Deploying the developer edition on Earth

Companion to spec.md §17.5. Status: planned, nothing installed yet (2026-09-27).

The host
Nameearth (earth.andymccall.xyz, IPv6 ULA; 192.168.1.6 on the LAN)
OSUbuntu 26.04.1 LTS, x86_64, 4 cores, 31 GiB RAM
Disk/ 251 GB (95 GB free), /home 1 TB (944 GB free)
Already runningsshd :22, a Python service :6400, wren-nest :7842, retroplay-manager in Docker (:8080, :6670) with Postgres and a tetriblox server, two GitHub Actions runners (doomsdayonecom), Docker, containerd
Not installedRust toolchain, sqlite3 CLI, nginx or caddy, certbot
Accessssh -i ~/.ssh/earth_claude claude@earth; claude has passwordless sudo

Ports 7300 (HTTP) and 7343 (HTTPS) are free and are the hub's.

Steps

  1. Toolchain (as claude): curl https://sh.rustup.rs -sSf | sh -s -- -y --profile minimal, then sudo apt-get install -y build-essential pkg-config git.
  2. Source: from the development machine, rsync -a --delete --exclude target --exclude node_modules ~/development/oxygen ~/development/oxygenhub claude@earth:~/src/. Oxygen is never pushed to Git; rsync is the bootstrap, and after the hub runs, oxy push to the hub itself is the ongoing path.
  3. Build: cd ~/src/oxygenhub && cargo build --release.
  4. System user and data: sudo useradd --system --home /home/oxygenhub --create-home oxygenhub, sudo install -o oxygenhub -g oxygenhub -m 0755 target/release/oxygenhub /usr/local/bin/, sudo -u oxygenhub oxygenhub init --data /home/oxygenhub/data --admin andymccall (prints the first admin's one-time password).
  5. Service: /etc/systemd/system/oxygenhub.service running oxygenhub serve --data /home/oxygenhub/data as oxygenhub, Restart=on-failure, ProtectSystem=strict, ReadWritePaths=/home/oxygenhub/data, NoNewPrivileges=yes; sudo systemctl enable --now oxygenhub.
  6. TLS: the developer edition generates a self-signed certificate at init. Download the certificate from https://earth.andymccall.xyz:7343/.well-known/oxyhub-ca.pem (or over plain HTTP on port 7300) and point clients at it with oxy config remote.<name>.ca <file> or OXY_CA.
  7. First repositories: on the development machine, oxy remote add earth https://earth.andymccall.xyz:7343/andymccall/oxygen in each of oxygen, oxygen-vscode, oxygenhub, then oxy push earth.
  8. Updates: rsync, build, sudo install, sudo systemctl restart oxygenhub. A make deploy target in the hub wraps steps 2, 3 and 8.
