# Example of NFS volume
See [nfs-web-pod.yaml](nfs-web-pod.yaml) for a quick example, how to use NFS volume
in a pod.
## Complete setup
The example below shows how to export a NFS share from a pod and import it
into another one.
### NFS server part
Define [NFS server pod](nfs-server-pod.yaml) and
[NFS service](nfs-server-service.yaml):
$ kubectl create -f nfs-server-pod.yaml
$ kubectl create -f nfs-server-service.yaml
The server exports `/mnt/data` directory as `/` (fsid=0). The directory contains
dummy `index.html`. Wait until the pod is running!
### NFS client
[WEB server pod](nfs-web-pod.yaml) uses the NFS share exported above as a NFS
volume and runs simple web server on it. The pod assumes your DNS is configured
and the NFS service is reachable as `nfs-server.default.kube.local`. Edit the
yaml file to supply another name or directly its IP address (use
`kubectl get services` to get it).
Define the pod:
$ kubectl create -f nfs-web-pod.yaml
Now the pod serves `index.html` from the NFS server:
$ curl http://<the container IP address>/
Hello World!
