Nix Docker builder

Heavy WIP

Needing to build Linux derivations on macOS, but no Linux machine nearby and nixos/nix image is inconvenient to set up*?

Use with lima, or colima, or even Docker.app

* Right now distributed builds have quite subpar experience, so it is not advisable for beginner to use them.

Setting up

Building builder image on Linux

Easiest choice; nix build .#dockerImage, scp image to macOS and import.

Building builder image on macOS with Docker/-compatible

Run ./hack/bootstrap_image.sh, and import image from result file in repository directory

Launching

You can use ./hack/run.sh. It will set up the builder for your user (including needed modifications to ~/.ssh/config etc.)

Using with Nix

See https://nixos.org/manual/nix/stable/advanced-topics/distributed-builds.html

This repository provides a nixb wrapper to invoke nix with remote builders flag.

Testing

./test/remote_build/test.sh
cat ./test/remote_build/result
