Preparing the data Storage

About this task

The lnk-server, lnk-rest, and lnk-executor deployments share the same data storage.

Each of these deployments mounts the shared volume at the /data path, so that they all access the same content.

Complete the following steps to create the EFS access point, Persistent Volume (PV), and Persistent Volume Claim (PVC).

Procedure

  1. Create the EFS access point for the data volume. 
    EFS_AP_DATA=$(aws efs create-access-point \
  --file-system-id $EFS_FS_ID \
  --posix-user Uid=1000,Gid=1000 \
  --root-directory "Path=/data,CreationInfo={OwnerUid=1000,OwnerGid=1000,Permissions=777}" \
  --region $AWS_REGION \
  --query 'AccessPointId' \
  --output text)
  2. Create the Persistent Volume (PV). 
    echo "
apiVersion: v1
kind: PersistentVolume
metadata:
  name: link-data-pv
spec:
  capacity:
    storage: 5Gi
  volumeMode: Filesystem
  accessModes:
    - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: efs-sc
  csi:
    driver: efs.csi.aws.com
    volumeHandle: $EFS_FS_ID::$EFS_AP_DATA
" | kubectl apply -f -
  3. Create the Persistent Volume Claim (PVC) and bind it to the PV. 
    echo "
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: link-data-pvc
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: efs-sc
  volumeName: link-data-pv
  resources:
    requests:
      storage: 5Gi
" | kubectl apply -f -
  4. Verify that the PVC was created and successfully bound to the PV. 
    kubectl get pvc link-data-pvc
    Example output:
