Floating IP Reservation¶
Prerequisites¶
The following packages should be installed:
blazar
neutron
python-blazarclient
The floating IP plugin should be enabled in blazar.conf:
[manager]
plugins = virtual.floatingip.plugin
1. Create reservable floating IPs¶
The operator should create floating IPs as reservable resources using the floatingip-create command. They must select floating IPs that are not part of an allocation pool in Neutron. For example, to create a reservable floating IP with address
172.24.4.2from the Neutron network with ID81fabec7-00ae-497a-b485-72f4bf187d3e, run:
blazar floatingip-create 81fabec7-00ae-497a-b485-72f4bf187d3e 172.24.4.2
Check reservable floating IPs:
blazar floatingip-list
Result:
+--------------------------------------+---------------------+--------------------------------------+
| id | floating_ip_address | floating_network_id |
+--------------------------------------+---------------------+--------------------------------------+
| 67720c36-4d53-41e6-acec-7d3fb9436fd5 | 172.24.4.2 | 81fabec7-00ae-497a-b485-72f4bf187d3e |
+--------------------------------------+---------------------+--------------------------------------+
2. Create a lease¶
Create a lease (floating IP reservation) using the lease-create command. Note that
python-blazarclientversion 2.2.1 or greater is required to use this feature. When you useresource_type=virtual:floatingip, the following parameters are supported:network_id: UUID of the external network to reserve from (required)amount: number of floating IPs to reserve (optional, defaults to 1)required_floatingips: list of specific floating IPs to allocate (optional, must be formatted as a JSON array)
blazar lease-create --reservation 'resource_type=virtual:floatingip,network_id=81fabec7-00ae-497a-b485-72f4bf187d3e,amount=2,required_floatingips=["172.24.4.2","172.24.4.3"]' fip-lease
Result:

3. Update a lease¶
Update a lease (floating IP reservation) using the lease-update command. Note that
python-blazarclientversion 2.2.1 or greater is required to use this feature. After passing the existing reservation ID to the--reservationoption, you can modify start or end dates as well as some reservation parameters:amount: you can modify the number of floating IPs to reserve. Reducingamountis supported only for pending reservations.required_floatingips: you can only reset the list of specific floating IPs to allocate to an empty list
blazar lease-update --reservation 'id=e80033e6-5279-461d-9573-dec137233434,amount=3,required_floatingips=[]' fip-lease
Result:

4. Use the leased resources¶
Once the lease becomes active, the allocated floating IPs are tagged with the reservation ID, in this case
e80033e6-5279-461d-9573-dec137233434, and can be displayed with the following command:
openstack floating ip list --tags reservation:e80033e6-5279-461d-9573-dec137233434
Result:
+--------------------------------------+---------------------+------------------+------+--------------------------------------+----------------------------------+
| ID | Floating IP Address | Fixed IP Address | Port | Floating Network | Project |
+--------------------------------------+---------------------+------------------+------+--------------------------------------+----------------------------------+

| ae26069c-f7e9-4b8d-8ca0-6770c025dfae | 172.24.4.3 | None | None | 81fabec7-00ae-497a-b485-72f4bf187d3e | 10b4b88b67e141aeb093fec48c93232c |
| b427c171-30fe-45c4-a00b-3d5ca9b00306 | 172.24.4.2 | None | None | 81fabec7-00ae-497a-b485-72f4bf187d3e | 10b4b88b67e141aeb093fec48c93232c |
+--------------------------------------+---------------------+------------------+------+--------------------------------------+----------------------------------+
Use the reserved floating IP like a regular one, for example by attaching it to an instance with
openstack server add floating ip.
