启动容器

在包含容器服务的环境中，您可以启动一个容器。

1. 获取 demo 凭证，以非管理项目身份执行以下步骤

   $ . demo-openrc
   

2. 确定可用的网络。

   $ openstack network list
   +--------------------------------------+-------------+--------------------------------------+
   | ID                                   | Name        | Subnets                              |
   +--------------------------------------+-------------+--------------------------------------+
   | 4716ddfe-6e60-40e7-b2a8-42e57bf3c31c | selfservice | 2112d5eb-f9d6-45fd-906e-7cabd38b7c7c |
   | b5b6993c-ddf9-40e7-91d0-86806a42edb8 | provider    | 310911f6-acf0-4a47-824e-3032916582ff |
   +--------------------------------------+-------------+--------------------------------------+
   

   注意

   此输出可能与您的环境不同。

3. 设置 NET_ID 环境变量以反映网络的 ID。例如，使用 selfservice 网络

   $ export NET_ID=$(openstack network list | awk '/ selfservice / { print $2 }')
   

4. 在 selfservice 网络上运行 CirrOS 容器

   $ openstack appcontainer run --name container --net network=$NET_ID cirros ping 8.8.8.8
   

5. 稍后，验证容器是否成功创建

   $ openstack appcontainer list
   +--------------------------------------+-----------+--------+---------+------------+-------------------------------------------------+-------+
   | uuid                                 | name      | image  | status  | task_state | addresses                                       | ports |
   +--------------------------------------+-----------+--------+---------+------------+-------------------------------------------------+-------+
   | 4ec10d48-1ed8-492a-be5a-402be0abc66a | container | cirros | Running | None       | 10.0.0.11, fd13:fd51:ebe8:0:f816:3eff:fe9c:7612 | []    |
   +--------------------------------------+-----------+--------+---------+------------+-------------------------------------------------+-------+
   

6. 访问容器并验证对互联网的访问

   $ openstack appcontainer exec --interactive container /bin/sh
   # ping -c 4 openstack.org
   # exit
   

7. 停止并删除容器。

   $ openstack appcontainer stop container
   $ openstack appcontainer delete container
