Helm安装nfs-client-provisioner

一、准备工作

客户端安装 nfs-clinet

# RHEL 系节点
dnf install -y nfs-utils
# Debian/Ubuntu 节点
apt install -y nfs-common

验证

showmount -e nfs.qx.lab
mount -t nfs nfs.qx.lab:/data/nfs/k8s /mnt && umount /mnt   # 不报错就行

二、helm 安装

1. 添加仓库，更新仓库

helm repo add nfs-subdir-external-provisioner https://kubernetes-sigs.github.io/nfs-subdir-external-provisioner/
helm repo update nfs-subdir-external-provisioner

2. 安装

helm install nfs-provisioner \
  nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \
  --namespace nfs-system --create-namespace \
  --set nfs.server=nfs.qx.lab \
  --set nfs.path=/data/nfs/k8s \
  --set storageClass.name=nfs-client \
  --set storageClass.defaultClass=false \
  --set storageClass.archiveOnDelete=true

3. 验证

kubectl get pods -n nfs-system          # provisioner Running
kubectl get sc                          # 能看到 nfs-client

三、测一个PVC

1. 临时创建

vim 001-test-pvc.yaml 

apiVersion: v1
kind: PersistentVolumeClaim
metadata: { name: test-pvc }
spec:
  storageClassName: nfs-client
  accessModes: ["ReadWriteOnce"]
  resources: { requests: { storage: 1Gi } }

2. 创建资源

kubectl apply -f 001-tets-pvc.yaml 

2. 验证 pvc

kubectl get pvc test-pvc

3. 删除 pvc

kubectl delete pvc test-pvc
