试验环境为 ubuntu 20.04
一、nfs 部署安装
- 安装 nfs
apt-get install nfs-kernel-server- 创建共享目录
mkdir nfs_data- 修改共享配置
root@master:~# vim /etc/exports/root/nfs_data *(rw,no_root_squash)- 重启 nfs
/etc/init.d/nfs-kernel-server restart- 查看共享目录
showmount -e二、安装 nfs provisioner
官方文档
- 创建 server account 用户
service_account.yaml
apiVersion:v1kind:ServiceAccountmetadata:name:nfs-provisioner- 启动 service account 并查看
kubectl apply -f service_account.yaml kubectl get sa- 创建 ServiceAccount
授权给 nfs 可以访问 k8s 内部一些功能
kubectl create clusterrolebinding nfs-provisioner-clusterrolebinding --clusterrole=cluster-admin --serviceaccount=default:nfs-provisioner- 创建 nfs deployment
k8s.gcr.io/sig-storage/nfs-subdir-external-provisioner:v4.0.0下载不下来可以考虑其他办法下载完成后传到节点上。使用ctr -n=k8s.io images import nfs-subdir-external-provisioner.tar.gz
nfs-deployment.yaml
