$ sudo docker run -i -t base /bin/bash
Step 2) Install node:

Plug the drive into the NFS Server and allow it to auto-mount (or manually mount it if necessary).
Install the NFS utils on the NFS Server:
- apt-get install nfs-kernel-server portmap
Update the /etc/exports file on the NFS Server to share the drive that is mounted at /media/backup:
- /media/backup 192.168.0.1/24(rw,sync,no_subtree_check,no_root_squash)
On the PC wanting to mount the drive /media/backup, create a local directory called /media/backup (it could be named something different):
