Navigating around openstack networks

fog.md

Given a router, get the attached external gateway's pool name:

floating_ip_pool_name = network.networks.get(router.external_gateway_info["network_id"]).name
# => "IO.IP"

Use the pool name to provision a floating IP:

compute.addresses.create(pool: floating_ip_pool_name)

The list of Networks that are external gateways (and have floating IPs):

network.networks.select {|n| n.router_external}
# => <Fog::Network::OpenStack::Networks
    filters={}
    [
      <Fog::Network::OpenStack::Network
