docker nginx ERR_NAME_NOT_RESOLVED
docker nginx ERR_NAME_NOT_RESOLVED
运行 4 docker 个容器：server/client/nginx/mongo 反向代理
客户端似乎在端口 4200 上工作，我可以看到我的应用程序和路由工作。
尝试注册用户时，我请求下面的 httpclient post 到名为 "myserver" 的 Docker 容器，它应该调用 api。
我收到此 DNS 错误消息。
在 resolv.conf 查看 NGINX 容器时（它显示 127.0.0.11）这是正确的 dns Docker 解析容器内的 dns-es。
当我从容器内 ping 到另一个容器的名称时，它起作用了。
当我从服务器端口 3000 上的容器内部和外部远程登录时，它的工作原理与客户端端口 4200 上的远程登录一样好
那么当我尝试在我的网站上注册帐户时无法解析 myserver 的原因可能是什么。
几乎就像是从容器外部调用 register 一样，所以它无法解析它，这是正常行为吗？

使用反向代理连接到容器时，应用程序使用的所有 URL 都需要指向该反向代理而不是应用程序。通常，您通过在 URL 中提供一个没有主机名的路径来做到这一点。如果您计划使用基于虚拟路径的反向代理，您需要更进一步并在 URL 中使用相对路径。这一切都需要在应用程序发送给客户端的响应中发生。
