如何在运行时从Go代码获取Pod外部IP

片刻后我找到了答案，但完全忘了在这里发布！

请注意，如果您不在Kubernetes环境中，它将崩溃

import (    metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"    "k8s.io/client-go/kubernetes"    "k8s.io/client-go/rest"    "os"    "os/signal"    "time")//// Pod infos//func GetPodDetails() (IP string, name string) {    // creates the in-cluster config    config, err := rest.InClusterConfig()    if err != nil {        panic(err.Error())    }    // creates the clientset    clientset, err := kubernetes.NewForConfig(config)    if err != nil {        panic(err.Error())    }    IP = ""    for {        if IP != "" { break        } else { log.Printf("No IP for now.n")        }        pods, err := clientset.CoreV1().Pods("default").List(metav1.ListOptions{})        if err != nil { panic(err.Error())        }        for _, pod := range pods.Items { pod, _ := clientset.CoreV1().Pods("default").Get(pod.Name, metav1.GetOptions{}) if pod.Name == os.Getenv("HOSTNAME") {     IP = pod.Status.PodIP }        }        log.Printf("Waits...n")        time.Sleep(1 * time.Second)    }    name = os.Getenv("HOSTNAME")    log.Printf("Trying os.Getenv("HOSTNAME/IP"): [%s][%s]n", name, IP)    return IP, name}
