From having tried a few times on a mac, it's really hard to get started. The local provider is LXC-based so can only run on linux. I'd love it if it ran on docker or virtualbox.
It takes some steps towards resolving some of the issues in the article as well as a number of other headaches I've encountered when trying to bend docker to my will and build a development environment I can use every day for everything without having to mess around with basic plumbing.
I can post a show HN about it in the days ahead if there's any interest - it's not anywhere near where I want it to be (least of all in terms of code quality) but the amount of time I can devote to coding is about to drop from "near zero" to "really REALLY near zero" for a while, and it's very usable and handy so it might be worth just tossing it out there as-is and coming back to it at a later date.
