NFS当作动态存储参加pv报错

unexpected error getting claim reference: selfLink was empty, can‘t make reference

• 报错

E0209 04:58:34.682881       1 controller.go:1004] provision "mysql/www-nginx-0" class "managed-nfs-storage": unexpected error getting claim reference: selfLink was empty, can't make reference

• 原因： elfLink was empty 在k8s集群 v1.20之前都存在，在v1.20之后被删除，需要在/etc/kubernetes/manifests/kube-apiserver.yaml 添加参数
  增加 - --feature-gates=RemoveSelfLink=false

spec:
containers:
- command:
    - kube-apiserver
    - --feature-gates=RemoveSelfLink=false
