Prepare a file system persistent volume

Prerequisite

1. Create an NFS Server.

2. Export the path.

3. In the example below, the yaml file uses the NFS server 10.10.10.10 and the exported path is: /my/nfs/volume/path.

Limitation

CTE for Kubernetes does not support mounting conventionally-protected PVCs and CTE-protected PVCs simultaneously. This could lead to unexpected behavior.

Create a Persistent Storage (PV) YAML file description

The following example explains how to create a persistent storage for CTE for Kubernetes to guard. Find more information on creating Persistent Volumes at:

• Persistent Volumes

Note

Replace the dummy entries for path and server with your own working NFS configuration.

nfs-pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
    name: nfs-test-pv
spec:
    capacity:
      storage: 1Gi
    accessModes:
    -  ReadWriteMany
    storageClassName: nfs
    persistentVolumeReclaimPolicy: Retain
    mountOptions:
        - hard
    nfs:
        path: /my/nfs/volume/path
        server: 10.10.10.10

Create a Persistent Storage Claim (PVC) YAML file description

nfs-claim.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
    name: nfs-test-claim
spec:
  storageClassName: nfs
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1Gi

Note

The PV name is not referenced in the PVC. This particular claim will claim any PV that matches the requirements.

Apply Persistent Storage YAML files

Type:

kubectl apply -f nfs-pv.yaml
kubectl apply -f nfs-claim.yaml
