我正在使用 Java 客户端来获取其中一个部署的副本数。这就是我使用的方式。我的k8s版本是1.18,java kubernetes客户端版本是10.0.0

  KubeClient kubeClient = new KubeClient();
      kubeClient.getReplicas();

public class KubeClient {
        public void getReplicas() throws IOException, ApiException {
            ApiClient client = Config.defaultClient();
            Configuration.setDefaultApiClient(client);
            AppsV1Api appsV1Api = new AppsV1Api(client);
            V1Scale v1Scale = appsV1Api.readNamespacedDeploymentScale("mydeployment", "mynamespace", null);
            System.out.println("no of replicas is :  "+v1Scale.getSpec().getReplicas());
        }
    }

当我调用appsV1Api.readNamespacedDeploymentScale("mydeployment", "mynamespace", null);时出现异常
