实验准备

删除所有的pv和pvc：

[root@server1 helm]# kubectl delete pvc --all
......
[root@server1 helm]# kubectl get pv
No resources found in default namespace.
[root@server1 helm]# kubectl get pvc
No resources found in default namespace.

删除之前部署的nfs-client：

[root@server1 ~]# cd volumes/pv/nfsclass/
[root@server1 nfsclass]# ls
class.yaml  deployment.yaml  pod.yaml  pvc.yaml  rbac.yaml
[root@server1 nfsclass]# kubectl delete -f .
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

一、部署nfs-client

查找chart：

[root@server1 nfsclass]# helm search repo nfs
NAME                         	CHART VERSION	APP VERSION	DESCRIPTION                                       
stable/nfs-client-provisioner	1.2.8        	3.1.0      	nfs-client is an automatic provisioner that use...
stable/nfs-server-provisioner	1.0.0        	2.3.0      	nfs-server-provisioner is an out-of-tree dynami...

由于nfs服务端我们已经部署好了，因此只部署nfs-client即可。

拉取及解压：

[root@server1 helm]# helm pull stable/nfs-client-provisioner
[root@server1 helm]# ls
mychart  nfs-client-provisioner-1.2.8.tgz
[root@server1 helm]# tar xf nfs-client-provisioner-1.2.8.tgz 
......
[root@server1 helm]# cd nfs-client-provisioner/
[root@server1 nfs-client-provisioner]# ls
Chart.yaml  ci  OWNERS  README.md  templates  values.yaml

我们对版本文件不做更改，只更改变量文件：

[root@server1 nfs-client-provisioner]# vim values.yaml 

之后创建一个独立的namespace：

[root@server1 nfs-client-provisioner]# kubectl create namespace nfs-client-provisioner
namespace/nfs-client-provisioner created

安装chart（-n选项指定namespace）：

[root@server1 nfs-client-provisioner]# helm install nfs-client-provisioner . -n nfs-client-provisioner
NAME: nfs-client-provisioner
LAST DEPLOYED: Tue May 12 23:52:05 2020
NAMESPACE: nfs-client-provisioner
STATUS: deployed
REVISION: 1
TEST SUITE: None


查看：
[root@server1 nfs-client-provisioner]# helm list -n nfs-client-provisioner
NAME                  	NAMESPACE             	REVISION	UPDATED                                	STATUS  	CHART                       	APP VERSION
nfs-client-provisioner	nfs-client-provisioner	1       	2020-05-12 23:52:05.651390456 +0800 CST	deployed	nfs-client-provisioner-1.2.8	3.1.0      

查看pod状态：

[root@server1 nfs-client-provisioner]# kubectl -n nfs-client-provisioner get all
NAME                                          READY   STATUS    RESTARTS   AGE
pod/nfs-client-provisioner-65f7bdd89d-hthhc   1/1     Running   0          55s

NAME                                     READY   UP-TO-DATE   AVAILABLE   AGE
deployment.apps/nfs-client-provisioner   1/1     1            1           55s

NAME                                                DESIRED   CURRENT   READY   AGE
replicaset.apps/nfs-client-provisioner-65f7bdd89d   1         1         1       55s

部署成功。

查看创建的默认storageClass：

[root@server1 nfs-client-provisioner]# kubectl -n nfs-client-provisioner get sc
NAME                   PROVISIONER                            RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
nfs-client (default)   cluster.local/nfs-client-provisioner   Delete          Immediate           true                   48m

二、创建nfs pv

创建pvc：

[root@server1 helm]# vim pvc.yaml 
[root@server1 helm]# cat pvc.yaml 
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: pvc1
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 300Mi
      
[root@server1 helm]# kubectl create -f pvc.yaml 
persistentvolumeclaim/pvc1 created

查看pv和pvc已经发现部署成功：

[root@server1 helm]# kubectl get pvc
NAME   STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE
pvc1   Bound    pvc-00e836ef-43bb-4912-9b86-fe5131447eef   300Mi      RWO            nfs-client     6s
[root@server1 helm]# kubectl get pv
NAME                                       CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS   CLAIM          STORAGECLASS   REASON   AGE
pvc-00e836ef-43bb-4912-9b86-fe5131447eef   300Mi      RWO            Delete           Bound    default/pvc1   nfs-client              48s

实验后删除：

[root@server1 helm]# kubectl delete -f pvc.yaml 
persistentvolumeclaim "pvc1" deleted
[root@server1 helm]# kubectl get pv
No resources found in default namespace.
[root@server1 helm]# kubectl get pvc
No resources found in default namespace.
