docker容器C#应用程序外部的连接被拒绝

我在C#.Net内核（v3.1）中有一个应用程序，当我运行它时。它很好用

当我在docker容器中启动它时，它在容器中运行良好，但在尝试调用容器外部的端点时，我遇到了一个错误

连接被拒绝

我的命令

docker build . -t project
docker run project -p 23183:23183

我的程序.cs

using System.IO;
using Microsoft.AspNetCore.Hosting;

namespace project
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var host = new WebHostBuilder()
                .UseContentRoot(Directory.GetCurrentDirectory())
                .UseKestrel()
                .UseStartup<Startup>()
                .Build();

            host.Run();
        }
    }
}

不确定你的问题到底是什么，但这就是我的docker文件的样子。希望有帮助：

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base

WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build
WORKDIR /src
COPY ["path/to/project.csproj", "project/"]
COPY . .
WORKDIR "/src/project"

FROM build AS publish
RUN dotnet publish "project.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "project.dll"]

我认为您必须在入口点数组（Dockerfile）中使用

--URL

作为参数@stefan我试过了，但没有让我明白这一点-您无法从本地pc访问

localhost:23183

上的API？@rytisk是的。为什么您不；'t调用dotnet restore？如果愿意，您可以，但对我来说，它是在构建步骤中完成的抱歉，它实际上是在

运行dotnet发布

步骤中完成的

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 as base
COPY . /app
WORKDIR /app
EXPOSE 23183/tcp
ENV ASPNETCORE_URLS http://*:23183

# Build
FROM base as build
WORKDIR /src
COPY *.sln ./
COPY project/project.csproj project/

RUN dotnet restore
COPY . .
WORKDIR /src/project

# Publish
FROM build AS publish
RUN dotnet publish -c Release -o /app/out

FROM base AS final
WORKDIR /app
COPY --from=publish /app/out ./
ENTRYPOINT ["dotnet", "project.dll", "--server.urls", "http://0.0.0.0:23183"]

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base

COPY ["path/to/project.csproj", "project/"]
