在K8S中使用NFS_resource mapping not found for name: "nfs-client-p

PS:

因为 原来是1.20版本默认禁止使用selfLink。 所以后续版本需要在kube-apiserver.yaml后面增加  - --feature-gates=RemoveSelfLink=false

最好解决方案: https://blog.csdn.net/joker_zhou/article/details/125478979

基本流程简单: 

1. 首先在客户端按照nfs 服务..这个网上一堆不介绍了,

2. 创建一个命名空间 (kubectl create namespace xxxx)

3. 创建rbac  (rbac.yaml)

4. 创建nfs的provisioner (deployment.yaml)

5. 创建StorageClass (storageClass.yaml)

6. 在PVC使用storageClass即可 (pvc.yaml)
