运行4个docker容器：server / client / nginx / mongo reverse-proxy 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。 在尝试注册用户时，我正在请求下面的httpclient帖子到名为“myserver”的Docker容器，该容器应该调用api。 我收到此DNS错误消息。
查看resolv.conf中的NGINX容器（显示127.0.0.11），这是正确的dns Docker在容器内解析dns-es。 当我从容器内ping到另一个容器的名称时，它可以工作。 当我从服务器端口3000上的容器内部和外部远程登录时，它可以在客户端的端口4200上进行远程登录 因此，当我尝试在我的网站上注册帐户时，可能导致无法解析myserver的原因。 这几乎就好像寄存器的调用是从容器外部进行的，所以无法解决它，这是正常行为吗？
let url = 'http://myserver:3000/api/register';

评论回答：
当使用反向代理连接到容器时，应用程序使用的所有URL都需要指向反向代理而不是应用程序。通常，您通过在URL中提供没有主机名的路径来执行此操作。如果您打算使用基于虚拟路径的反向代理，则需要更进一步，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。
