||||
* `name` - (Optional) The name of the network.
|
||||
|
||||
* `matching_subnet_cidr` - (Optional) The CIDR of a subnet within the network.
|
||||
|
||||
* `tenant_id` - (Optional) The owner of the network.
|
||||
|
||||
## Attributes Reference
|
||||
|
||||
`id` is set to the ID of the found network. In addition, the following attributes
|
||||
are exported:
|
||||
|
||||
* `admin_state_up` - (Optional) The administrative state of the network.
|
||||
* `name` - See Argument Reference above.
|
||||
* `region` - See Argument Reference above.
|
||||
* `shared` - (Optional) Specifies whether the network resource can be accessed
|
||||
by any tenant or not.
