## Summary - Closes [#24](#24). - Register `college_craft` in `app_catalog` (`type: django`, repo `ai_ml_operations/college_craft`, default branch `master`). - Add `host_apps` prod `:8006` / beta `:8016` on **adama**, **roslin**, **starbuck**, **apollo**, and **ai-server-4080**. - dj-queue **worker singleton on adama** only (`compose_profiles: [worker]`); other hosts web-only. - Document ports, NPM hosts, Postgres DBs, secrets, Nominatim (`10.0.0.128:8089`), and the app-repo `--app client_site` leftover. - Add `college_craft` to `scripts/deploy.sh` `--app` help. ## Out of scope (ops, after merge) - Create Postgres DBs `college_craft` / `college_craft_beta` on `10.0.0.230` and grant `westfarn`. - Write control-node secrets `~/Documents/secrets/college_craft/college_craft_{prod,beta}.env`. - NPM: `collegecraft.com` (+ www) → `:8006`; `college-craft-preview.aimloperations.com` → `:8016`. - Smoke deploy after secrets + DBs exist: ```bash ~/Documents/repos/server-infra/scripts/deploy.sh --app college_craft --env beta --ref master ~/Documents/repos/server-infra/scripts/deploy.sh --app college_craft --env prod --ref master ``` ## Test plan - [ ] Confirm `app_catalog.college_craft` matches other django apps (`compose_file`, `migrate_cmd`). - [ ] Confirm ports 8006/8016 unused elsewhere and match across all five hosts. - [ ] Confirm only adama has `compose_profiles: [worker]` for college_craft. - [ ] After secrets + DBs: deploy beta then prod; `/healthz/` up on both; prod holding page, beta full site.

Ansible provisioning and deployment for homelab web servers.
Quick Start
# Install collections (once)
ansible-galaxy collection install -r requirements.yml
# Bootstrap SSH key to each host (one-time, before Ansible)
ssh-copy-id westfarn@10.0.0.77
ssh-copy-id westfarn@10.0.0.176
ssh-copy-id westfarn@10.0.0.44
ssh-copy-id westfarn@10.0.0.7
# First-time only: passwordless sudo on each new host (before first provision)
ssh -t westfarn@10.0.0.176 # repeat for each host IP
# on the host:
echo 'westfarn ALL=(ALL) NOPASSWD:ALL' | sudo tee /etc/sudoers.d/westfarn
sudo chmod 440 /etc/sudoers.d/westfarn
exit
# Test connectivity to one host
ansible adama -m ping
# Provision one host (dry run first) — includes Alloy log/metrics agent
./scripts/provision.sh adama --check
./scripts/provision.sh adama
# Control node: Alloy + Loki + Prometheus + Grafana
./scripts/provision.sh ai-server-4080
# Provision all hosts
./scripts/provision.sh
See IMPLEMENTATION.md for full architecture, CI/CD plan, and phase breakdown.
Observability (Alloy → Loki / Prometheus → Grafana): docs/OBSERVABILITY.md · docs/GRAFANA_USAGE.md
Provision installs Alloy on every host. On ai-server-4080 it also starts
the central Loki / Prometheus / Grafana stack (observability_stack: true).
