Kubernetes 上的 Nginx（99：无法分配请求的地址）

Question

所以我有我的应用程序的服务，并希望 nginx 代理到它的连接。我使用 IP 地址告诉 nginx 哪个是应用程序的服务节点端口（100.68.202.75）。问题是当豆荚启动时它给了我：

2019/05/25 17:32:38 [emerg] 1#1：bind() 到 100.71.178.70:443 失败（99：无法分配请求的地址） nginx: [emerg] bind() to 100.71.178.70:443 failed (99: Cannot assign requested address)

应用程序在具有服务的不同部署上单独运行。我只想告诉听那个服务。所以它可以重定向流量。

您应该将listen 100.68.202.75:443; 替换为listen 443 ssl;。 Pod IP 是动态的，每次重启时都会发生变化。
