Deployment
----------
-You'll need root access to customs.
+This runs on customs.hackerspace.pl, which is a NixOS box with its own independant configuration. It imports hscloud and builds the `hswaw.laserproxy` attribute. You can replicate this by running:
- bazel build --platforms=@io_bazel_rules_go//go/toolchain:openbsd_amd64 //hswaw/laserproxy
- ssh root@customs supervisorctl stop laserproxy
- scp bazel-bin/hswaw/laserproxy/laserproxy_/laserproxy root@customs:/var/laserproxy/laserproxy
- ssh root@customs supervisorctl start laserproxy
+ nix-build -A hswaw.laserproxy
+From the root of hscloud. To actually deploy it on customs, well, ssh there and upate `/etc/nixos/configuration.nix`. Some day its configuration might also get ported to hscloud.
