mongodb - Rancher MongoDB Replica Set 暴露master

Question

我已经从 Rancher 目录安装了 MongoDB 副本集，并且启动良好。下一个合乎逻辑的事情是公开 master，以便我可以配置和使用它。我已经看到我可以使用负载平衡器公开 27017 TCP 端口，但是这将循环而不是与 mongo 主服务器有关联。

Rancher有没有办法只暴露主人？

根据本文概述了这种方法，请考虑为此使用 HAProxy：

listen mongodb_cluster
 bind 10.0.0.10:27017
 option tcp-check
