红帽全球峰会14.3. 配置 ALLOWED_HOSTS
Horizon 基于 python Django Web 框架构建，需要对与误导 HTTP 主机标头相关的安全威胁进行保护。若要应用此保护，请将 ALLOWED_HOSTS 设置配置为使用 OpenStack 控制面板提供的 FQDN。
当您配置 ALLOWED_HOSTS 设置时，任何带有与此列表中值不匹配的 HTTP 请求都会被拒绝，并引发错误。
流程
在模板中的
parameter_defaults下，设置HorizonAllowedHosts参数的值：parameter_defaults: HorizonAllowedHosts: <value>parameter_defaults: HorizonAllowedHosts: <value>Copy to Clipboard Copied! Toggle word wrap Toggle overflow 将
<value>替换为 OpenStack 仪表板提供的 FQDN。- 使用修改后的模板以及您的环境所需的所有其他模板，部署 overcloud。
