## Summary - Fail when `--app` / `--env` match no `host_apps` row (was silent no-op) - Fail when `--app` missing from `app_catalog` Prevents "deploy succeeded" that only refreshed web-static nginx while skipping Django — what happened on [chat_backend run 205](https://git.aimloperations.com/ai_ml_operations/chat_backend/actions/runs/205) before `chat_backend` was registered on master. ## Test plan - [ ] `./scripts/deploy.sh --app does_not_exist --env prod` should fail with catalog message - [ ] `./scripts/deploy.sh --app chat_backend --env prod` should proceed with Django once catalog/host_apps presentReviewed-on: #6

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
# 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).
