Just some notes from my attempt at setting up Hydra.
No need for manual database creation and all that; just ensure that your PostgreSQL service is running (services.postgresql.enable = true;), and then enable the Hydra service (services.hydra.enable). The Hydra service will need a few more options to be set up, below is my configuration for it:
services.hydra = {
enable = true;
port = 3333;
| { config, lib, pkgs, ...}: | |
| with lib; | |
| { | |
| nix.package = pkgs.nixUnstable; | |
| nix.trustedUsers = [ "hydra" ]; | |
| nix.binaryCaches = [ "http://cache.example.org" "https://cache.nixos.org" ]; | |
| nix.buildMachines = [ |
| #! /usr/local/bin/fish | |
| if test -n "$HOME" ; | |
| set -xg NIX_LINK "$HOME/.nix-profile" | |
| # Set the default profile. | |
| if not test -L "$NIX_LINK" ; | |
| echo "creating $NIX_LINK" >&2 | |
| set -l _NIX_DEF_LINK /nix/var/nix/profiles/default | |
| /nix/store/cdybb3hbbxf6k84c165075y7vkv24vm2-coreutils-8.23/bin/ln -s "$_NIX_DEF_LINK" "$NIX_LINK" | |
| end |
| (defrecord Server [service-map] | |
| component/Lifecycle | |
| (start [component] | |
| (info :msg "Starting server.") | |
| (let [server (bootstrap/create-server (:service-map service-map))] | |
| (bootstrap/start server) | |
| (assoc component :server server))) | |
| (stop [component] | |
| (info :msg "Stopping server.") | |
| (update-in component [:server] bootstrap/stop))) |
