hacc nixfiles

welcome to hacc nixfiles (haccfiles). this is the code describing our nix-based infrastructure.

structure

• default.nix: Entrypoint to the config
• common/: configuration common to all hosts
• desktop/: desktop-relevant communication
• modules/: home-grown modules for hacc-specific services
• nix/: sources files, managed with niv
• pkgs/: packages we built and don't want to upstream

working with the haccfiles

deploy:

nix build -f . deploy.$hostname && ./result switch

$hostname can be replaced with any hostname or group

committing to haccfiles

• Golden Rule: DO NOT COMMIT TO MAIN
  • exceptions apply, if you are not sure where to commit, don't commit to main
• split up commits, every commit is one atomic change
  • e.g. no big "did some changes" but instead "updated service x", "updated service y", "update service z"
• follow the commit format: "$prefix$place: $change"
  • prefix: one of fixup, nothing
  • place: one of "modules/$module", "$hostname/service", "common/($place)", "pkgs/$pkgs" or "sources"
  • change: describe your change, don't go over the character limit where git starts hiding/wrapping
• Exception: autogenerated messages (merge commits, reverts, etc)
