Preparing Redis Storage

About this task

Complete the following steps to configure storage for Redis.

For Redis, use /bitnami/redis as the root directory for the EFS access point.

Procedure

  1. Create the EFS access point. 
    EFS_AP_REDIS=$(aws efs create-access-point \
  --file-system-id $EFS_FS_ID \
  --posix-user Uid=1000,Gid=1000 \
  --root-directory "Path=/bitnami/redis,CreationInfo={OwnerUid=1000,OwnerGid=1000,Permissions=777}" \
  --region $AWS_REGION \
  --query 'AccessPointId' \
  --output text)
  2. Create the Persistent Volume (PV) and link it to the EFS access point. 
    echo "
apiVersion: v1
kind: PersistentVolume
metadata:
  name: link-redis-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_REDIS
" | kubectl apply -f -
  3. Create the Persistent Volume Claim (PVC) and bind it to the PV. 
    echo "
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: link-redis-pvc
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: efs-sc
  volumeName: link-redis-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-redis-pvc
    Example output:
    NAME            STATUS    VOLUME            CAPACITY   ACCESS MODES    STORAGECLASS    VOLUMEATTRIBUTESCLASS    AGE    
link-redis-pvc  Bound     link-redis-pv      5Gi       RWX             efs-sc          <unset>                  15s
