client-go连接kubernetes集群-delete相关操作

背景

紧跟client-go连接kubernetes集群-connect and list，client-go连接kubernetes集群-create相关操作与client-go连接kubernetes集群-update相关操作。现在操作一下删除deployment 与namespace。当然了也想看一下操作集群crud的操作都有哪些动作！

client-go连接kubernetes集群-delete相关操作

删除deployment

main.go

package main

import (
    "context"
    "flag"
    "fmt"
    metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
    "k8s.io/client-go/kubernetes"
    "k8s.io/client-go/tools/clientcmd"
    "k8s.io/client-go/util/homedir"
    "path/filepath"
)

func main() {
    var kubeconfig *string
    if home := homedir.HomeDir(); home != "" {
        kubeconfig = flag.String("kubeconfig", filepath.Join(home, ".kube", "config"), "(optional) absolute path to the kubeconfig file")
    } else {
        kubeconfig = flag.String("kubeconfig", "", "absolute path to the kubeconfig file")
    }
    flag.Parse()
    config, err := clientcmd.BuildConfigFromFlags("", *kubeconfig)
    if err != nil {
        panic(err.Error())
    }

    // create the clientset
    clientset, err := kubernetes.NewForConfig(config)
    if err != nil {
        panic(err.Error())
    }
    DeploymentName := "nginx"
    if err = clientset.AppsV1().Deployments("zhangpeng").Delete(context.TODO(), DeploymentName, metav1.DeleteOptions{}); err != nil {
        fmt.Println(err)
        return
    }
}

kubectl get deploymnt -n zhangpeng 

删除namespace

main.go

package main

import (
    "context"
    "flag"
    "fmt"
    metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
    "k8s.io/client-go/kubernetes"
    "k8s.io/client-go/tools/clientcmd"
    "k8s.io/client-go/util/homedir"
    "path/filepath"
)

func main() {
    var kubeconfig *string
    if home := homedir.HomeDir(); home != "" {
        kubeconfig = flag.String("kubeconfig", filepath.Join(home, ".kube", "config"), "(optional) absolute path to the kubeconfig file")
    } else {
        kubeconfig = flag.String("kubeconfig", "", "absolute path to the kubeconfig file")
    }
    flag.Parse()
    config, err := clientcmd.BuildConfigFromFlags("", *kubeconfig)
    if err != nil {
        panic(err.Error())
    }

    // create the clientset
    clientset, err := kubernetes.NewForConfig(config)
    if err != nil {
        panic(err.Error())
    }
    NamespaceName := "zhangpeng"
    if err = clientset.CoreV1().Namespaces().Delete(context.TODO(), NamespaceName, metav1.DeleteOptions{}); err != nil {
        fmt.Println(err.Error())
        return
    } else {
        fmt.Printf("Deleted Namespaces %s\n", NamespaceName)
    }
}

kubectl get ns

zhangpeng namespace删除成功！

其他的：

1. 当然了除了常用的List delete update and create还有很多操作方法，比如namespace 与 deployment的一些其他操作：

2. 接下来要做的:把客户端单独提取出来，跟gin整合做一些简单的crud操作......
