K8S部署csi 实现动态PV/PVC

k8s创建nfs

https://github.com/kubernetes-csi/csi-driver-nfs/blob/master/deploy/example/nfs-provisioner/README.md

 kubectl create ns nfs
 kubectl create -f <(curl -s https://raw.githubusercontent.com/kubernetes-csi/csi-driver-nfs/master/deploy/example/nfs-provisioner/nfs-server.yaml | sed 's/namespace: default/namespace: nfs/')

k8s创建install-csi-driver-v4.8.0

https://github.com/kubernetes-csi/csi-driver-nfs/blob/master/docs/install-csi-driver-v4.8.0.md

k8s创建 StorageClass

https://github.com/kubernetes-csi/csi-driver-nfs/blob/master/deploy/example/storageclass-nfs.yaml

 root@k8s-master01:~# vim nfs-csi.yaml
 ---
 apiVersion: storage.k8s.io/v1
 kind: StorageClass
 metadata:
   name: nfs-csi
 provisioner: nfs.csi.k8s.io
 parameters:
   server: nfs-server.nfs.svc.cluster.local  # nfs 名称空间下的 nfs服务
   share: /
   # csi.storage.k8s.io/provisioner-secret is only needed for providing mountOptions in DeleteVolume
   # csi.storage.k8s.io/provisioner-secret-name: "mount-options"
   # csi.storage.k8s.io/provisioner-secret-namespace: "default"
 reclaimPolicy: Retain #PV的删除策略，默认为delete，删除PV后立即删除NFS server的数据
 volumeBindingMode: Immediate
 allowVolumeExpansion: true
 mountOptions:
   - nfsvers=4.1
   
 root@k8s-master01:~# kubectl apply -f nfs-csi.yaml 
 root@k8s-master01:~# kubectl get sc

 nfs-csi   nfs.csi.k8s.io   Delete          Immediate           true                   29s

k8s给予StorageClass测试动态pv

https://github.com/kubernetes-csi/csi-driver-nfs/blob/master/deploy/example/pvc-nfs-csi-dynamic.yaml

 root@k8s-master01:~# vim pvc-nfs-csi-dynamic.yaml
