Storage Class and PVCs

Set up Storage Classes and PVCs in Kubernetes

Step 1: Create an Amazon EFS

Refer to steps here

Step 2: Create Storage Class with EFS Parameter

Navigate to Kubernetes -> Storage -> Storage Class

Configure EFS parameter created at Step1 by clicking on EFS Parameter.

K8s Storage Class Page

Step 3: Create Persistent Volume (PVC) using Storage Class

Here, we are configuring Kubernetes to use Storage Class created in Step 2 above, to create a Persistent Volume with 10Gi of storage capacity and ReadWriteMany access mode.

K8s Storage Class (Persistent Volume Claim Tab)

if you use K8s and PVCs to autoscale your storage groups and run out of space, simply adding new storage volumes may not resolve the issue. Instead, you must increase the size of the existing PVCs to accommodate your storage needs.

For guidance on how to perform volume expansion in Kubernetes, refer to the following resources:

• Increasing Disk Size in a StatefulSet

• Expanding Persistent Volume Claims in Kubernetes

• Expanding Kubernetes Persistent Volumes on EKS

Step 4: Mount PVC to the POD Deployment

Configure below in Volumes to create your application deployment using this PVC.

Volumes field

# Deployment using PersistentVolumeClaim. 
- Name: <volumne name>
  Path: <mount path>
  Spec:
    PersistentVolumeClaim:
      claimName: <pvc name>
