我nginx.conf在本地按预期工作，没有错误，但是当移动到这个应用服务环境时，我得到了下面列出的错误。

我正在使用Web App for Containers 中的 Azure App Service 多容器（预览版）应用程序开发基于 TypeScript 的 React 应用程序，但遇到了 NGINX 的一些问题。我得到的主要错误是一些错误日志，当我尝试运行应用服务时会这样说：

  • “连接（）失败（111：连接被拒绝）”
  • “连接到上游时没有实时上游”

我的WEBSITES_PORT下App Service > Settings > Configuration设置为80. 我也尝试将其设置为80:80. 在这两种情况下，我都会在下面得到相同的错误日志。WEBSITES_PORT在容器设置文件的服务列表中设置3001和删除 nginx 会导致应用服务部署成功。

让我知道除了下面的文件之外，我是否可以提供其他文件。

我的容器设置App Service > Settings > Container Settings指向我的私有 Azure 容器注册表，该注册表存储了我的所有应用程序映像。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控制我的 nginx 映像中的路由。

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我的 Azure 应用服务时生成的错误日志文件。

您需要将您的 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 名称解析为应用容器的 IP 地址。如果您在同一个容器中运行 nginx 和您的应用程序，您只会连接到localhost（这不是最佳实践。）
