Preparing MongoDB Storage

About this task

Follow the steps below to create the EFS access point, Persistent Volume (PV), and Persistent Volume Claim (PVC) for MongoDB.

Procedure

  1. Create an EFS access point for MongoDB. The root directory for this access point will be /bitnami/mongodb: 
    EFS_AP_MONGODB=$(aws efs create-access-point \
  --file-system-id $EFS_FS_ID \
  --posix-user Uid=1000,Gid=1000 \
  --root-directory "Path=/bitnami/mongodb,CreationInfo={OwnerUid=1000,OwnerGid=1000,Permissions=777}" \
  --region $AWS_REGION \
  --query 'AccessPointId' \
  --output text)
  2. Create the Persistent Volume (PV) using the EFS driver and the access point you just created: 
    echo "
apiVersion: v1
kind: PersistentVolume
metadata:
  name: link-mongodb-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_MONGODB
" | kubectl apply -f -
  3. Create the Persistent Volume Claim (PVC) and bind it to the PV: 
    echo "
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: link-mongodb-pvc
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: efs-sc
  volumeName: link-mongodb-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-mongodb-pvc
    Example output:
    Name                    STATUS    VOLUME            CAPACITY   ACCESS MODES    STORAGECLASS    VOLUMEATTRIBUTESCLASS    AGE    
link-mongodb-pvc        Bound     link-mongodb-pv   5Gi        RWX             efs-sc          <unset>                  20s
