DC/OS文档通过在 Admin Router 和来自群集外部的用户代理程序请求之间 设置代理，您可以使用自定义服务器证书与 DC/OS 群集建立安全的 HTTPS 通信。HTTP 代理必须执行即时 HTTP 请求和响应标头修改，因为 DC/OS 不知道用户代理程序用于寻址 HTTP 代理的自定义主机名和端口。
在 Admin Router 前配置 HAProxy
使用 HAProxy 在 DC/OS [Admin Router] 前设置 HTTP 代理。(/mesosphere/dcos/cn/2.0/overview/architecture/components/#admin-router). 如果您想向通过 HTTPS 连接到群集的用户代理程序提供自定义服务器证书，这可能非常有用。DC/OS 当前不支持将您自己的证书直接添加到 Admin Router 中。
以下说明提供了经测试的 HAProxy 配置示例，其处理命名请求/响应重写。此示例确保 HAProxy 和 DC/OS Admin Router 之间的通信是 TLS 加密的。
注意：您可以使用代理 IP 地址 DNS 条目找到您的任务 IP。
<taskname>.<framework_name>.agentip.dcos.thisdcos.directory
其中：
-
taskname：任务名称。 -
framework_name：框架名称，如果您不确定，则可能是marathon。global daemon log 127.0.0.1 local0 log 127.0.0.1 local1 notice maxconn 20000 pidfile /var/run/haproxy.pid defaults log global option dontlog-normal mode http retries 3 maxconn 20000 timeout connect 5000 timeout client 50000 timeout server 50000 frontend http # Bind on port 9090.
