验证操作¶

使用 `CirrOS <http://launchpad.net/cirros>`__对镜像服务进行验证，CirrOS是一个小型的Linux镜像可以用来帮助你进行 OpenStack部署测试。

For more information about how to download and build images, see OpenStack Virtual Machine Image Guide. For information about how to manage images, see the OpenStack End User Guide.

1. 获得 admin 凭证来获取只有管理员能执行的命令的访问权限：

   $ . admin-openrc
   

2. 下载源镜像：

   $ wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img
   

   注解

   如果您的发行版里没有包含wget，请安装它

3. 使用 QCOW2 磁盘格式， bare 容器格式上传镜像到镜像服务并设置公共可见，这样所有的项目都可以访问它：

   $ openstack image create "cirros" \
     --file cirros-0.3.5-x86_64-disk.img \
     --disk-format qcow2 --container-format bare \
     --public

   注解

   OpenStack 是动态生成 ID 的，因此您看到的输出会与示例中的命令行输出不相同。

4. 确认镜像的上传并验证属性：

   $ openstack image list
