进入github下载相应版本
https://github.com/helm/helm
下载后解压直接使用，可放至/usr/bin目录下，增加执行权限

[root@myapp ~]# helm version

helm常用操作
查看chart仓库：helm repo list
添加chart仓库:helm repo add bitnami https://charts.bitnami.com/bitnami
在线查看服务：helm search repo bitnami/redis
在线部署redis：helm install redis1 bitnami/redis
查看已安装的服务：helm list
从仓库拉服务到本地：helm pull repo bitnami/redis
增加NFS存储类，以方便动态扩展PV
1.rbac.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: nfs-client-provisioner
  namespace: default        #根据实际环境设定namespace,下面类同
---
kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: nfs-client-provisioner-runner
rules:
  - apiGroups: [""]
    resources: ["persistentvolumes"]
    verbs: ["get", "list", "watch", "create", "delete"]
  - apiGroups: [""]
    resources: ["persistentvolumeclaims"]
    verbs: ["get", "list", "watch", "update"]
  - apiGroups: ["storage.k8s.io"]
    resources: ["storageclasses"]
    verbs: ["get", "list", "watch"]
  - apiGroups: [""]
    resources: ["events"]
    verbs: ["create", "update", "patch"]
---
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: run-nfs-client-provisioner
subjects:
  - kind: ServiceAccount
    name: nfs-client-provisioner
    namespace: default
roleRef:
  kind: ClusterRole
  name: nfs-client-provisioner-runner
  apiGroup: rbac.authorization.k8s.io
---
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: leader-locking-nfs-client-provisioner
  namespace: default
rules:
  - apiGroups: [""]
    resources: ["endpoints"]
    verbs: ["get", "list", "watch", "create", "update", "patch"]
---
kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: leader-locking-nfs-client-provisioner
subjects:
  - kind: ServiceAccount
    name: nfs-client-provisioner
    namespace: default
roleRef:
  kind: Role
  name: leader-locking-nfs-client-provisioner
  apiGroup: rbac.authorization.k8s.io

2.创建NFS资源的StorageClass，nfs-StorageClass.yaml

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: managed-nfs-storage
provisioner: qgg-nfs-storage #这里的名称要和provisioner配置文件中的环境变量PROVISIONER_NAME保持一致parameters:  archiveOnDelete: "false"

3.创建NFS provisioner，nfs-provisioner.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nfs-client-provisioner
  labels:
    app: nfs-client-provisioner
  namespace: default  #与RBAC文件中的namespace保持一致
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nfs-client-provisioner
  strategy:
    type: Recreate
  selector:
    matchLabels:
      app: nfs-client-provisioner
  template:
    metadata:
      labels:
        app: nfs-client-provisioner
    spec:
      serviceAccountName: nfs-client-provisioner
      containers:
        - name: nfs-client-provisioner
          image: quay.io/external_storage/nfs-client-provisioner:latest
          volumeMounts:
            - name: nfs-client-root
              mountPath: /persistentvolumes
          env:
            - name: PROVISIONER_NAME
              value: qgg-nfs-storage  #provisioner名称,请确保该名称与 nfs-StorageClass.yaml文件中的provisioner名称保持一致
            - name: NFS_SERVER
              value: 172.16.20.58   #NFS Server IP地址
            - name: NFS_PATH  
              value: /data/volumes    #NFS挂载卷
      volumes:
        - name: nfs-client-root
          nfs:
            server: 172.16.20.58  #NFS Server IP地址
            path: /data/volumes     #NFS 挂载卷

依次创建yaml
kubectl create -f rbac.yaml
kubectl create -f nfs-storage.yaml
kubectl create -f nfs-provisioner.yaml
查看存储类
[root@harbor opt]# kubectl get sc
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
managed-nfs-storage qgg-nfs-storage Delete Immediate false 145m
修改拉下来的redis中的values.yaml，如下部分：指定存储类，关闭主从模式

##
    storageClass: "managed-nfs-storage"
    accessModes:
    - ReadWriteOnce
    size: 8Gi
## Cluster settings
cluster:
  enabled: false
  slaveCount: 2

部署redis

[root@harbor opt]#  helm install -name redis-1 -n default -f values.yaml stable/redis
** Please be patient while the chart is being deployed **
Redis can be accessed via port 6379 on the following DNS name from within your cluster:
redis-1-master.default.svc.cluster.local
To get your password run:
    export REDIS_PASSWORD=$(kubectl get secret --namespace default redis-1 -o jsonpath="{.data.redis-password}" | base64 --decode)
To connect to your Redis server:
1. Run a Redis pod that you can use as a client:
   kubectl run --namespace default redis-1-client --rm --tty -i --restart='Never' \
    --env REDIS_PASSWORD=$REDIS_PASSWORD \
   --image docker.io/bitnami/redis:5.0.7-debian-10-r32 -- bash
2. Connect using the Redis CLI:
   redis-cli -h redis-1-master -a $REDIS_PASSWORD
To connect to your database from outside the cluster execute the following commands:
    kubectl port-forward --namespace default svc/redis-1-master 6379:6379 &
    redis-cli -h 127.0.0.1 -p 6379 -a $REDIS_PASSWORD

查看部署

[root@harbor opt]# kubectl get pods
NAME                                      READY   STATUS    RESTARTS   AGE
nfs-client-provisioner-556f974d45-j5lqp   2/2     Running   1          46m
redis-1-client                            2/2     Running   0          31m
redis-1-master-0                          2/2     Running   0          35m

进入客户端测试

I have no name!@redis-1-client:/$ redis-cli -h redis-1-master -a $REDIS_PASSWORD
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
redis-1-master:6379> set joyname chen
OK
redis-1-master:6379> get joyname
"chen"
