kubernetes集群中是否有获取节点容量的API或go编程逻辑？

package main

import (
    "fmt"
    "k8s.io/client-go/kubernetes"
    "k8s.io/client-go/tools/clientcmd"
    "k8s.io/client-go/util/homedir"
    "path/filepath"
)

func main() {
    // 获取kubeconfig文件路径
    home := homedir.HomeDir()
    kubeconfig := filepath.Join(home, ".kube", "config")

    // 加载kubeconfig文件
    config, err := clientcmd.BuildConfigFromFlags("", kubeconfig)
    if err != nil {
        panic(err.Error())
    }

    // 创建Kubernetes客户端
    clientset, err := kubernetes.NewForConfig(config)
    if err != nil {
        panic(err.Error())
    }

    // 获取所有节点
    nodes, err := clientset.CoreV1().Nodes().List(context.TODO(), metav1.ListOptions{})
    if err != nil {
        panic(err.Error())
    }

    // 打印节点容量信息
    for _, node := range nodes.Items {
        fmt.Printf("Node: %s\n", node.Name)
        fmt.Printf("Capacity: %v\n", node.Status.Capacity)
    }
}
