# 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
- Static (per Node) StorageClasses
### …and what doesn't (yet)
- Volume snapshots
- Volume backups using [Borg Backup](https://www.borgbackup.org/)
- Dynamic (single) StorageClass (automatic node selection and assignment)
- Automatically moving volumes between nodes
## Getting started
### Prerequisites
- A running K8s cluster
- A BTRFS directory or filesystem at `/volumes`.
### Installation
First of all, **this is experimental software**. You're up on your own should you lose data.
#### Helm
`helm repo add btrfs-provisioner https://timoschwarzer.github.io/btrfs-provisioner`
#### Manual
Deploy the manifests in the `deploy` directory:
```shell
kubectl apply -f deploy/meta.yaml
kubectl apply -f deploy/controller.yaml
```
The BTRFS provisioner controller creates a StorageClass for each worker node on startup.
