azk [0] is an open source development environment orchestrator for your local machine.
It is operated mainly via a CLI plus a manifest file (Azkfile.js) that describes architectures on a functional level (and the tool takes care of the rest).
You can quickly configure and start environments for new projects or for previously existing ones on top of which you'd like to iterate.
Everything runs on containers instead of VMs (currently, that means only Docker, but there are interesting additions on the way, such as hyper [1]).
It's really neat. Now, we've just added deployment features specifically for DigitalOcean at first.
You can check more azk tutorials on [2].
