我的 nginx.conf 在本地按预期工作，没有错误，但是当移动到此应用服务环境时，我收到下面概述的错误。
我正在使用 Azure App Service multi-container (preview) app in Web App for Containers 开发一个基于 TypeScript 构建的 React 应用程序，但在使用 NGINX 时遇到了一些问题。当我尝试运行应用服务时，我收到的主要错误是一些错误日志:
- “connect() 失败(111:连接被拒绝)”
- “连接到上游时没有实时上游”
应用服务 > 设置 > 配置 下的我的 WEBSITES_PORT 设置为 80。我还尝试将其设置为80:80。在这两种情况下，我都会得到下面相同的错误日志。将 WEBSITES_PORT 设置为 3001 并从容器设置文件中的服务列表中删除 nginx 会导致应用服务部署成功。
除了以下文件之外，如果我还可以提供其他文件，请告诉我。
我的容器设置在应用服务 > 设置 > 容器设置下找到，指向存储我的所有应用程序镜像的私有(private) Azure 容器注册表。该结构与我用于本地部署的 docker compose 文件非常相似。
version: '3.3'
services:
mysite:
image: "reactapp.azurecr.io/my_site_img"
ports:
- "3001:3001"
nginx:
image: "reactapp.azurecr.io/nginx"
ports:
- "80:80"
一个nginx.conf，用于控制我的 nginx 镜像中的路由。
upstream my_site_proxy {
server localhost:3001;
}
server {
listen 0.0.0.0:80;
server_name localhost;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://my_site_proxy/;
proxy_redirect off;
}
}
当我尝试使用上述配置运行 Azure 应用服务时生成的错误日志文件。

最佳答案
您需要将 nginx 上游配置更改为:
upstream my_site_proxy {
server mysite:3001;
}
您应该连接到 mysite，这是您的应用容器的名称。 Docker 会将此 DNS 名称解析为应用程序容器的 IP 地址。如果您在同一容器内运行 nginx 和您的应用程序，则只能连接到 localhost(这不是最佳实践。)
