      Ruby 2.4 available as docker container is a base platform for 
      building and running various Ruby 2.4 applications and frameworks. 
      Ruby is the interpreted scripting language for quick and easy object-oriented programming. 
      It has many features to process text files and to do system management tasks (as in Perl). 
      It is simple, straight-forward, and extensible.
