c# - 调用K8S API时修复 “The credentials supplied to the package were not recognized”

Question

我有一个使用https://github.com/kubernetes-client/csharp中的库调用Kubernetes REST API的客户端。传递客户端证书凭据时，出现以下错误:

System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception. ---> System.ComponentModel.Win32Exception: The credentials supplied to the package were not recognized

我怎样才能解决这个问题？

解决此问题的技巧是在私钥上配置属性。特别是，需要设置X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.Exportable标志。

var context = Yaml.LoadFromString<K8SConfiguration>(configFileInRawYaml);
var config = KubernetesClientConfiguration.BuildConfigFromConfigObject(context);
config.ClientCertificateKeyStoreFlags = X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.Exportable;
var client = new Kubernetes(config);
