build imagegw

Setting up the ImageGW

this can be done using docker-compose or, on a dedicated system, using the script imagegw/contrib/shifter-imagegw_build_env.

It can then be run using an init.d script similar to imagegw/contrib/shifter-imagegw_init_d

Pre-requisites

Make sure the system is using the same munge key as the cluster running shifter. Thenn Start & test munge

sudo /etc/init.d/munged start
munge -n | ssh imagegwnode unmunge
