Kubernetes NFS-Client Provisioner

nfs-client is an automatic provisioner that used your already configured NFS server, automatically creating Persistent Volumes.

Persistent volumes are provisioned as ${namespace}-${pvcName}-${pvName}

How to deploy nfs-client to your cluster.

To note, you must already have an NFS Server.

Editing:

Modify deploy.yaml and change the values to your own NFS server:

          env:
            - name: PROVISIONER_NAME
              value: fuseim.pri/ifs
            - name: NFS_SERVER
              value: 10.10.10.60
            - name: NFS_PATH
              value: /ifs/kubernetes
      volumes:
        - name: nfs-client-root
          nfs:
            server: 10.10.10.60
            path: /ifs/kubernetes

Modify deploy.yaml to match the same value indicated by PROVISIONER_NAME:

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: managed-nfs-storage
provisioner: fuseim.pri/ifs # or choose another name, must match deployment's env PROVISIONER_NAME'
parameters:
  archiveOnDelete: "false" # When set to "false" your PVs will not be archived by the provisioner upon deletion of the PVC.

Authorization

If your cluster has RBAC enabled, you must authorize the provisioner. If you are in a namespace/project other than "default" either edit auth.yaml.

Kubernetes:

$ kubectl create -f auth.yaml 
serviceaccount "nfs-client-provisioner" created
clusterrole "nfs-client-provisioner-runner" created
clusterrolebinding "run-nfs-client-provisioner" created

Finally, test your environment!

Now we'll test your NFS provisioner.

Deploy:

$ kubectl create -f test/test.yaml

Now check your NFS Server for the file SUCCESS.

kubectl delete -f test.yaml

Now check the folder has been deleted.

Deploying your own PersistentVolumeClaim

To deploy your own PVC, make sure that you have the correct storage-class as indicated by your deploy.yaml file.

For example:

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: test-claim
  annotations:
    volume.beta.kubernetes.io/storage-class: "managed-nfs-storage"
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1Mi
