openstack_networking_subnet_v2

Manages a V2 Neutron subnet resource within OpenStack.

Example Usage

resource "openstack_networking_network_v2" "network_1" {
  name = "tf_test_network"
  admin_state_up = "true"
}

resource "openstack_networking_subnet_v2" "subnet_1" {
  network_id = "${openstack_networking_network_v2.network_1.id}"
  cidr = "192.168.199.0/24"
}

Argument Reference

The following arguments are supported:

• region - (Required) The region in which to obtain the V2 Networking client. A Networking client is needed to create a Neutron subnet. If omitted, the OS_REGION_NAME environment variable is used. Changing this creates a new subnet.

• network_id - (Required) The UUID of the parent network. Changing this creates a new subnet.

• cidr - (Required) CIDR representing IP range for this subnet, based on IP version. Changing this creates a new subnet.

• ip_version - (Optional) IP version, either 4 (default) or 6. Changing this creates a new subnet.

• name - (Optional) The name of the subnet. Changing this updates the name of the existing subnet.

• tenant_id - (Optional) The owner of the subnet. Required if admin wants to create a subnet for another tenant. Changing this creates a new subnet.

• allocation_pools - (Optional) An array of sub-ranges of CIDR available for dynamic allocation to ports. The allocation_pool object structure is documented below. Changing this creates a new subnet.

• gateway_ip - (Optional) Default gateway used by devices in this subnet. Leaving this blank and not setting no_gateway will cause a default gateway of .1 to be used. Changing this updates the gateway IP of the existing subnet.

• no_gateway - (Optional) Do not set a gateway IP on this subnet. Changing this removes or adds a default gateway IP of the existing subnet.

• enable_dhcp - (Optional) The administrative state of the network. Acceptable values are “true” and “false”. Changing this value enables or disables the DHCP capabilities of the existing subnet. Defaults to true.

• dns_nameservers - (Optional) An array of DNS name server names used by hosts in this subnet. Changing this updates the DNS name servers for the existing subnet.

• host_routes - (Optional) An array of routes that should be used by devices with IPs from this subnet (not including local subnet route). The host_route object structure is documented below. Changing this updates the host routes for the existing subnet.

• value_specs - (Optional) Map of additional options.

The allocation_pools block supports:

• start - (Required) The starting address.

• end - (Required) The ending address.

The host_routes block supports:

• destination_cidr - (Required) The destination CIDR.

• next_hop - (Required) The next hop in the route.
