k8s 1.23 nfs动态存储nfs-subdir4.0.18

参考 https://blog.csdn.net/m0_51510236/article/details/132641343

nfs服务器：192.168.18.12

master：192.168.18.11

nfs动态存储只能应用在一个namespace，其他namespace可以自定义pv

1、在nfs服务器安装nfs

yum install nfs-utils -y

vim /etc/exports
/data/nfs/data1G *(rw,no_root_squash,no_all_squash,sync)
/data/nfs/data2G *(rw,no_root_squash,no_all_squash,sync)
/data/nfs/data3G *(rw,no_root_squash,no_all_squash,sync)
/data/nfs/data4G *(rw,no_root_squash,no_all_squash,sync)

systemctl start nfs && systemctl enable nfs
exportfs -rv

在别的服务器验证nfs

以下步骤在master操作

2、下载nfs-subdir源码包，github地址 https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner/releases

wget https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner/archive/refs/tags/nfs-subdir-external-provisioner-4.0.18.tar.gz

3、解压

tar -zxvf nfs-subdir-external-provisioner-4.0.18.tar.gz

4、需要修改的就是 deployment.yaml ，修改镜像仓库地址为 registry.cn-shenzhen.aliyuncs.com/xiaohh-docker/nfs-subdir-external-provisioner:v4.0.2

cd nfs-subdir-external-provisioner-nfs-subdir-external-provisioner-4.0.18
vim deploy/deployment.yaml

5、修改一下deployment.yaml的nfs服务器地址和nfs服务器内共享的目录：

6、安装动态供给，直接执行 kubectl apply -k . 安装。可以看到生成了nfs-client的pod和storageclass，因为源码目录里的class.yml定义了storageclass，deployment.yaml定义了pod。

7、可以执行下面这个行命令查看是否部署完成：

8、编写yaml验证nfs动态存储

vim  pod-exam.yaml
