# cc-ci on Hetzner Cloud — the canonical STANDALONE CI-server host.
# Hardware + networking + host identity only; every cc-ci service comes from the shared
# `nixosModules.cc-ci-server` module (nix/modules/default.nix), which flake.nix adds to this
# host. The same module builds the combined CI-server + orchestrator host declared in
# recipe-maintainers/cc-ci-orchestrator (`#cc-ci`), which is where cc-ci is moving (2026-09).
#
# To apply after `terraform apply` + nixos-infect:
#   git clone --recursive https://git.autonomic.zone/recipe-maintainers/cc-ci.git /etc/cc-ci
#   install -m600 <age-private-key> /var/lib/sops-nix/key.txt
#   nixos-rebuild switch --flake 'git+file:///etc/cc-ci?submodules=1#cc-ci'
