Hi David,
what I did when testing sti-nodejs, was that I have build sti-base[1] 
from scratch for rhel7. You will end up with openshift/base-rhel7
build sti-nodejs afterwards you will have openshift/nodejs-010-rhel7 in 
you local images list. Now you are ready to build&run your nodejs 
application image with sti, like explained in usage[3].
