Docker nginx can'；t连接到单独容器中运行的上游gunicorn

我尝试了各种选项，例如，

expose

，

bridge

，

docker compose的
networks
选项，但无法使其与在单独容器中运行的上游gunicorn的nginx连接一起工作，我收到了来自nginx的
502坏网关
错误。我不确定我到底错过了什么。下面是我的

整个代码可以在github上以及存储库中找到，以便您轻松测试。
Gunicon配置：

bind = '127.0.0.1:8000'

这将绑定到
loopback
接口（仅限本地主机），将其更改为
0.0.0
以绑定到容器中的每个可用接口。这将使它可以从nginx访问

Nginx配置：

upstream worker {
    server 127.0.0.1:8000;
}

您需要将worker容器的
环回
ip更改为
DNSname/ip
。我建议创建一个用户定义的网络，然后将所有相关的容器放在该网络中，并通过DNS名称调用它们。您在默认网桥网络中没有内部DNS，因此以下nginx配置将不起作用

upstream worker {
    server worker:8000;
}

nginx位于哪里？在单独的容器中还是在web容器中？@FarhadFarahi
nginx
在
web
container
gunicorn
在
worker
容器中。您可以访问整个代码，非常感谢，我尝试了
服务器工作者：8000，但从未更改gunicorn中的绑定地址。没问题，请注意，默认网络中不会有内部dns。
