kubernetes - kubectl 命令修补 kubernetes 存储类中的特定属性

Question

我有以下 Kubernetes 存储类

Name:            encrypted-gp2
IsDefaultClass:  No
Annotations:     kubectl.kubernetes.io/last-applied-configuration={"allowVolumeExpansion":true,"apiVersion":"storage.k8s.io/v1","kind":"StorageClass","metadata":{"annotations":{},"name":"encrypted-gp2"},"parameters":{"encrypted":"true","fsType":"ext4","type":"gp2"},"provisioner":"kubernetes.io/aws-ebs","volumeBindingMode":"WaitForFirstConsumer"}

Provisioner:           kubernetes.io/aws-ebs
Parameters:            encrypted=true,fsType=ext4,type=gp2
AllowVolumeExpansion:  True
MountOptions:          <none>
ReclaimPolicy:         Delete
VolumeBindingMode:     WaitForFirstConsumer
Events:                <none>

现在我只想为 ReclaimPolicy 属性修补这个存储类，以便 ReclaimPolicy 切换到 Retain
在这种情况下，我正在寻找特定的补丁命令。

Answer 1

这将是简短而简单的🙂:

kubectl patch sc encrypted-gp2 -p '{"ReclaimPolicy":"Retain"}'

但是 StorageClass 是不可变的，因此您必须创建一个新的:

$ kubectl get sc encrypted-gp2 -o=yaml > sc.yaml

编辑 sc.yaml并更改回收政策🖥️。然后:

$ kubectl replace -f sc.yaml --force
