Provision a PVC on the File Storage Service

The Oracle Cloud Infrastructure File Storage service provides a durable, scalable, distributed, enterprise-grade network file system.

Provision PVCs on the File Storage Service (FSS)

Provisioning PVCs on FSS consists of 3 steps:

1. Create an FSS instance and a mount target
2. Define and create a PV backed by FSS
3. Define and create a PVC provisioned by the PV

Configure the VCN and create an FSS

1. Choose your deployment scenario:
   1. Mount target and worker nodes in the same subnet
   2. Mount target and worker nodes in different subnets
   3. Mount target and instance use in-transit encryption
2. Implement security rules based on your deployment scenario
3. Create a FSS instance

Define and create a PV backed by FSS

1. Create a yaml file (fss-pv.yaml) to define the PV:

   apiVersion: v1
   kind: PersistentVolume
   metadata:
     name: fss-pv
   spec:
    capacity:
      storage: 50Gi
    volumeMode: Filesystem
    accessModes:
      - ReadWriteMany
    persistentVolumeReclaimPolicy: Retain
    csi:
      driver: fss.csi.oraclecloud.com
      volumeHandle: ocid1.filesystem.oc1.iad.aaaa______j2xw:10.0.0.6:/FileSystem1
   

2. In the yaml file, set:

   1. driver value to: fss.csi.oraclecloud.com
   2. volumeHandle value to: <FileSystemOCID>:<MountTargetIP>:<path>

   The <FileSystemOCID> is the OCID of the file system defined in the File Storage service, the <MountTargetIP> is the IP address assigned to the mount target and the <path> is the mount path to the file system relative to the mount target IP address, starting with a slash.

3. Create the PV from the manifest file:

   kubectl create -f fss-pv.yaml
   

Define and create a PVC provisioned by the PV

1. Create a manifest file (fss-pvc.yaml) to define the PVC:

   apiVersion: v1
   kind: PersistentVolumeClaim
   metadata:
     name: fss-pvc
   spec:
     accessModes:
       - ReadWriteMany
     storageClassName: ""
     resources:
       requests:
         storage: 50Gi
     volumeName: fss-pv
   

2. In the YAML file, set:

   1. storageClassName to ""
   2. volumeName to the name of the PV created earlier

3. Create the PVC from the manifest file:

   kubectl create -f fss-pvc.yaml
