浮动 IP 预留¶
先决条件¶
应安装以下软件包
blazar
neutron
python-blazarclient
浮动 IP 插件应在 blazar.conf 中启用
[manager]
plugins = virtual.floatingip.plugin
1. 创建可预留的浮动 IP¶
操作员应使用 floatingip-create 命令将浮动 IP 创建为可预留资源。他们必须选择 Neutron 中不在分配池中的浮动 IP。例如，要从 ID 为
81fabec7-00ae-497a-b485-72f4bf187d3e的 Neutron 网络创建地址为172.24.4.2的可预留浮动 IP，请运行
# Using the blazar CLI
blazar floatingip-create 81fabec7-00ae-497a-b485-72f4bf187d3e 172.24.4.2
# Using the openstack CLI
openstack reservation floatingip create 81fabec7-00ae-497a-b485-72f4bf187d3e 172.24.4.2
检查可预留的浮动 IP
# Using the blazar CLI
blazar floatingip-list
# Using the openstack CLI
openstack reservation floatingip list
结果
+--------------------------------------+---------------------+--------------------------------------+
| id | floating_ip_address | floating_network_id |
+--------------------------------------+---------------------+--------------------------------------+
| 67720c36-4d53-41e6-acec-7d3fb9436fd5 | 172.24.4.2 | 81fabec7-00ae-497a-b485-72f4bf187d3e |
+--------------------------------------+---------------------+--------------------------------------+
2. 创建租赁¶
使用 lease-create 命令创建租赁（浮动 IP 预留）。请注意，使用此功能需要
python-blazarclient版本 2.2.1 或更高版本。当您使用resource_type=virtual:floatingip时，支持以下参数network_id：要从中预留的外部网络的 UUID（必需）amount：要预留的浮动 IP 数量（可选，默认为 1）required_floatingips：要分配的特定浮动 IP 列表（可选，必须格式化为 JSON 数组）
# Using the blazar CLI
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
# Using the openstack CLI
openstack reservation 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
结果

3. 更新租赁¶
使用 lease-update 命令更新租赁（浮动 IP 预留）。请注意，使用此功能需要
python-blazarclient版本 2.2.1 或更高版本。在将现有的预留 ID 传递给--reservation选项后，您可以修改开始或结束日期以及一些预留参数amount：您可以修改要预留的浮动 IP 数量。仅支持减少amount以进行待处理的预留。required_floatingips：您只能将要分配的特定浮动 IP 列表重置为空列表
# Using the blazar CLI
blazar lease-update --reservation 'id=e80033e6-5279-461d-9573-dec137233434,amount=3,required_floatingips=[]' fip-lease
# Using the openstack CLI
openstack reservation lease update --reservation 'id=e80033e6-5279-461d-9573-dec137233434,amount=3,required_floatingips=[]' fip-lease
结果
Updated lease: fip-lease
检查更新后的租赁
# Using the openstack CLI
blazar lease-show fip-lease
# Using the openstack CLI
openstack reservation lease show fip-lease

4. 使用租赁的资源¶
一旦租赁变为活动状态，分配的浮动 IP 将被标记为预留 ID，在本例中为
e80033e6-5279-461d-9573-dec137233434，可以使用以下命令显示
openstack floating ip list --tags reservation:e80033e6-5279-461d-9573-dec137233434
结果
+--------------------------------------+---------------------+------------------+------+--------------------------------------+----------------------------------+
| ID | Floating IP Address | Fixed IP Address | Port | Floating Network | Project |
+--------------------------------------+---------------------+------------------+------+--------------------------------------+----------------------------------+
| 3954b799-4957-4e9f-96b7-46f72604c973 | 172.24.4.4 | None | None | 81fabec7-00ae-497a-b485-72f4bf187d3e | 10b4b88b67e141aeb093fec48c93232c |
| 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 |
+--------------------------------------+---------------------+------------------+------+--------------------------------------+----------------------------------+
像使用常规浮动 IP 一样使用预留的浮动 IP，例如通过使用
openstack server add floating ip将其附加到实例。
