Symfony Docker dotnet core nginx代理502

我需要使用dotnetcore和nginx代理服务器。我有两个简单的图像和docker compose文件。Dotnet应用程序使用正确的端口运行良好。但当我将它与nginx一起使用时，我认为它是映射到80的。Nginx抛出错误502

我的步骤：

从以下位置创建docker compose文件：

使用：docker build--no cache=true-t dotnetcoreimage创建dotnet应用程序映像

码头工人整理

以下是我的应用程序设置：

{
  "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"
      }
    }
  }
}

应用程序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"]

docker compose.yml

version: '2'
services:
  nginx-proxy:
    image: jwilder/nginx-proxy
    container_name: nginx-proxy
    ports:
      - "80:80"
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro

  mujcykloweb:
    image: mujcykloweb
    container_name: mujcyklowebcontainer       
    environment:
      - VIRTUAL_HOST=localhost

运行时：docker撰写并转到

我认为，那个web应用程序的端口映射不好，因为80是否应该有nginx？（现在收听：）

我尝试了docker Compositive——强制重新创建、停止/启动docker并重新启动pc，但同样的问题

请问问题在哪里？

感谢您抽出时间。

Dockerfile公开5000端口和应用程序侦听5000端口。好的

EXPOSE 5000/tcp CMD[“dotnet”，“run”，“--server.url”，“http://*：5000”]

但为什么您在什么时候运行应用程序it listen 80端口

mujcyklowebcontainer |现在收听：http://+：80

我很困惑。谢谢你的回答。我也很困惑，因为没有编写，只有dotnet运行正确的列表端口。也许是docker的缓存？我不知道。让我们尝试向docker comose公开应用程序端口。尝试添加

mujcykloweb:port:-5000:5000

您有权访问

http://localhost:5000

来自主机？不，我得到：加载资源失败：我的浏览器中出现net:：ERR\u EMPTY\u响应。嗯，有人正在监听5000端口。可能是你的应用程序？你的应用程序有访问日志吗？当您公开5000端口时，请让我们尝试通过nginx访问您的应用程序。
