安装NFS高可用集群

安装 nfs-client-provisioner

  1. curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3
  3. chmod 700 get_helm.sh
  5. ./get_helm.sh
  7. helm repo add azure http://mirror.azure.cn/kubernetes/charts/
  9. helm install nfs-storage azure/nfs-client-provisioner --set nfs.server="172.12.17.200" --set nfs.path=/fs/nsf-data --set storageClass.name=nfs-hw

创建PVC

kubectl apply -f nfs-pvc.yaml

  1. apiVersion: v1
  2. kind: PersistentVolumeClaim
  3. metadata:
  4.   name: nfs-pvc-test
  5. spec:
  6.   storageClassName: "nfs-hw"
  7.   accessModes:
  8.     - ReadWriteMany
  9.   resources:
  10.     requests:
  11.       storage: 10Gi

测试

kubectl apply -f nfs-test.yaml

  1. apiVersion: batch/v1
  2. kind: Job
  3. metadata:
  4.   name: nfsjob
  5. spec:
  6.   template:
  7.     spec:
  8.       containers:
  9.       - name: bbox1
  10.         image: busybox
  11.         args:
  12.         - /bin/sh
  13.         - -c
  14.         - echo "1231231231" > /nfs-data/hello
  15.         volumeMounts:
  16.         - mountPath: "/nfs-data"
  17.           name: nfsdata
  18.       restartPolicy: Never
  19.       volumes:
  20.       - name: nfsdata
  21.         persistentVolumeClaim:
  22.           claimName: nfs-pvc-test

end

  • 接下来去看看 NFS 服务器上是否有对应文件文件

K8S 集群是 v1.20+，在 nfs provisioner 创建 pvc 时，nfs provisioner 会报错
