Ken, et al.,

I believe you can build your own and publish it to Dockerhub - unless their 
policies have changed.

It's been 4 years since I retired and worked with Docker containers, so I 
haven't touched Docker since as I no longer have access to my linux systems.
But I created the first "generic" SL6 container for Dockerhub and published it 
there myself.  It's a basic SL6.8 build, whereas all of the other SL6 containers 
on Dockerhub at the time were very specialized builds.  I believe Lynn Garren at 
Fermilab was using it as well.  I built mine for use on Cray supercomputer 
platforms to run ATLAS experiment jobs.  It's basically a clone I built of one 
of my interactive login nodes of my Tier3 cluster.

It might still be there at lnelson/test:v4.  Dunno how long they keep old 
containers.  But, of course, it's woefully out of date now and hasn't been 
updated with patches.

Seems the best course of action would be to build an SL6 system just the way you 
want it with all the legacy apps you need and then clone it with Docker and 
publish it to Dockerhub.  I think (but not sure) you can restrict access to it 
after publishing to Dockerhub.

There may be more apps that I am unaware of.  That's why I asked.  If you plan to remove the sl6 base image from docker, then I need to preserve a copy somehow or learn to build one from scratch using an archive sl6 repo, or maybe even preserve a full sl6 repo myself.
