### Service Parameters
@ -287,6 +291,37 @@ Paperless-ngx uses several directories:
All directories can be configured with separate PVCs and storage classes.
### Using Existing PVCs
The chart supports using existing PersistentVolumeClaims instead of creating new ones. This is useful for:
- Migrating from an existing Paperless-ngx deployment
- Using pre-provisioned storage with specific settings
- Sharing volumes across deployments
To use an existing PVC, specify the `existingClaim` parameter for the relevant volume:
```yaml
persistence:
data:
enabled: true
existingClaim: "my-existing-data-pvc"
media:
enabled: true
existingClaim: "my-existing-media-pvc"
export:
enabled: true
existingClaim: "" # Will create new PVC
consume:
enabled: true
existingClaim: "" # Will create new PVC
```
When `existingClaim` is specified:
- The chart will **NOT** create a new PVC
- The specified PVC must already exist in the same namespace
- `storageClass`, `size`, and `accessMode` parameters are ignored for that volume
- You can mix existing and new PVCs (some volumes with `existingClaim`, others without)
## Uninstalling the Chart
