配置k8s nfs动态存储类

安装nfs（服务端）

关闭防火墙

systemctl stop firewalld
systemctl disable firewalld

yum install -y nfs-utils

设置开机启动并立即启动

systemctl enable rpcbind --now
systemctl enable nfs --now

创建共享目录并授予权限

mkdir -p /nfs/share/data
chmod 755 /nfs/share/data

设置共享目录

vim /etc/exports
/nfs/share/data/     *(rw,sync,no_root_squash,no_all_squash)
# 重启nfs
systemctl restart nfs
# 检查共享目录
showmount -e localhost

客户端

yum install -y nfs-utils

设置开机启动并立即启动

systemctl enable rpcbind --now

查看服务器共享目录

showmount -e 10.211.55.3

挂载目录

mkdir -p /nfs/share/data
mount -t nfs 10.211.55.3:/nfs/share/data /nfs/share/data

设置开机自动挂载

vim  /etc/fstab
10.211.55.3:/nfs/share/data    /nfs/share/data   nfs     defaults   0 0

安装NFS CSI 驱动程序

# 记得修改镜像（我以把修改后的上传到附件中）
git clone https://github.com/kubernetes-csi/csi-driver-nfs.git
cd csi-driver-nfs
./deploy/install-driver.sh v4.9.0 local

创建存储类并配置成默认存储类
创建配置文件：storageclass-nfs.yaml

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: nfs-csi
  annotations:
    storageclass.kubernetes.io/is-default-class: "true"
provisioner: nfs.csi.k8s.io
parameters:
  server: 10.211.55.3
  share: /nfs/share/data/
reclaimPolicy: Delete
volumeBindingMode: Immediate
mountOptions:
  - nfsvers=4.1

创建

kubectl apply -f storageclass-nfs.yaml

验证
创建配置文件：pvc-nfs-csi-dynamic.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-nfs-dynamic
  namespace: default
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1Gi
  storageClassName: nfs-csi

创建

kubectl apply -f pvc-nfs-csi-dynamic.yaml

查看pvc/pv

# pvc
kubectl get pvc
# pv
kubectl get pv
# 查看共享文件夹下pv
ls /nfs/share/data/

# 清理 pvc
kubectl delete -f pvc-nfs-csi-dynamic.yaml
