background ：

It's done client-go gin Simple integration of ten -Update, Let's demonstrate namespace deployment pod The deletion of , After the deletion is completed, you can also summarize and conduct more in-depth operations ！ Delete from pod deployment namespace The sequence begins ！

delete Pod

With nginx Pod For example

Be careful ：zhangpeng namespace Next nginx pod For example

[[email protected] k8s]$ kubectl get pods -n zhangpeng
NAME                        READY   STATUS    RESTARTS   AGE
nginx                       1/1     Running   0          113s
zhangpeng-5546976d9-mkslb   1/1     Running   0          102m
zhangpeng-5546976d9-tcsb5   1/1     Running   0          101m

Write about pod delete Code for

Continue to imitate create update Write delete Method , Actually delete It only needs namespace and pod Of name That's all right. , To simplify the ：
/src/service/Pod.go

func DeletePod(g *gin.Context) {
	var NewPod Pod
	if err := g.ShouldBind(&NewPod); err != nil {
		g.JSON(500, err)
	}
	err := K8sClient.CoreV1().Pods(NewPod.Namespace).Delete(context.TODO(), NewPod.Name, metav1.DeleteOptions{})
	if err != nil {
		fmt.Println(err)
	}
	g.JSON(200, "ok")
}

delete deployment

With zhangpeng deployment For example

With namespace zhangpeng Under the namespace zhangpeng** deployment** For example

[[email protected] k8s]$ kubectl get pods -n zhangpeng
NAME                        READY   STATUS    RESTARTS   AGE
zhangpeng-5546976d9-mkslb   1/1     Running   0          124m
zhangpeng-5546976d9-tcsb5   1/1     Running   0          123m
[[email protected] k8s]$ kubectl get deployment -n zhangpeng
NAME        READY   UP-TO-DATE   AVAILABLE   AGE
zhangpeng   2/2     2            2           141m

func DeleteDep(g *gin.Context) {
	var newDep Deployment
	if err := g.ShouldBind(&newDep); err != nil {
		g.JSON(500, err)
	}
	err := K8sClient.AppsV1().Deployments(newDep.Namespace).Delete(context.Background(), newDep.Name, metav1.DeleteOptions{})
	if err != nil {

default           Active   54d
kube-node-lease   Active   54d
