创建域、项目、用户和角色¶

The Identity service provides authentication services for each OpenStack service. The authentication service uses a combination of domains, projects, users, and roles.

1. 本指南使用一个你添加到你的环境中每个服务包含独有用户的service 项目。创建``service``项目：

   $ openstack project create --domain default \
     --description "Service Project" service
   
   +-------------+----------------------------------+
   | Field       | Value                            |
   +-------------+----------------------------------+
   | description | Service Project                  |
   | domain_id   | default                          |
   | enabled     | True                             |
   | id          | 24ac7f19cd944f4cba1d77469b2a73ed |
   | is_domain   | False                            |
   | name        | service                          |
   | parent_id   | default                          |
   +-------------+----------------------------------+
   

2. 常规（非管理）任务应该使用无特权的项目和用户。作为例子，本指南创建 demo 项目和用户。

   • 创建``demo`` 项目：

     $ openstack project create --domain default \
       --description "Demo Project" demo
     
     +-------------+----------------------------------+
     | Field       | Value                            |
     +-------------+----------------------------------+
     | description | Demo Project                     |
     | domain_id   | default                          |
     | enabled     | True                             |
     | id          | 231ad6e7ebba47d6a1e57e1cc07ae446 |
     | is_domain   | False                            |
     | name        | demo                             |
     | parent_id   | default                          |
     +-------------+----------------------------------+
     

     注解

     当为这个项目创建额外用户时，不要重复这一步。

   • 创建``demo`` 用户：

     $ openstack user create --domain default \
       --password-prompt demo
     
     User Password:
     Repeat User Password:
     +---------------------+----------------------------------+
     | Field               | Value                            |
     +---------------------+----------------------------------+
     | domain_id           | default                          |
     | enabled             | True                             |
     | id                  | aeda23aa78f44e859900e22c24817832 |
     | name                | demo                             |
     | password_expires_at | None                             |
     +---------------------+----------------------------------+
     

   • 创建 user 角色：

     $ openstack role create user
     
     +-----------+----------------------------------+
     | Field     | Value                            |
     +-----------+----------------------------------+
     | domain_id | None                             |
     | id        | 997ce8d05fc143ac97d83fdfb5998552 |
     | name      | user                             |
     +-----------+----------------------------------+
     

   • 添加 user``角色到 ``demo 项目和用户：

     $ openstack role add --project demo --user demo user
     

     注解

     这个命令执行后没有输出。
