terraform-kubernetes-hcloud-csi-driver
A simple module to provision the Hetzner Container Storage Interface Driver within a Kubernetes cluster running on Hetzner Cloud. See the variables file for the available configuration options. Please note that this module requires Kubernetes 1.15 or newer.
Prerequisites
Requires cluster nodes be prior initialized by a cloud-controller-manager. You can use the terraform-kubernetes-hcloud-controller-manager module to initialize your cluster nodes.
Deploy Test Persistent Volume
Verify everything is working, create a persistent volume claim and a pod which uses that volume:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: csi-pvc
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 10Gi
storageClassName: hcloud-volumes
---
kind: Pod
apiVersion: v1
metadata:
name: my-csi-app
spec:
containers:
- name: my-frontend
image: busybox
volumeMounts:
- mountPath: "/data"
name: my-csi-volume
command: [ "sleep", "1000000" ]
volumes:
- name: my-csi-volume
persistentVolumeClaim:
claimName: csi-pvc
Once the pod is ready, exec a shell and check that your volume is mounted at /data.
kubectl exec -it my-csi-app -- /bin/sh
