notplantsandClaude d29fa655c2 host: KillMode=process on the agent units so a rebuild stops nuking tmux
One tmux server hosts every agent session on this box and it lives in
cc-ci-loops.service's cgroup, so any rebuild touching that unit killed ALL sessions
(cc-ci, lichen, PO, pi). With KillMode=process systemd kills only the already-exited
launcher, not the cgroup — added to cc-ci-loops, lichen-orchestrator and
project-orchestrator. Trade-off: `systemctl stop` no longer tears agents down; do it
by hand.

Carries an in-flight nginx basicAuth block from the cc-ci agent that was already
uncommitted in this file and is now deployed with the 26.05 switch — committed here so
it is not lost, not authored by me.

cc-ci-orchestrator

⚠️ HISTORICAL. This README describes the retired Incus VM (100.116.55.106). The orchestrator now runs on Hetzner — the live host config is nix/hosts/cc-ci-orchestrator-hetzner/configuration.nix. See cc-ci-plan/plan-orchestrator-hetzner-migration.md for the current setup. Kept for history.

NixOS config for the cc-ci-orchestrator Incus VM (b1, project terraform-ci, tailnet 100.116.55.106) — the reboot-resilient host for the cc-ci Builder/Adversary loops + watchdog + orchestrator session, moved off the unstable 905 MiB Pi.

See cc-ci-plan/plan-orchestrator-migration.md for the full migration.

  • configuration.nix — the VM's NixOS config (channel-based, nixos-24.11). Deployed to /etc/nixos/configuration.nix on the VM. Provides: nix-ld (so the standalone Claude Code Bun binary runs), tmux/git/python/jq + tools, a 4 GB swapfile, direct ssh to cc-ci (the VM is a tailnet peer — no SOCKS proxy needed, unlike the Pi), an idempotent claude-install oneshot, and the cc-ci-loops supervisor service (defined, enabled in Phase D once the workspace is staged).

Deploy (until this is wired to a flake/auto-pull)

# copy configuration.nix to the VM, then:
ssh cc-ci-orchestrator 'nixos-rebuild switch'    # or run detached: see below

Over the (currently flaky) Pi→VM link, run the rebuild detached on the VM so an ssh/proxy drop doesn't abort it, e.g. systemd-run --unit=orch-rebuild --collect nixos-rebuild switch then poll journalctl -u orch-rebuild.

Status

  • Phase A: VM created (2 GB / 2 vCPU / 30 GB), on tailnet, ssh-able.
  • Phase B: this config (DRAFT) — nix-ld/claude validation pending on the VM.
  • Operator step pending (Phase C): claude auth login on the VM (device-code; can't be scripted).
  • Secrets to stage (Phase C, out-of-band): /srv/cc-ci/.testenv, ~/.ssh/cc-ci-root-ed25519, Incus mTLS certs, the sops master age key.
