无法从Docker网络外部连接容器内的沙盒

Question

我正在尝试在Docker容器中设置Orleans silo。一开始，客户端不会在容器中。

我正在使用Linux容器模式下的Windows上的Docker。 当客户端也在容器中时，我可以让客户端和silo同时运行并连接。

silo配置如下：

var builder = new SiloHostBuilder()
                .Configure<ClusterOptions>(options =>
                {
                    options.ClusterId = "DOCKER-SILO";
                    options.ServiceId = "EZ-DOCKER";
                })
                .UseAdoNetClustering(options =>
                {
                    options.Invariant = "MySql.Data.MySqlClient";
                    options.ConnectionString = "server=XXX;user id=orleans;password='XXX';persistsecurityinfo=True;database=orleans;SslMode=None";
                })
                .Configure<EndpointOptions>(options =>
                {
                    var adressList = Dns.GetHostEntry(Dns.GetHostName()).AddressList;
                    options.AdvertisedIPAddress = adressList.First();
                    options.GatewayPort = 30000);
                    options.SiloPort = 11111);
                })

客户端配置如下：

client = new ClientBuilder()
                .Configure<ClusterOptions>(options =>
                {
                    options.ClusterId = "DOCKER-SILO";
                    options.ServiceId = "EZ-DOCKER";
                })
                .UseStaticClustering(new IPEndPoint(IPAddress.Parse("192.168.0.13"), 30000))

这个筒仓是这样运行的：

PS C:\XXX> docker run -p 30000:30000 --expose 11111 --add-host host.docker.internal:192.168.0.13 ezorleanssilolinux

Dockerfile 相当简单：

FROM mcr.microsoft.com/dotnet/core/runtime:2.1-stretch-slim AS base
WORKDIR /app

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

当我在客户端中使用127.0.0.1作为静态网关IP时，它能够正常工作。但是，如果使用docker主机的任何其他IP，则会在仓储日志中出现以下错误：

Gateway received unexpected non-proxied connection from *sgn/01111111-1111-1111-1111-111111111111/11111111 at source address 172.17.0.1:38428

当我在本地地址以外的任何其他地址进行尝试时，为什么会出现此错误？netstat -n -a显示该容器正在主机上监听0.0.0.0。

以上是否可以包含您的Dockerfile中的一些或全部内容？ - seniorquico

几个小时后，我成功地让所有东西都正常工作了，来看看我的筒仓代码：

 return new HostBuilder()
                .UseOrleans(builder =>
                {
                    builder
                        .UseDashboard()
                        .UseAdoNetClustering(options =>
                        {
                            options.Invariant = "System.Data.SqlClient";
                            options.ConnectionString = _connectionString;
                        })
                        .Configure<EndpointOptions>(options =>
                        {
                            // Port to use for Silo-to-Silo
                            options.SiloPort = 11111;
                            // Port to use for the gateway
                            options.GatewayPort = 30000;
                            // IP Address to advertise in the cluster
                            options.AdvertisedIPAddress = IPAddress.Parse(GetExternalIpAddress());
                            // The socket used for silo-to-silo will bind to this endpoint
                            options.GatewayListeningEndpoint = new IPEndPoint(IPAddress.Any, 40000);
                            // The socket used by the gateway will bind to this endpoint
                            options.SiloListeningEndpoint = new IPEndPoint(IPAddress.Any, 50000);
                        })
                        .Configure<ClusterOptions>(options =>
                        {
                            options.ClusterId = "ClusterId-ForSign";
                            options.ServiceId = "ServiceId-ForSign";
                        })
                        .ConfigureApplicationParts(parts =>
                        {
                            parts.AddApplicationPart(typeof(UserService).Assembly).WithReferences();
                            parts.AddApplicationPart(typeof(CompanyService).Assembly).WithReferences();
                        });
                })
                .ConfigureServices(services =>
                {
                    services.AddTransient<ICompanyRepository, CompanyRepository>();
                    services.AddTransient<ICompanyService, CompanyService>();
                    services.Configure<ConsoleLifetimeOptions>(options =>
                    {
                        options.SuppressStatusMessages = true;
                    });
                })
                .ConfigureLogging(builder =>
                {
                    builder.AddConsole();
                })
                .RunConsoleAsync();
        }

GetExternalIpAddress() => new WebClient().DownloadString("https://api.ipify.org");，但您希望它在Orleans客户端中可解析。另请参见https://github.com/dotnet/orleans/issues/8268。 - BozoJoe
