红帽全球峰会第 7 章 创建 Overcloud 后执行的任务
本章介绍了在创建 Overcloud 后需要执行的任务。
7.1. 创建 Overcloud External 网络

在基本的使用情景和高级的使用情景中，我们配置了节点接口来使用 External 网络。但是，我们仍然需要在 Overcloud 中创建这个网络，从而可以为实例分配浮动 IP 地址。这个过程假设 External 网络有一个专用的接口或原生 VLAN。
Source
overcloud，并在 Neutron 中创建一个外部网络：
source ~/overcloudrc neutron net-create nova --router:external --provider:network_type flat --provider:physical_network datacentre neutron subnet-create --name nova --enable_dhcp=False --allocation-pool=start=10.1.1.51,end=10.1.1.250 --gateway=10.1.1.1 nova 10.1.1.0/24
$ source ~/overcloudrc
$ neutron net-create nova --router:external --provider:network_type flat --provider:physical_network datacentre
$ neutron subnet-create --name nova --enable_dhcp=False --allocation-pool=start=10.1.1.51,end=10.1.1.250 --gateway=10.1.1.1 nova 10.1.1.0/24
使用
neutron net-list 确定创建的网络：
