For upcoming GitLab SR we need Ruby support.
We have minimal Ruby support in the form of Ruby component and rubygemsrecipe recipe to install gems. However a lot of top-level software/services in Ruby world is not released as gem and have to be installed / worked with via Bundler, and for this way we do not have an example.
Let's add such example in the form of extending helloworld SR to also say hello to the web in both Python and Ruby via simple Ruby program which is deployed via Bundler.
For this to happen, we need to make some preparatory changes first:
- move helloweb program(s) to own repository.
- modernize instance code and convert it to jinja2 to allow control structures.
- prepare instance infrastructure to support several helloweb program kinds.
and only then show how to do Ruby stuff via Bundler.
To me the effect of software/helloworld refactoring is good even without Ruby part, just to improve reference material about showing how to do.
@jerome, @kazuhiko, @rafael, @alain.takoudjou please have a look.
Thanks beforehand,
Kirill
P.S. this is also the basis for next merge request with Go support and helloweb-go.
