Adding Storage

What is persistence

Persistence defines all forms of “storage” that can be added to a chart. This can be config text mounted to a file, ramdisks, or most frequently, actual data storage.

Requirements

For PVC storage to function correctly, it’s important to already have a storageClass defined and “Container Storage Interface” setup. Some platforms ship with this (SCALE, Harvester) others need you to set that up manually (TalosOS).

How to Setup

To setup persistence, add the following section to the values.yaml manually and adapt as needed:

persistence:
  config:
    enabled: true
    type: PVC
  mountPath: /mystorage

In some cases an ingress might already been partly defined. That means you should append the information as you need it, but not touch, for example, the mountPath.
