How to delete all custom resources of a kind in k8s cluster (all namespaces) using client-go
问题
我正在尝试使用client-go在k8s集群中删除特定类型的资源。
我正在使用以下代码，但它需要声明一个特定的命名空间，但我想在所有命名空间中删除此资源。
u.SetName("test")u.SetNamespace(v1.NamespaceAll)u.SetGroupVersionKind(schema.GroupVersionKind{Group: "group",Kind: "kind",Version: "v1",})err := k8sClient.Delete(context.TODO(), u)if err != nil {fmt.Println(err.Error())return err}
在这里找到了示例 - https://pkg.go.dev/sigs.k8s.io/controller-runtime/pkg/client
但它没有提到关于所有命名空间的内容。
请问有人可以提供一种解决方法吗？
注意：
这是自定义资源，不是默认的类型，如pod或deployment等。

I'm trying to delete resources of a particular kind in a k8s cluster using client-go.
I'm using this code but it requires a specific namespace to be declared, but i want to delete this resource in all namespaces.
u.SetName("test")u.SetNamespace(v1.NamespaceAll)u.SetGroupVersionKind(schema.GroupVersionKind{Group: "group",Kind: "kind",Version: "v1",})err := k8sClient.Delete(context.TODO(), u)if err != nil {fmt.Println(err.Error())return err}
Found the example here - https://pkg.go.dev/sigs.k8s.io/controller-runtime/pkg/client
but it doesn't mention anything about all namespaces.
Could someone plz provide a way to figure this out.
NOTE:
This is custom resource. not default kind such as pod or deployment etc

使用List方法获取所有命名空间中所有资源的列表，然后循环遍历该列表，并使用Delete方法删除每个资源。
cr := &v1alpha1.CustomResource{}// 获取所有命名空间中您自定义资源的所有实例的列表listOpts := []client.ListOption{client.InNamespace(v1.NamespaceAll),}err := k8sClient.List(context.Background(), cr, listOpts...)if err != nil {return err}// 循环遍历列表并删除每个自定义资源的实例for _, item := range cr.Items {err = k8sClient.Delete(context.Background(), &item)if err != nil {return err}}
英文:
Use the List method to get a list of all resources in all namespaces and then loop through the list and delete each resource using the Delete method.

cr := &v1alpha1.CustomResource{}// Get a list of all instances of your custom resource in all namespaceslistOpts := []client.ListOption{client.InNamespace(v1.NamespaceAll),}err := k8sClient.List(context.Background(), cr, listOpts...)if err != nil {return err}// Loop through the list and delete each instance of your custom resourcefor _, item := range cr.Items {err = k8sClient.Delete(context.Background(), &item)if err != nil {return err}}
