   Well, there is a case for automated testing. You might want to be able   
   to set up the whole OS and the database and then run automated tests.   
   with some branch of the application code. Running RAC inside Docker   
   might be handy in case you have everything else (app servers, proxies,   
   etc.) inside Docker.   
      
   You don't necessarily need a lot of resources and fast interconnects for   
   feature and regression testing.   
      
   And there are Oracle bugs which only affect RAC, so it would be   
   advisable to test applications on RAC before going to production.

   Well, Docker containers are pretty similar to Solaris containers (zones)   
   and the last time I set up Oracle in a Solaris zone it was because that   
   was the only Oracle approved way to limit the number of CPUs which   
   affected the licensing cost. :-)
