修改apiserver的配置

二进制安装和kubeadm安装的apiserver配置文件路径不同，根据实际情况修改

[root@k8s-master ~]# cat /opt/kubernetes/cfg/kube-apiserver.conf
...
--proxy-client-key-file=/opt/kubernetes/ssl/server-key.pem \
--feature-gates=RemoveSelfLink=false \ #添加这个配置
--requestheader-allowed-names=kubernetes \
...

# 重启apiserver
[root@k8s-master ~]# systemctl restart kube-apiserver.service 

查看pvc状态

PVC正常绑定

[root@k8s-master ~]# kubectl get pvc
NAME                     STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS          AGE
