 h2. Install Docker
 
 Compute nodes must have Docker installed to run jobs inside containers.  This requires a relatively recent version of Linux (at least upstream version 3.10, or a distribution version with the appropriate patches backported).  Follow the "Docker Engine installation documentation":https://docs.docker.com/ for your distribution.
