第 8 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。
8.1. 创建 Overcloud Tenant 网络
Overcloud 需要为实例提供一个 Tenant 网络。source
overcloud 并在 Neutron 中创建一个初始的网络。例如：
$ source ~/overcloudrc $ neutron net-create default $ neutron subnet-create --name default --gateway 172.20.1.1 default 172.20.0.0/16
这会创建一个名为
default 的基本 Neutron 网络。Overcloud 会使用一个内部的 DHCP 来从这个网络中自动分配 IP 地址。
使用
neutron net-list 来确定创建的网络：
$ neutron net-list +-----------------------+-------------+----------------------------------------------------+ | id | name | subnets | +-----------------------+-------------+----------------------------------------------------+ | 95fadaa1-5dda-4777... | default | 7e060813-35c5-462c-a56a-1c6f8f4f332f 172.20.0.0/16 | +-----------------------+-------------+----------------------------------------------------+
