Global build options

Like rbuild, rsdk also allows defining global build options. The underlying mechanical is the same: predefined environmental variables. However, since we use devenv to manage the environment, the way to define them is also changed.

For now, you will need to add your definitions in devenv.local.nix file. We provide devenv.local.nix.example as a reference for file structure. This is also what we use in the office, but the server is locally hosted, so you won't be able to use it.

Example: set up local apt cache to speed up build

If you want to speed up image building time, one way is to use a locally hosted apt cache to reduce download time.

First, copy devenv.local.nix.example to devenv.local.nix. You can then remove RSDK_OPTION_REPO_SUFFIX if you do not want to build test image by default, and then change RSDK_OPTION_*_MIRROR to your own address.

Below are example NixOS configuration to set up a local apt cache service, as well as the mirror definition for acng.conf file. They may not be complete, so adjust to match your own use case.

{
  virtualisation = {
    oci-containers = {
      backend = "podman";
      containers = {
        acng = {
          image = "docker.io/mbentley/apt-cacher-ng";
          ports = [
            "3142:3142"
          ];
          volumes = [
            "/home/acng/containers/acng.conf:/etc/apt-cacher-ng/acng.conf"
            "/home/acng/containers/acng/:/var/cache/apt-cacher-ng/"
          ];
          environment = {
            PUID = "1000";
            PGID = "100";
            TZ = "Asia/Shanghai";
          };
        };
      };
    };
  };
}
