btrfs-provisioner for Kubernetes

This is a (work in progress) volume provisioner for Kubernetes leveraging the BTRFS filesystem to create volumes, enforce storage quotas, create snapshots and make backups.

What works…

• Volume provisioning
• Volume deletion
• Enforcing storage quotas

…and what doesn't (yet)

• Volume snapshots
• Volume backups using Borg Backup

Getting started

Prerequisites

• A running K8s cluster
• A BTRFS directory or filesystem at /volumes.

Installation

There are only plain Kubernetes manifests yet. A Helm chart should come soon when the provisioner reaches a stable state.

To deploy and test the BTRFS provisioner in your cluster, deploy the manifests in the deploy directory:

kubectl apply -f deploy/meta.yaml
kubectl apply -f deploy/controller.yaml
