nfs-csi驱动部署

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

部署

1）克隆仓库

export https_proxy=http://frp1.freefrp.net:16324
git clone --depth 1 https://github.com/kubernetes-csi/csi-driver-nfs.git
cd csi-driver-nfs

version=v4.4.0
wget https://raw.githubusercontent.com/kubernetes-csi/csi-driver-nfs/${version}/deploy/example/nfs-provisioner/nfs-server.yaml
unset https_proxy

2）下载镜像替换脚本

wget https://files.cnblogs.com/files/blogs/731344/rep-docker-img.sh
sh rep-docker-img.sh

3）部署nfs-csi

注：默认源码里面把kubelet的数据目录写死成/var/lib/kubelet了，如果有改过kubelet数据目录，可以执行这个脚本更改

wget https://files.cnblogs.com/files/blogs/731344/rep-kbdata-dir.sh
sh rep-kubdata-dir.sh

./deploy/install-driver.sh ${version} local

4）部署nfs-server

方法1：直接使用k8s的pod当做nfs服务

kubectl apply -f nfs-server.yaml

方法2：使用物理机/虚拟机搭建nfs服务

mkdir -p /data/nfs
chown nobody:nobody /data/nfs
chmod 0777 /data/nfs

yum install -y nfs-utils
echo '/data/nfs 2.2.2.0/24(rw,sync,no_subtree_check)' >> /etc/exports
systemctl enable --now nfs-server.service
exportfs -av
showmount -e 127.0.0.1

5）创建存储类

方法1：pod方式运行nfs-server

kubectl apply -f - <<eof
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: nfs-csi
provisioner: nfs.csi.k8s.io
parameters:
  #nfs-server的svc域名，如果部署在非默认的ns，则需要修改
  server: nfs-server.default.svc.cluster.local
  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: Delete
volumeBindingMode: Immediate
mountOptions:
- nfsvers=4.1
eof

方法2：对应虚拟机搭建nfs-server

kubectl apply -f - <<EOF
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: nfs-csi
provisioner: nfs.csi.k8s.io
parameters:
  server: 2.2.2.45
  share: /data/nfs
reclaimPolicy: Retain
volumeBindingMode: Immediate
mountOptions:
- hard
- nfsvers=4.1
EOF

6）测试动态pvc申请

kubectl apply -f - <<EOF
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-nfs-dynamic
spec:
  storageClassName: nfs-csi
  accessModes: [ReadWriteOnce]
  resources:
    requests:
      storage: 100Mi
EOF

7）卸载/清理

kubectl delete pvc pvc-nfs-dynamic

#卸载驱动
./deploy/uninstall-driver.sh ${version} local
