NFS and SMB

This document provides suggestions for accessing NFS and SMB network shares from Docker containers.

Good Luck With That

Installing reliable NFS and/or SMB client services into containers is annoyingly difficult, and appears to not be a recommended approach. The more common pattern is to do the following:

  1. Install NFS/SMB client services on the Docker host machine,
  2. Mount the network share on the Docker host machine, either as part of the startup or just before running a container that requires it.
  3. Expose the mounted share to a container using the -v (or --volume) option to the docker run command.

Docker Volume Plugins

Docker volume plugins allow Docker to be extended so that containers can access different external storage systems.

One such plugin, called Netshare allows containers to mount NFS v3/4, AWS EFS or CIFS (SMB) shares. At the time of this article, this plugin has not been tested at Thinkbox Software.
