# CSI Drivers
3+
4+
These drivers are provided purely for illustrative purposes, and should not be used for production workloads.
5+
6+
## Other sample drivers
7+
Please read [Drivers](https://kubernetes-csi.github.io/docs/Drivers.html) for more information
8+
9+
## Adding new sample drivers
10+
Please, DO NOT submit PRs to add new drivers here unless they are just examples. Real CSI drivers are to be housed on their own repo separate from this one. You are then welcomed to send a PR to https://github.com/kubernetes-csi/docs to add the [Driver](https://github.com/kubernetes-csi/docs/wiki/Drivers) page.

# CSI CFS Driver for K8S
2+
3+
## Kubernetes
4+
### Requirements
5+
6+
The folllowing feature gates and runtime config have to be enabled to deploy the driver
7+
8+
```
9+
FEATURE_GATES=CSIPersistentVolume=true,MountPropagation=true
10+
RUNTIME_CONFIG="storage.k8s.io/v1alpha1=true"
11+
```
12+
13+
Mountprogpation requries support for privileged containers. So, make sure privileged containers are enabled in the cluster.
14+
15+
### Get csi sidecar images
16+
17+
```docker pull quay.io/k8scsi/csi-attacher:v0.2.0```
18+
```docker pull quay.io/k8scsi/driver-registrar:v0.2.0```
19+
```docker pull quay.io/k8scsi/csi-provisioner:v0.2.0```
20+
21+
### Build cfscsi driver image
22+
23+
```docker build -t cfscsi:v1 deploy/.```
24+
25+
### Create configmap for csi driver
26+
27+
```kubectl create configmap kubecfg --from-file=deploy/kubernetes/kubecfg```
28+
29+
### Deploy cfs csi driver
30+
31+
```kubectl create -f deploy/kubernetes/cfs.yaml```
32+
33+
### Pre Volume: you must know volumeName first, example Nginx application
34+
35+
Please update the cfs Master Hosts & volumeName information in nginx-pre.yaml file.
36+
37+
```docker pull nginx```
38+
```kubectl create -f deploy/examples/nginx-pre.yaml```
39+
40+
### Dynamic volume: Example Nginx application
41+
42+
```docker pull nginx```
43+
```kubectl create -f deploy/examples/cfs-pvc.yaml```
44+
```kubectl create -f deploy/examples/cfs-pv.yaml```
45+
```kubectl create -f deploy/examples/nginx-dynamic.yaml```
