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：
- 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：
- 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......
