docker - docker 中的 ASP.net 核心 gRPC 服务回复错误的 ssl 证书

Question

我创建了一个 gRPC WebService (netcoreapp3.1)，它托管在使用 C# 的 docker 容器中。它在本地运行良好。
我使用以下 dockerfile 进行 docker 构建:

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1
# USER ContainerAdministrator
WORKDIR /app
EXPOSE 443

WORKDIR /app
COPY publish .

ENTRYPOINT ["dotnet", "MyService.dll"]

在 Ubuntu 20.4 机器上，我通过以下方式启动容器

docker run --rm -it -p 32555:443 -e ASPNETCORE_URLS="https://+" -e ASPNETCORE_HTTPS_PORT=443 -e ASPNETCORE_Kestrel__Certificates__Default__Password=secretpassword -e ASPNETCORE_Kestrel__Certificates__Default__Path=/https/ourdomain.de.pfx  -v /home/user/.aspnet/https:/https/ myservice

这会产生以下输出

info: Microsoft.Hosting.Lifetime[0]
      Now listening on: https://[::]:443
info: Microsoft.Hosting.Lifetime[0]
      Application started. Press Ctrl+C to shut down.
info: Microsoft.Hosting.Lifetime[0]
      Hosting environment: Production
info: Microsoft.Hosting.Lifetime[0]
      Content root path: /app

ourdomain.de.pfx 是我的管理员为我们的域创建的。
如果我从客户端调用服务，我会得到一个执行

Error on call 'CreateGaebAsync' with SSL certificate check: Status(StatusCode=Internal, Detail="Error starting gRPC call. HttpRequestException: The SSL connection could not be established, see inner exception. AuthenticationException: The remote certificate is invalid according to the validation procedure.")

为了获得更多信息，我向 GrpcChannel 添加了一个 HttpClientHandler

    private GrpcChannel CreateGrpcChannelWithDangerousIgnoreSslCertificate()
            {
                var httpHandler = new HttpClientHandler();
                httpHandler.ServerCertificateCustomValidationCallback = DangerousServerCertificateCustomValidationCallback;
                var httpClient = new HttpClient(httpHandler);
                return GrpcChannel.ForAddress(serviceUri, new GrpcChannelOptions() { HttpClient = httpClient });
            }
    private bool DangerousServerCertificateCustomValidationCallback(HttpRequestMessage arg1, X509Certificate2 arg2, X509Chain arg3, SslPolicyErrors arg4)
        {
            Console.WriteLine(arg1);
            Console.WriteLine("X509Certificate2:");
            Console.WriteLine(arg2);
            Console.WriteLine("X509Chain:");
            Console.WriteLine(arg3);
            Console.WriteLine("SslPolicyErrors:");
            Console.WriteLine(arg4);
            // No check of Certificate is done so this will accept any response.
            // For production this has to be fixed by acceptiong only valid SSL certificates!!!
            return true;
        }

验证回调生成以下输出

Method: POST, RequestUri: 'https://computername.ourdomain.de:32555/mysvc.TextService/CreateText',
    Version: 2.0, Content: Grpc.Net.Client.Internal.PushUnaryContent`2[MyService.CreateTextRequest,MyService.CraeteTextReply],

我希望看到来自 ourdomain.de.pfx 的证书信息，但我得到的似乎暗示 ASPNETCORE_Kestrel__Certificates__Default__Path=/https/ourdomain.de.pfx 给出的证书被忽略了？!
我几乎没有证书的经验...
如果我使用错误的密码或 pfx 的错误名称启动容器，我会收到相应的错误消息。所以在我看来，网络服务应该使用正确的。
因为我不确定是否必须设置容器内的端口(443)或主机的映射端口(32555)，所以我改变了

 ASPNETCORE_HTTPS_PORT=443

经过

ASPNETCORE_HTTPS_PORT=32555

当运行 docker 容器没有成功时。
你能解释一下，我错过了什么，好吗？

Answer 1

除了你自己，不要相信任何人。

我从原始文件重新生成了 ubuntu 主机上的 pfx，并且 SSL 连接按预期工作。

sudo openssl pkcs12 -export -out certificate.pfx -inkey certificate.key -in certificate.crt
