I don’t like Nix. It’s hard to use. It solves a problem that Docker already solved and Docker UX is much better. And it has a DSL that I think is unnecessary

  It really depends on your problem. If you need to patch docker images it often gets hairy.

  Docker definitely solves the problem imperfectly, though. Docker images simply don't compose, and this has caused me great pain: if you want image A plus image B, you can't do much better than a multi-stage build where you just magically know what you need to pull out of the first image. Nix, by contrast, composes perfectly, because packaging something for Nix involves precisely specifying what you need (as opposed to packaging something for Docker, which involves… splurging your package arbitrarily across a clean container).
