Creating floating IPs

POST /v2.0/floatingips

Create a floating IP.

You can obtain the required floating_network_id and subnet_id from a request to v2.0/networks?provider:physical_network=Public.

The status will change to ACTIVE after a while.

Request

Parameters

Name	In	Type	Description
`floatingip`	body	object	A `floatingip` object. When you associate a floating IP address with a VM, the instance has the same public IP address each time that it boots, basically to maintain a consistent IP address for maintaining DNS assignment.
`description` (Optional)	body	string	A human-readable description for the resource. Default is an empty string.
`dns_domain` (Optional)	body	string	A valid DNS domain.
`dns_name` (Optional)	body	string	A valid DNS name.
`tenant_id`	body	string	The ID of the project.
`project_id`	body	string	The ID of the project.
`floating_network_id`	body	string	The ID of the network associated with the floating IP.
`fixed_ip_address` (Optional)	body	string	The fixed IP address that is associated with the floating IP. If an internal port has multiple associated IP addresses, the service chooses the first IP address unless you explicitly define a fixed IP address in the `fixed_ip_address` parameter.
`floating_ip_address` (Optional)	body	string	The floating IP address.
`port_id` (Optional)	body	string	The ID of a port associated with the floating IP. To associate the floating IP with a fixed IP at creation time, you must specify the identifier of the internal port.
`subnet_id` (Optional)	body	string	The subnet ID on which you want to create the floating IP.

Response

Parameters

Name	In	Type	Description
`floatingip`	body	object	A `floatingip` object. When you associate a floating IP address with a VM, the instance has the same public IP address each time that it boots, basically to maintain a consistent IP address for maintaining DNS assignment.
`id`	body	string	The ID of the floating IP address.
`router_id`	body	string	The ID of the router for the floating IP.
`status`	body	string	The status of the floating IP. Values are `ACTIVE`, `DOWN` and `ERROR`.
`description`	body	string	A human-readable description for the resource.
`dns_domain`	body	string	A valid DNS domain.
`dns_name`	body	string	A valid DNS name.
`port_details`	body	string	The information of the port that this floating IP associates with. In particular, if the floating IP is associated with a port, this field contains some attributes of the associated port, including `name`, `network_id`, `mac_address`, `admin_state_up`, `status`, `device_id` and `device_owner`. If the floating IP is not associated with a port, this field is `null`.
`tenant_id`	body	string	The ID of the project.
`created_at`	body	string	The date and time when the resource was created. The date and time stamp format is ISO 8601: CCYY-MM-DDThh:mm:ss±hh:mm For example, `2015-08-27T09:49:58-05:00`. The `±hh:mm` value, if included, is the time zone as an offset from UTC. In this example, the offset value is `-05:00`.
`updated_at`	body	string	The date and time when the resource was updated. If the resource has not been updated, this field will be `null`. The date and time stamp format is ISO 8601: CCYY-MM-DDThh:mm:ss±hh:mm For example, `2015-08-27T09:49:58-05:00`. The `±hh:mm` value, if included, is the time zone as an offset from UTC. In this example, the offset value is `-05:00`.
`revision_number`	body	integer	The revision number of the resource.
`project_id`	body	string	The ID of the project.
`floating_network_id`	body	string	The ID of the network associated with the floating IP.
`fixed_ip_address`	body	string	The fixed IP address that is associated with the floating IP address.
`floating_ip_address`	body	string	The floating IP address.
`port_id`	body	string	The ID of a port associated with the floating IP.
`tags`	body	array	The list of tags on the resource.
`port_forwardings`	body	array	The associated port forwarding resources for the floating IP. If the floating IP has multiple port forwarding resources, this field has multiple entries. Each entry consists of network IP protocol (`protocol`), the fixed IP address of internal neutron port (`internal_ip_address`), the TCP or UDP port used by internal neutron port (`internal_port`) and the TCP or UDP port used by floating IP (`external_port`).

Status codes

Success

Code	Reason
`201 - Created`	Resource was created and is ready to use.

Error

Code	Reason
`400 - Bad Request`	Some content in the request was invalid.
`401 - Unauthorized`	User must authenticate before making a request.
`404 - Not Found`	The requested resource could not be found.
`409 - Conflict`	This operation conflicted with another operation on this resource.

The operation returns the Bad Request (400) response code for one of reasons:

The network is not external, such as router:external=False.

The internal OpenStack Networking port is not associated with the floating IP address.

The requested floating IP address does not fall in the subnet range for the external network.

The fixed IP address is not valid.

If the port ID is not valid, this operation returns 404 response code.

The operation returns the Conflict (409) response code for one of reasons:

The requested floating IP address is already in use.
The internal OpenStack Networking port and fixed IP address are already associated with another floating IP.
