Your success with this strategy correlates more strongly with ‘Go’ than ‘100 services’ so it’s more anecdotal than generally-acceptable that you can run 100 services locally without issues. Of course you can. Buying the biggest MacBook available as a baseline criteria for being able to run a stack locally with Docker Compose does not exactly inspire confidence. At my last company we switched our dev environment from Docker Compose to Nix on those same MacBooks and CPU usage when from 300% to <10% overnight.

  Have any details on how you've implemented Nix? For my personal projects I use nix without docker and the results are great. However I was always fearful that nix alone wouldn't quite scale as well as nix + docker for complicated environments. I've used the FROM SCRATCH strat with nix: https://mitchellh.com/writing/nix-with-dockerfiles https://mitchellh.com/writing/nix-with-dockerfiles Is that how you implemented it?

  Buying the biggest Mac’s also lets developers run an electron app or three (Slack, IDE, Spotify, browser, etc) while running the docker-compose stack.

    You're right. My coworkers remarked that they could run Slack and do screensharing while running the apps locally when we removed docker-compose.

  That's a huge win -- has your team written about or spoke on this anywhere?
  - JasonSage 2y ago
    No but I'd be happy to (I maintained the docker-compose stack, our CLI, and did the transition to Nix).
    - adamdecaf 2y ago
      I’d like to learn more about switching compose to nix. We will hit a wall with compose at some point.

      I'm curious about the # of svc's / stack / company / team size -- if you have your own blog -- would love to read it when you publish could be a cool lightning talk (or part of something longer) maybe it's a good piece for https://nixinthewild.com/ https://nixinthewild.com/ ? I'm @capileigh on twitter and hachyderm.io if you wanna reach out separately -- here is good tho too

        Hey, I plan to reach out when I get some time :) I can see there’s interest in the topic.

        sounds good! it's a cool anecdote :)

      Hi Jason! Like many others here I'm looking forward to that blog post! :-) For now, could you elaborate on what exactly you mean by transitioning from docker-compose to Nix? Did you start using systemd to orchestrate services? Were you still using Docker containers? If so, did you build the images with Nix? Etc.
