Allow to specify floating IP address

Launchpad blueprint:

https://blueprints.launchpad.net/neutron/+spec/allow-specific-floating-ip-address

Problem Description

IP Address of floating ip is automatically allocated from IP pool.

In some cases, user want to specify a IP Address of floating ip.

Proposed Change

Adding the floating ip address as an attribute to the API for creating floating ip. An attribute name is floating_ip_address.

Attributes of API are limited by "policy.json". By default, Non-admin user cannot use floating_ip_address. Admin can use it. ("rule:admin_only")

Alternatives

None

Data Model Impact

None

REST API Impact

  • floating_ip_address will be allowed to POST /v2.0/floatingips
  • It is not updatable. i.e. cannot use for PUT /v2.0/floatingips

The attribute map will be changed as the following.

RESOURCE_ATTRIBUTE_MAP = {
    ...
    'floatingips': {
        ...
        'floating_ip_address': {'allow_post': True, 'allow_put': False,
                                'validate': {'type:ip_address_or_none': None},
                                'is_visible': True, 'default': None,
                                'enforce_policy': True},
        ...
    },
    ...
}

Security Impact

An administrator of OpenStack should consider whether this feature is exposed to tenant user.

If users have a permission to use this feature, Users can control public ip addresses.
