client-go连接kubernetes集群-delete相关操作

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

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......
