The Scaleway Block Volume Container Storage Interface (CSI) driver is an implementation of the CSI interface to provide a way to manage Scaleway Block Volumes through a container orchestration system, like Kubernetes.
WARNING: this project is under active development and should be considered alpha.
| Scaleway CSI Driver \ CSI Version | v1.2.0 |
|---|---|
| master branch | yes |
| v0.1.0 | yes |
Here is a list of functionality implemented by the Scaleway CSI driver.
Raw Block Volumes allows the block volume to be exposed directly to the container as a block device, instead of a mounted filesystem. To enable it, the volumeMode needs to be set to Block. For instance, here is a PVC in raw block volume mode:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: my-raw-pvc
spec:
volumeMode: Block
[...]Volume Snapshots allows the user to create a snapshot of a specific block volume.
The Scaleway CSI driver implements the NodeGetVolumeStats CSI method. It is used to gather statistics about the used block volumes. In Kubernetes, kubelet exposes these metrics.
This section is Kubernetes specific. Note that Scaleway CSI driver may work for older Kubernetes version than those announced. The CSI driver allows to use Persistent Volumes in Kubernetes.
| Scaleway CSI Driver \ Kubernetes Version | K8S v1.17 |
|---|---|
| master branch | yes |
| v0.1.0 | yes |
Some examples are available here.
These steps will cover how to install the Scaleway CSI driver in your Kubernetes cluster.
- A Kubernetes cluster running on Scaleway instances (v1.17+)
- Scaleway Organizaton ID, Access and Secret key
- Configure the Scalewy secrets.
Edit the secret file in order to set your own secrets. Once replaced, you can create the secret:
$ kubectl apply -f ./deploy/kubernetes/scaleway-secret.yaml- Deploy the Scaleway CSI driver and the needed sidecars.
It's recommended to deploy the latest tagged version, but you can also deploy the master version. Here we will deploy the latest version 0.1.0.
$ kubectl apply -f ./deploy/kubernetes/scaleway-csi-v0.1.0.yamlYou can now verify that the driver is running:
$ kubectl get pods -n kube-system
[...]
scaleway-csi-controller-76897b577d-b4dgw 5/5 Running 0 3m
scaleway-csi-node-hvkfw 3/3 Running 0 3m
scaleway-csi-node-jmrz2 3/3 Running 0 3m
[...]and you should see the scaleway-csi-controller and the scaleway-csi-node pods.
You can build the Scaleway CSI driver executable using the following commands:
make buildYou can build a local docker image named scaleway-csi for your current architecture using the following command:
make docker-buildIn order to run the tests:
make testIf you are looking for a way to contribute please read the contributing guide
