訪問kubernetes集群有幾下幾種方式：

使用client-go獲取Deployment列表：

package main

import (
    "path/filepath"
    "k8s.io/client-go/tools/clientcmd"
    "k8s.io/client-go/kubernetes"
    "k8s.io/apimachinery/pkg/apis/meta/v1"
    "fmt"
)

func main() {
    path, err := filepath.Abs("./
 
")
    if err != nil {
        panic(err)
    }
    configFilePath := path + "/K8s/API/config"

    // use the config file
    config, err := clientcmd.BuildConfigFromFlags("", configFilePath)
    if err != nil {
        panic(err.Error())
    }
    
    // NewForConfig creates a new ClientSet for the given config.
    clientSet, err :
 
= kubernetes.NewForConfig(config)
    if err != nil {
        panic(err.Error())
    }
    
    // get all deployment in default namespace
    deploymentList, err := clientSet.AppsV1().Deployments("default").List(v1.ListOptions{})
    if err != nil {
        panic(err.Error())
    }

    // print list deployment name and replicas
    for _, v := range deploymentList.Items {
        fmt.Printf(" * %s (%d replicas)\n", v.Name, *v.Spec.Replicas)
    }

}
