c# - Dotnet 5 Kubernetes TLS 在生产中失败

Question

我一直在使用自签名证书在 prod 中运行我的 dotnet 3 应用程序，但升级到 dotnet 5 kestrel 后无法启动并出现以下错误。我的服务器证书由中间 CA 签名，该 CA 也包含在 Kubernetes pod 中。可以使用额外的一组眼睛。
这是我的 StartUp.cs

public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                    webBuilder.ConfigureKestrel((context, serverOptions) =>
                    {
                        var config = context.Configuration;
                        certificate = new X509Certificate2(config["CERT"], config["PASS"]);


                        Log.Information($"found certificate {certificate.Subject}");
                        serverOptions.ConfigureHttpsDefaults(listenOptions =>
                        {
                            listenOptions.ServerCertificate = certificate;
                        });
                    });
                });

这是我在 pod 启动时出现的错误。

Answer 1

找到了解决办法，只好在pod中添加CA证书(crt)，中间证书不足以满足证书链。希望它可以帮助其他人获得上述异常。
