[root@nfs-server-01 ~]# ip a|grep inet|grep -v 127.0.0.1|grep -v inet6|awk '{print $2}'|tr -d "addr:"|awk -F '/' '{print $1}'
192.1.0.21
[root@nfs-server-01 ~]# cat /etc/exports
/data  *(rw,sync,no_root_squash)
[root@nfs-server-01 ~]# ps aux|grep nfs
root        960  0.0  0.0      0     0 ?        S<   13:40   0:00 [nfsd4_callbacks]

2. create nfs-client-provisioner

2.1 get yaml

helm inspect values stable/nfs-client-provisioner

2.2 modify the nfs server nfs path, name of nfs-client.yaml

replicaCount: 3
strategyType: Recreate
image:
  repository: quay.io/external_storage/nfs-client-provisioner
  tag: v3.1.0-k8s1.11
  pullPolicy: IfNotPresent
nfs:
  # here
  server: 192.1.0.21
  path: /data
  mountOptions:
storageClass:
  create: true
  defaultClass: false
  # here
  name: nfs-client
  allowVolumeExpansion: true
  reclaimPolicy: Delete
  archiveOnDelete: true
  accessModes: ReadWriteOnce
rbac:
  create: true
podSecurityPolicy:
  enabled: false
serviceAccount:
  create: true
  name:
resources: {}
nodeSelector: {}
tolerations: []
affinity: {}

2.3. install and uninstall

# install
kubectl create namespace elastic
helm install -n elastic nfs-client stable/nfs-client-provisioner -f nfs-client.yaml

# watch
helm list -n elastic

# upgrade
helm upgrade [RELEASE] [CHART] [flags]
helm upgrade -n elastic -f nfs-client.yaml nfs-client stable/nfs-client-provisioner

# uninstall
helm uninstall -n elastic nfs-client

3 create elasticsearch

3.1 get elasticsearch.yaml

helm repo add elastic https://helm.elastic.co
helm show values elastic/elasticsearch > values.yaml

3.2 add storageClassName of values.yaml

# The storageClassName must be consistent with nfs-client-provisioner's name
volumeClaimTemplate:
  storageClassName: "nfs-client"
  accessModes: ["ReadWriteOnce"]
  resources:
    requests:
      storage: 30Gi
