Because docker for Mac has always kind of sucked, I’ve moved on to making nix-based development environments and I’ve been very pleased so far.

Lately I’ve been trying https://devenv.sh/ and it works great!

I haven’t tried it for ruby, though I have used vanilla nix shell for ruby projects before and it worked quite well after I over-rode GEM_PATH and GEM_HOME to the correct values.

I've been using Colima lately and it's been a great experience. The only thing that didn't quite work was pushing an image to AWS ECR, but pulling images, building images (with BuildKit), and running containers all worked fine, and faster than Docker.

isn’t Buildkit Docker?
