红帽全球峰会3.4. 默认镜像导入块列表和允许列表设置
glance-image-import.conf 文件是一个可选文件，包含以下默认选项：
- allowed_schemes - [http, https]
- disallowed_schemes - empty list
- allowed_hosts - 空列表
- disallowed_hosts - 空列表
- allowed_ports - [80, 443]
- disallowed_ports - empty list
如果您使用默认值，最终用户只能使用 http 或 https 方案访问 URI。用户可以指定的唯一端口为 80 和 443。用户不必指定端口，但如果是端口，则必须为 80 或 443。
您可以在镜像服务源代码树的 etc/ 子目录中找到 glance-image-import.conf 文件。确保您正在查找 Red Hat OpenStack Platform 发行版本的正确分支。
