k8s 1.22使用nfs存储类报错：unexpected error getting claim reference: selfLink was empty, can‘t make referenc_class "flink-log-nfs-storage": unexpected error ge

报错提示

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

原因定位

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

解决办法

vim /etc/kubernetes/manifests/kube-apiserver.yaml

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