[英]Does kubectl delete namespace command deletes associated storageclasses also?
I am new to Kube.netes, and have a question about it.我是 Kube.netes 的新手,对此有疑问。
When we create a statefulset, it gets associated with its PVC and the PVC will be associated a storageclass.当我们创建一个有状态集时,它会与其 PVC 相关联,而 PVC 将与一个存储类相关联。
So when we execute command "kubectl delete namespace", should it delete the storageclasses also?那么当我们执行命令“kubectl delete namespace”时,它是否也应该删除存储类?

Not All Objects are in a Namespace 并非所有对象都在命名空间中
Most Kubernetes resources (eg pods, services, replication controllers, and others) are in some namespaces. 大多数Kubernetes资源(例如pod,服务,复制控制器和其他资源)都位于某些命名空间中。 And low-level resources, such as nodes and persistentVolumes, are not in any namespace. 而且低级资源(例如节点和persistentVolumes)不在任何命名空间中。 Source. 资源。
The storage class is not a namespace object. 存储类不是名称空间对象。 Try to run $ kubectl get storageclass --all-namespaces
and you will notice that there is not even the indication of the namespace: 尝试运行$ kubectl get storageclass --all-namespaces
,您会注意到甚至没有名称空间的指示:
xxx@xxxxx.xx:~$ kubectl get storageclass --all-namespaces
NAMESPACE NAME PROVISIONER
slow kubernetes.io/gce-pd
standard (default) kubernetes.io/gce-pd
Therefore I have never paid attention, but I believe that if you delete a namespace nothing will happen to the Storage class objects. 因此,我从来没有关注过,但是我相信,如果删除命名空间,则Storage类对象将不会发生任何事情。
Update: 更新:
I created a namespace class "paolo" the following StorageClass: 我在以下StorageClass中创建了一个名称空间类“ paolo”:
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: slow
namespace: paolo
provisioner: kubernetes.io/gce-pd
parameters:
type: pd-standard
zones: us-central1-a, us-central1-b
I didn't received any error, I deleted the namespace paolo and as expected the StorageClass was still there 我没有收到任何错误,我删除了名称空间paolo,并且正如预期的那样,StorageClass仍然存在
