k8s持久化存储之NFS

首先在集群之外安装服务端

nfs-server

bashCopy
apt update
apt upgrade
apt install nfs-kernel-server

mkdir -p /srv/nfs/share #创建共享目录
chmod 777 /srv/nfs/share #分配权限
echo "/srv/nfs/share 192.168.100.0/24(rw,sync,no_root_squash,no_subtree_check)" >> /etc/exports
exportfs -rv //使配置生效

#验证挂载
showmount -e localhost
#Export list for localhost:
#/srv/nfs/share 192.168.100.0/22

nfs-client

所有节点安装nfs客户端!!⚠️

bashCopy
apt update
apt upgrade
apt-get install -y nfs-common
showmount -e 192.168.100.193
#Export list for 192.168.100.0:
#/srv/nfs/share 192.168.100.0/22

k8s 安装

驱动安装

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

bashCopy
curl -skSL https://raw.githubusercontent.com/kubernetes-csi/csi-driver-nfs/master/deploy/install-driver.sh | bash -s master --

StorageClass

参考https://github.com/kubernetes-csi/csi-driver-nfs/blob/master/deploy/storageclass.yaml 博主直接使用

bashCopy
