NFS安装制备器Provisioner

NFS subdir 外部驱动

https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner

第一、添加包仓库地址

helm repo add nfs-subdir-external-provisioner https://kubernetes-sigs.github.io/nfs-subdir-external-provisioner/

第二、先下载，修改包中的value.yaml，原因是image中的地址无法访问，另外修改为默认StorageClass存储

如果设置为默认的StorageClass存储，就可以在pvc中不用指定storageClassName,否则需要指定
helm pull nfs-subdir-external-provisioner/nfs-subdir-external-provisioner

replicaCount: 1
strategyType: Recreate

image:
  repository: registry.cn-hangzhou.aliyuncs.com/lfy_k8s_images/nfs-subdir-external-provisioner
  tag: v4.0.2
  pullPolicy: IfNotPresent
imagePullSecrets: []

nfs:
  server:
  path: /nfs-storage
  mountOptions:
  volumeName: nfs-subdir-external-provisioner-root
  # Reclaim policy for the main nfs volume
  reclaimPolicy: Retain

# For creating the StorageClass automatically:
storageClass:
  create: true

  # Set a provisioner name. If unset, a name will be generated.
  # provisionerName:

  # Set StorageClass as the default StorageClass
  # Ignored if storageClass.create is false
  defaultClass: true

  # Set a StorageClass name
  # Ignored if storageClass.create is false
  name: nfs-storage

  # Allow volume to be expanded dynamically
  allowVolumeExpansion: true

  # Method used to reclaim an obsoleted volume
  reclaimPolicy: Delete

  # When set to false your PVs will not be archived by the provisioner upon deletion of the PVC.
  archiveOnDelete: true

  # If it exists and has 'delete' value, delete the directory. If it exists and has 'retain' value, save the directory.
  # Overrides archiveOnDelete.
  # Ignored if value not set.
  onDelete:

  # Specifies a template for creating a directory path via PVC metadata's such as labels, annotations, name or namespace.
  # Ignored if value not set.
  pathPattern:

  # Set access mode - ReadWriteOnce, ReadOnlyMany or ReadWriteMany
  accessModes: ReadWriteOnce

  # Set volume bindinng mode - Immediate or WaitForFirstConsumer
  volumeBindingMode: Immediate

  # Storage class annotations
  annotations: {}

leaderElection:
  # When set to false leader election will be disabled
  enabled: true

## For RBAC support:
rbac:
  # Specifies whether RBAC resources should be created
  create: true

# If true, create & use Pod Security Policy resources
# https://kubernetes.io/docs/concepts/policy/pod-security-policy/
podSecurityPolicy:
  enabled: false

# Deployment pod annotations
podAnnotations: {}

## Set pod priorityClassName
# priorityClassName: ""

podSecurityContext: {}

securityContext: {}

serviceAccount:
  # Specifies whether a ServiceAccount should be created
  create: true

  # Annotations to add to the service account
  annotations: {}

  # The name of the ServiceAccount to use.
  # If not set and create is true, a name is generated using the fullname template
  name:

resources: {}
  # limits:
  #  cpu: 100m
  #  memory: 128Mi
  # requests:
  #  cpu: 100m
  #  memory: 128Mi

nodeSelector: {}

tolerations: []

affinity: {}

# Additional labels for any resource created
labels: {}

第三、安装

helm install nfs-subdir-external-provisioner /usr/local/resourece_yaml/nfs-subdir-external-provisioner\
    --set nfs.server=192.168.48.200 \
    --set nfs.path=/root/my_storage_class/data/nfs

第四、查看

kubectl get storageclass 或kubectl get sc

第五、可以创建一个pvc，查看是否直接可以动态的分配pv

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: myclaim
spec:
  accessModes:
    - ReadWriteOnce
  volumeMode: Filesystem
  resources:
    requests:
      storage: 100M
