c# - 在 C#.Net 控制台应用程序中通过 Kubernetes API 执行命令“ConnectGetNamespacedPodExec”时出现“BadRequest”错误

Question

我正在开发一个控制台 C#.Net 工具来通过其 API 访问 Kubernetes，我能够连接到命名空间和 Pod，但我无法在 Pod 内执行命令。当我到达最后一行代码时收到错误“BadRequest”，可能是命令“ConnectGetNamespacedPodExec”的参数有问题。如果有人可以帮助我，我将不胜感激。

KubernetesClientConfiguration myConfig = new KubernetesClientConfiguration();
myConfig.SkipTlsVerify = true;
myConfig.Host = "https://myURL.com";
myConfig.ClientCertificateData = "Removed";
myConfig.ClientCertificateKeyData = "Removed";

var k8sClient = new Kubernetes(myConfig);

//List Namespaces
var NameSpacesList = k8sClient.ListNamespace();
foreach (var item in NameSpacesList.Items)
{
    Console.WriteLine(item.Metadata.Name);
}

//List Pods
var PodsList = k8sClient.ListNamespacedPod(NameSpacesList.Items[5].Metadata.Name); //Karam
foreach (var item in PodsList.Items)
{
    Console.WriteLine(item.Metadata.Name);
}

//This is where the error happens
var str = k8sClient.ConnectGetNamespacedPodExec(name: PodsList.Items[0].Metadata.Name, namespaceParameter: NameSpacesList.Items[5].Metadata.Name, command:"ls", stderr: true, stdin: false, stdout: true, tty: true);
        

我得到的错误：

mscorlib.dll 中出现“Microsoft.Rest.HttpOperationException”类型的未处理异常。附加信息：操作返回无效状态代码“BadRequest”
