你好，我想马上说的是，我一直在使用docker-compose和nginx没有这么长时间，对不起，如果你会看到一些错误，从我自己的。
我遇到了nginx设置的问题，现在几天都解决不了。我的任务是使用docker-compose连接到我本地comp上的另一个容器。在第一个容器中，我使用反向代理，将我的请求转发到另一个容器，并运行xboxyterlab。但当我连接到xboxyter时，我总是得到**502 Bad Gateway**，但这两个容器运行。也许xboxyter不需要，但是在反向代理中的应用程序
我假设问题出在我的docker-compose网络上，但我使用了不同的方法，但不幸的是，我总是遇到同样的问题
所以我的docker-compose看起来像这样

version: '3.8'

services:
    jupyterlab:
        build:
            ...
        volumes:
            - ...
        ports:
            - "8888:8888"
        networks:
            - new-networks

    nginx:
        build:
            ...
        ports:
            - "80:80"
        networks:
            - new-networks

                - subnet: 127.0.0.0/16

字符串
在Jupyter的Dockerfile中，我有EXPOSE 8888
在nginx容器中，我使用sites-enable文件名为domain（所以127.0.0.1），而不是nginx.conf（但在这个任务中，我也使用了nginx.conf，但我得到了相同的错误）
我在nginx中的设置（文件名：127.0.0.1）：

upstream backend {
        server 127.0.0.1:8888;
}

server {
        listen 80;
        listen [::]:80;

        root /var/www/127.0.0.1/html;
        index index.html index.htm index.nginx-debian.html;

        server_name 127.0.0.1 www.127.0.0.1 ;

        location /jupyter {
                proxy_pass http://backend/;
        }

        location /status {
                default_type application/json;
                return 200 '{"status": "All good"}';
        }
}

我尝试在upstream和proxy_pass中使用另一个域（如172...）。尝试set_headers。更改ufw（但不太多）。但总是相同的错误（502）。
我在nginx中检查了我的日志（如果在upstream中我写127.0.0.1：8888），它得到：

connect() failed (111: Connection refused) while connecting to upstream, client: 172.18.0.1, server: 127.0.0.1, request: "GET /jupyter HTTP/1.1", upstream: "http://127.0.0.1:8888/", host: "127.0.0.1"

型
当我写172...：8888 un upstream（here I got 404 error）：

*2 open() "/var/www/127.0.0.1/html/lab" failed (2: No such file or directory), client: 172.18.0.1, server: 127.0.0.1, request: "GET /lab? HTTP/1.1", host: "127.0.0.1"

型

upd.2

我也试过用途：

upstream backend {
        server jupyterlab:8888;

型
但我只得到404

*6 open() "/var/www/127.0.0.1/html/lab" failed (2: No such file or directory), client: 172.20.0.1, server: 127.0.0.1, request: "GET /lab? HTTP/1.1", host: "127.0.0.1"

型

upd.3

现在我改变了我的nginx conf文件，现在get another 404不像往常一样。

upstream jupyter {
        server jupyterlab:8888;
}

server {
        listen nginx:80;

        server_name 127.0.0.1 www.127.0.0.1 ;

        location /jupyter {
                proxy_pass http://jupyter;
        }

        location /ping {
                default_type application/json;
                return 200 '{"status": "All good"}';
        }
}
