I while ago here I asked about using nix with drone.io (a CI system which uses docker), to deal with push based tests. I previously reported back with a solution with gitlab, but I did end up with a workable (not perfect) solution for drone.
On the 'drone agent' machine run this once:
# docker volume create nix
# docker run --rm -v nix:/newnix nixos/nix cp -a /nix/store /nix/var /newnix
in the .drone.yml files:
And whenever you want to update nixchannel:
# docker run -v nix:/nix/ --rm -ti nixos/nix nix-channel --update
This will share the /nix directory with every build, so rebuild (and
downloads!) are kept to a minimum.
Maybe it helps someone.
