为什么带Docker的.NET核心模板应用程序在Docker创建的IP地址上不响应

asp.net-core docker

user5389726598465 · 技术社区 · 6 年前

我正在使用.NET Core中的“添加Docker支持”选项,并具有以下自动生成的启动设置:

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:49800",
      "sslPort": 44327
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "WebApplication1": {
      "commandName": "Project",
      "launchBrowser": true,
      "applicationUrl": "https://localhost:5001;http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

下面是 docker-compose.override.yml

version: '3.4'

services:
  webapplication1:
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
      - ASPNETCORE_URLS=https://+:443;http://+:80
      - ASPNETCORE_HTTPS_PORT=44327
    ports:
      - "49800:80"
      - "44327:443"
    volumes:
      - ${APPDATA}/ASP.NET/Https:C:\Users\ContainerUser\AppData\Roaming\ASP.NET\Https:ro
      - ${APPDATA}/Microsoft/UserSecrets:C:\Users\ContainerUser\AppData\Roaming\Microsoft\UserSecrets:ro
networks:
  default:
    external:
      name: nat

Docker正在自动打开它创建的IP地址 https://172.20.167.220/ 它会超时。

Dockerfile的顶部看起来像:

FROM microsoft/dotnet:2.1-aspnetcore-runtime-nanoserver-sac2016 AS base
WORKDIR /app
EXPOSE 49800
EXPOSE 44327
EXPOSE 443 #I added this line as an experiment

我不确定实际使用的IP地址和端口,因为launchsettings.json没有“Docker”配置文件,但启动应用程序的唯一方法是从“调试播放”按钮中选择Docker。此应用程序是由Docker MVC核心模板创建的。这将调用program.cs中的createDefaultBuilder,因此Kestrel运行在localhost:5000/50001上,我假设它通过默认生成器创建的IISIntegration映射到端口49800和44327,然后Docker应该映射到端口80和443,映射到一些非标准IP地址,然后打开。我应该在Docker打开防火墙端口吗?

我怀疑我可能做错了什么,在这里我硬编码了安全证书 Program.cs 以下内容:

   public static IWebHostBuilder CreateWebHostBuilder(string[] args ) =>
            WebHost.CreateDefaultBuilder(args).UseKestrel(options=>
            {
                options.Listen(IPAddress.Loopback, 5000);
                options.Listen(IPAddress.Loopback, 5001, listenOptions =>
                {
                    listenOptions.UseHttps(@"C:\Users\ContainerUser\AppData\Roaming\ASP.NET\Https\WebApplication1.pfx", "bede5cf6-6b63-427a-8576-d3a137f51070");
                });
            }

)

我连接到容器,Docker设置中的某些内容不正确,因为在运行netstat时端口443上没有任何内容在侦听,而中间IIS似乎也没有在49800/44327上运行。以下内容:

C:\app>netstat -a -b -n -o
