## Intro
This is a Helm chart for the Fairwinds
[Gemini project ](https://github.com/FairwindsOps/gemini ).
It provides a Kubernetes CRD and operator for managing `VolumeSnapshots` , allowing you
to back up your `PersistentVolumes` on a regular schedule, retire old backups, and restore
backups with minimal downtime.
See the [Gemini README ](https://github.com/FairwindsOps/gemini ) for more information.
## Installation
```bash
helm repo add fairwinds-stable https://charts.fairwinds.com/stable
2023-04-12 11:14:31 +00:00
helm install gemini fairwinds-stable/gemini --namespace gemini --create-namespace
2021-04-19 10:46:42 +00:00
```
## Requirements
Your cluster must support the [VolumeSnapshot API ](https://kubernetes.io/docs/concepts/storage/volume-snapshots/ )
2023-04-12 11:14:31 +00:00
## Upgrading to V2
Version 2.0 of Gemini updates the CRD from `v1beta1` to `v1` . There are no substantial
changes, but `v1` adds better support for PersistentVolumeClaims on Kubernetes 1.25.
If you want to keep the v1beta1 CRD available, you can run:
```
kubectl apply -f https://raw.githubusercontent.com/FairwindsOps/gemini/main/pkg/types/snapshotgroup/v1beta1/crd-with-beta1.yaml
```
before upgrading, and add `--skip-crds` when running `helm install` .
