Intro

This is a Helm chart for the Fairwinds Gemini project. 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 for more information.

Installation

helm repo add fairwinds-stable https://charts.fairwinds.com/stable
helm install gemini fairwinds-stable/gemini --namespace gemini --create-namespace

Requirements

Your cluster must support the VolumeSnapshot API

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.
