问题描述
我正在使用 Java 客户端来获取其中一个部署的副本计数。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
@H_404_2@ KubeClient kubeClient = new KubeClient();
kubeClient.getReplicas();
@H_404_2@
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",null) 时遇到异常；
