Storage Classes
Introduction
A StorageClass provides a way for administrators to describe the “classes” of storage they offer. Different classes map to options such as reclaim policy and to allow or not allow volume expansion determined by the cluster administrators. Kubernetes itself is un-opinionated about what classes represent.
As the Cloud Platform is hosted on AWS, the Provisioner is always set to AWS Elastic Block Store (AWS EBS)
Storage Class Options
The Cloud Platform currently offers 2 storage classes for users:
| Name | Provisioner | Reclaim Policy | Allow Volume Expansion |
|---|---|---|---|
| gp2 | aws-ebs | Delete | false |
| gp2-expand | aws-ebs | Delete | true |
| gp3 | ebs.csi.aws | Delete | true |
| io1-expand | aws-ebs | Delete | true |
The default class is gp3
AWS EBS storage classes allows a number of different configuration points when creating each class. If you feel the above storage classes do not fit your requirements, please speak to the Cloud Platform team.
