我有一个Kestrel服务器,它将Hello World
返回给任何HTTP请求。
static class Program
{
static void Main(string[] args)
{
var webHostBuilder = WebHost.CreateDefaultBuilder(args)
.UseSetting("applicationName", "Hello World")
.Configure(builder => {
builder.Run(async context =>
{
var textBytes = UTF8.GetBytes("Hello World!");
await context.Response.Body.WriteAsync(textBytes, 0, textBytes.Length, default (CancellationToken));
});
})
.UseUrls("http://+:8000");
var webHost = webHostBuilder.Build();
webHost.Run();
}
}
我已将构建程序集添加到Docker镜像并使用此DockerFile
构建它:
FROM microsoft/dotnet
WORKDIR /app
ADD /application /app
EXPOSE 8000
ENTRYPOINT [ "dotnet", "hello-world-server.dll" ]
我用它来运行它:
>docker run hello-world-server --publish-list 8000:8000
当我向http://localhost:8000
发送请求时,我会返回502。
我在Windows 10上使用Windows容器。
构建和完整的输出运行如下:
C:\...\hello-world-server-docker>docker build -t hello-world-server .

当向localhost:8000
发出请求时,来自Kestrel的控制台上没有进一步的输出,而通常会有普通的控制台应用程序。
我也试过用>docker run hello-world-server --publish 8000:8000
运行它。
答案 0 :(得分:1)
我认为问题出在docker run命令中。 --publish-list 8000:8000
就像现在一样,是容器入口点的参数。
运行容器并公开端口的命令是:
docker run -p 8000:8000 hello-world-server
docker run
的每个命令行选项必须放在之前图像名称。 图像名称后的所有内容都是容器本身的命令。
