forgejo-actions/README.md

This repository is just a for auto updating the default nix docker image for forgejo runner on my instance.

Setup:

As you cannot run a forgejo runner with nixos/nix due to it not having node by default, you need to manually build and upload the first image. After that you can specify your instance's image as a base image for forgejo runner.

Manual upload of the first image:

  USERNAME="tamipes"
  URL="git.tami.moe"
  IMG_NAME="nix"
  nix build --extra-experimental-features "flakes nix-command" .
  docker load -i result
  docker image tag "$IMG_NAME" "$URL/$USERNAME/$IMG_NAME:latest"
  docker login "https://$URL"
  docker push "$URL/$USERNAME/$IMG_NAME"
  rm result # don't forget to cleanup the GC root

  # I also tag with the date, but this might be unneeded
  docker image tag "$IMG_NAME" "$URL/$USERNAME/$IMG_NAME:latest$(date --iso-8601)"
  docker push "$URL/$USERNAME/$IMG_NAME"

Extra info

• These image are essentially still "based" on nixos/nix, but it builds it with nodejs(+extras) included. Checkout the flake.nix!
  • it does not use nixos/nix as a base image, but uses the same build script and adds extra stuff
  • nixpkgs manual
  • nixos/nix build script
