import io.kubernetes.client.openapi.ApiClient;

import io.kubernetes.client.openapi.Configuration;
import io.kubernetes.client.openapi.apis.CoreV1Api;
import io.kubernetes.client.openapi.models.V1NodeList;
import io.kubernetes.client.util.Config;

public class KubernetesClientExample {
    public static void main(String[] args) throws ApiException {
        // 创建Kubernetes客户端
        ApiClient client = Config.defaultClient();
        Configuration.setDefaultApiClient(client);

        // 创建CoreV1Api对象
        CoreV1Api api = new CoreV1Api();

        // 调用API获取节点列表
        V1NodeList nodeList = api.listNode(null, null, null, null, null, null, null, null, null);
        System.out.println("Nodes:");
        for (V1Node node : nodeList.getItems()) {
            System.out.println(node.getMetadata().getName());
        }
    }
}
