nginx的静态文件目录，映射到nfs的 pvc目录。
报错处理：
问题：在k8s 1.21.0版本使用NFS作为StorageClass，实现PV动态供给。但PVC一直是pending状态，Pod也无法运行
错误： Normal ExternalProvisioning 13s (x24 over 5m43s) persistentvolume-controller waiting for a volume to be created,
either by external provisioner "cluster.local/nfs-clife-pr-nfs-client-provisioner" or manually created by system administrator
原因：selfLink was empty 在k8s集群 v1.20之前都存在，在v1.20之后被删除
解决：需要在/etc/kubernetes/manifests/kube-apiserver.yaml 添加参数
[root@k8s-matser01 nfs.rbac]# cat /etc/kubernetes/manifests/kube-apiserver.yaml
apiVersion: v1
···
- --tls-private-key-file=/etc/kubernetes/pki/apiserver.key
- --feature-gates=RemoveSelfLink=false # 添加这个配置
然后再次查看deploy，pod，pvc，都会部署成功
kubectl get deploy,pod,pvc,sc,pv
