Cinder CSI Driver
|
||||
===============
|
||||
|
||||
Cinder CSI driver allows you to provision volumes over an OpenStack deployment. The Kubernetes historic in-tree cloud provider is deprecated and will be removed in future versions.
|
||||
|
||||
To enable Cinder CSI driver, uncomment the `cinder_csi_enabled` option in `group_vars/all/openstack.yml` and set it to `true`.
|
||||
|
||||
To set the number of replicas for the Cinder CSI controller, you can change `cinder_csi_controller_replicas` option in `group_vars/all/openstack.yml`.
|
||||
|
||||
You need to source the OpenStack credentials you use to deploy your machines that will host Kubernetes: `source path/to/your/openstack-rc` or `. path/to/your/openstack-rc`.
|
||||
|
||||
Make sure the hostnames in your `inventory` file are identical to your instance names in OpenStack. Otherwise [cinder](https://docs.openstack.org/cinder/latest/) won't work as expected.
|
||||
|
||||
If you want to deploy the cinder provisioner used with Cinder CSI Driver, you should set `persistent_volumes_enabled` in `group_vars/k8s-cluster/k8s-cluster.yml` to `true`.
|
||||
|
||||
You can now run the kubespray playbook (cluster.yml) to deploy Kubernetes over OpenStack with Cinder CSI Driver enabled.
|
||||
|
||||
## Usage example ##
|
||||
|
||||
To check if Cinder CSI Driver works properly, see first that the cinder-csi pods are running:
|
||||
|
||||
```
|
||||
$ kubectl -n kube-system get pods | grep cinder
|
||||
csi-cinder-controllerplugin-7f8bf99785-cpb5v 5/5 Running 0 100m
|
||||
csi-cinder-nodeplugin-rm5x2 2/2 Running 0 100m
|
||||
```
|
||||
|
||||
Check the associated storage class (if you enabled persistent_volumes):
|
||||
|
||||
```
|
||||
$ kubectl get storageclass
|
||||
NAME PROVISIONER AGE
|
||||
cinder-csi cinder.csi.openstack.org 100m
|
||||
```
|
||||
|
||||
You can run a PVC and an Nginx Pod using this file `nginx.yaml`:
|
||||
|
||||
```
|
||||
---
|
||||
apiVersion: v1
|
||||
kind: PersistentVolumeClaim
|
||||
metadata:
|
||||
name: csi-pvc-cinderplugin
|
||||
spec:
|
||||
accessModes:
|
||||
- ReadWriteOnce
|
||||
resources:
|
||||
requests:
|
||||
storage: 1Gi
|
||||
storageClassName: cinder-csi
|
||||
|
||||
---
|
||||
apiVersion: v1
|
||||
kind: Pod
|
||||
metadata:
|
||||
name: nginx
|
||||
spec:
|
||||
containers:
|
||||
- image: nginx
|
||||
imagePullPolicy: IfNotPresent
|
||||
name: nginx
|
||||
ports:
|
||||
- containerPort: 80
|
||||
protocol: TCP
|
||||
volumeMounts:
|
||||
- mountPath: /var/lib/www/html
|
||||
name: csi-data-cinderplugin
|
||||
volumes:
|
||||
- name: csi-data-cinderplugin
|
||||
persistentVolumeClaim:
|
||||
claimName: csi-pvc-cinderplugin
|
||||
readOnly: false
|
||||
```
|
||||
|
||||
Apply this conf to your cluster: ```kubectl apply -f nginx.yml```
|
||||
|
||||
You should see the PVC provisioned and bound:
|
||||
```
|
||||
$ kubectl get pvc
|
||||
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
|
||||
csi-pvc-cinderplugin Bound pvc-f21ad0a1-5b7b-405e-a462-48da5cb76beb 1Gi RWO cinder-csi 8s
|
||||
```
|
||||
|
||||
And the volume mounted to the Nginx Pod (wait until the Pod is Running):
|
||||
|
||||
```
|
||||
kubectl exec -it nginx -- df -h | grep /var/lib/www/html
|
||||
/dev/vdb 976M 2.6M 958M 1% /var/lib/www/html
|
||||
```
|
||||
|
||||
## Compatibility with in-tree cloud provider ##
|
||||
It is not necessary to enable OpenStack as a cloud provider for Cinder CSI Driver to work.
|
||||
Though, you can run both the in-tree openstack cloud provider and the Cinder CSI Driver at the same time. The storage class provisioners associated to each one of them are differently named.
|
||||
|
||||
## Cinder v2 support ##
|
||||
For the moment, only Cinder v3 is supported by the CSI Driver.
|
||||
|
||||
## More info ##
|
||||
For further information about the Cinder CSI Driver, you can refer to this page: [Cloud Provider OpenStack](https://github.com/kubernetes/cloud-provider-openstack/blob/master/docs/using-cinder-csi-plugin.md).
