# 1.部署nfsclass #

**Helm部署nfs-client-provisioner：** 预先配置好外部的NFS服务器。

[kubeadm@server1 nfsclass]$ ls
    class.yaml  deployment.yaml  pod.yaml  pvc.yaml  rbac.yaml
    
    [kubeadm@server1 nfsclass]$ kubectl delete -f .  // 删除之前的部署
    storageclass.storage.k8s.io "managed-nfs-storage" deleted
    deployment.apps "nfs-client-provisioner" deleted
    serviceaccount "nfs-client-provisioner" deleted
    clusterrole.rbac.authorization.k8s.io "nfs-client-provisioner-runner" deleted
    clusterrolebinding.rbac.authorization.k8s.io "run-nfs-client-provisioner" deleted
    role.rbac.authorization.k8s.io "leader-locking-nfs-client-provisioner" deleted
    rolebinding.rbac.authorization.k8s.io "leader-locking-nfs-client-provisioner" deleted
    Error from server (NotFound): error when deleting "pod.yaml": pods "test-pod" not found
    Error from server (NotFound): error when deleting "pvc.yaml": persistentvolumeclaims "test-claim" not found
    
    注意：在使用helm uninstall删除的时候，调用的是kubectl apiserver，通过config完成授权

[kubeadm@server2 .kube]$ ls
    cache  config  http-cache
    [kubeadm@server2 .kube]$ pwd
