Anyone know how to get hydra to copy build outputs to hydra’s /nix/store from a build machine? Seems like it doesn’t happen by default unless I’m missing something. Just using
nix-ssh to serve the cache for now.
when a build is done on a build machine, I see only two files on hydra-server:
/nix/var/nix/gcroots/hydra/hks67kr0wvd5kl9hk8yinmnkx6lviapi-python3.7-mlflow-1.4.0 . Nothing in /nix/store
only clue I get from journalctl is
hydra-queue-runner: copying path '/nix/store/hks67kr0wvd5kl9hk8yinmnkx6lviapi-python3.7-mlflow-1.4.0' (60848440 bytes, compressed 0.0% in 39 ms) to binary cache , and yet I see nothing in store. Plenty of space on disk drive
