Hi, good to know that, its great that you want to learn ES, elixir and ES is a very nice mix.
To answer your question, right now its just myself working on it since its not at stage where someone can use it right the way I didn’t bother to create a Gitter. I can definitely create one once it get has some tractions, or if there is people willing to contribute.
And yes, eventually I do want to make it agnostic to 3rd party services.
I am not too familiar with docker and how that work, lets chat further on Slack
