docker compose aspnetcore build vs dotnet run

Question

通过 docker (compose) 运行 dotnetcore 应用程序不会像通过“dotnet run”那样解决。

我使用 dotnet build 运行它，dotnet run 它出现“正在侦听 https://localhost:44301”并将其放入我引用的 Debug 文件夹中。来自 docker 的相同目录显示“正在侦听 https://[::]:44301”，但尝试进入站点启动页面时出现 500 错误。

这是我当前的 Dockerfile：

FROM mcr.microsoft.com/dotnet/core/sdk:3.1
COPY mydir/myproj /app
WORKDIR /app

RUN dotnet restore -nowarn:3202,nu1503 -p:RestoreUseSkipNonexistantTargets=false 

RUN dotnet build 
EXPOSE 44301/tcp
ENV ASPNETCORE_URLS=https://*:44301

WORKDIR /app/bin/Debug/netcoreapp3.1/
ENTRYPOINT ["dotnet", "myproj.dll"]

这实际上是当前尝试调试此问题的文件。任何“解决”差异的帮助将不胜感激。

试试这个，您需要将 {APPFOLDER} 和 {DLLNAME} 替换为您的设置：

    FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build
    WORKDIR /app
    COPY ./{APPFOLDER} .
    WORKDIR /openssl
    COPY ./somecert.pfx .
    
    WORKDIR /app/{APPFOLDER}/
    RUN dotnet publish -c Release -r linux-x64 -o out /p:publishsinglefile=true /p:publishtrimmed=true
    
    FROM mcr.microsoft.com/dotnet/core/runtime-deps:3.1 AS runtime
    WORKDIR /openssl
    COPY --from=build /openssl/somecert.pfx ./    
    WORKDIR /app
    COPY --from=build /app/{APPFOLDER}/out ./
    ENTRYPOINT ["./{DLLNAME}"]

然后您可以使用它来构建它：

docker build -f .\Dockerfile C:\Git\WHEREMYAPPIS\ -t somename/myapp:latest

然后运行它：

docker run -p 5100:80 somename/myapp:latest


WebHost.CreateDefaultBuilder(args)
    .UseKestrel(options =>
    {
        options.Listen(IPAddress.Loopback, 5000);  // http:localhost:5000
        options.Listen(IPAddress.Any, 80);         // http:*:80
        options.Listen(IPAddress.Loopback, 443, listenOptions =>
        {
            listenOptions.UseHttps("certificate.pfx", "password");
        });
    })
    .UseStartup<Startup>()
    .Build();
