Nginx在码头内的反向代理不符合上游端口设置
Nginx在码头内的反向代理不符合上游端口设置
提问于 2019-10-11 00:54:56
我正在尝试使用正式的nginx映像(https://hub.docker.com/_/nginx)来服务静态内容，并将代理反向代理到另一个停靠容器中的api服务器。它们都是由坞-组合调用带来的，因此它们应该是同一个网络的一部分。
当我查看日志时，我看到这样的错误，其中nginx无法与上游服务器对话。我担心的是，我看到了http://localhost/users?sort=lastName%2Cdesc，看起来它没有遵守上游的端口设置，这当然会失败。我不知道应该如何配置才能使其与之匹配。我读过的所有指南都有uri声明和上游url声明的组合，不管有没有尾斜杠，这些都不能满足我的需要。
7#7：*3在连接上游时没有活动的上行流，客户端: 10.0.2.2，服务器: localhost，请求："GET /api/user?sort=lastName%2Cdesc HTTP/1.1"，上游："http://localhost/users?sort=lastName%2Cdesc"，主机："localhost"，引用者："http://localhost/“

API在8081上
客户端在8080上
客户端应该将/api/*的任何内容转发给8081码头http://localhost:8081/，并删除/api/部分。

将所有静态html复制到/usr/share/nginx/html，将配置复制到/etc/nginx/nginx.conf中。

不能使用localhost引用不同的容器地址。您可以将容器想象成一个单独的机器，显然使用localhost不会让您连接到邻居或朋友的计算机。当两台机器在同一个网络中时，您可以使用它们对应的网络ips或主机名在它们之间创建通信。
它在码头的工作原理完全一样。如果您想连接到同一网络中的其他容器，则需要使用它的ip (可以通过docker network inspect <NETWORK_NAME>)或主机名(在本例中是与容器名称相同的主机名)。
所以您的nginx.conf而不是：
location /api/ {
proxy_pass http://localhost:8081/;
}应包括：
location /api/ {
proxy_pass http://API_CONTAINER_NAME:8081/;
