Question

我需要使用dotnet core和nginx代理服务器。我有两个简单的图像和docker撰写文件。 Dotnet应用程序适用于正确的端口。但是当我和nginx一起使用时，我认为是80的地图。 Nginx抛出错误502。

我的步骤：

从https://github.com/jwilder/nginx-proxy
使用以下命令创建dotnet应用图片： docker build --no-cache = true -t dotnetcoreimage。
docker-compose up

这是我的app langsettings：

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://*:5000/",
      "sslPort": 0
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "IIS Express (Production)": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Production"
      }
    }
  }
}

App Docker文件：

# FROM microsoft/dotnet:latest
FROM microsoft/aspnetcore-build

#Update everytihing
RUN apt-get -qq update && apt-get -qq -y install bzip2

#remove force apt lists
RUN rm -rf /var/lib/apt/lists/*

#for secure, copy to app folder
COPY . /app

RUN rm -Rf /app/node_modules

RUN rm -Rf /app/bower_components

#set workdir
WORKDIR /app

#set ASPNETCORE_ENVIRONMENT to Production
ENV ASPNETCORE_ENVIRONMENT "Production"

#restore packages
RUN ["dotnet", "restore"]

#build c#
RUN ["dotnet", "build"]

#npm install dependencies (webpack etc.)
RUN ["npm", "install"]

#run npm task webpack-prod
RUN ["npm", "run", "webpack-prod"]

EXPOSE 5000/tcp

# command to run
CMD ["dotnet", "run", "--server.urls", "http://*:5000"]

当你运行时： docker-compose up 并转到 http://localhost

我认为，该网络应用程序有错误的端口映射，因为80应该有nginx吗？（现在听取：http://+:80）

我尝试 docker composive --force-recreate ，停止/启动docker并重新启动pc，但同样的问题。

请问哪里有问题？谢谢你的时间。
