## Summary Implements [#7](#7): register **beta** workloads for `chat_backend` and `chat_web_app`, matching the existing `dta_service` / `dta_webapp` pattern. - Enable `host_apps` beta entries on **adama**, **roslin**, and **ai-server-4080** (`chat_backend` **8013**, `chat_web_app` **8083**) - Update `IMPLEMENTATION.md` apps / ports / NPM / roadmap tables for chat beta + prod - Prod chat entries unchanged ## Ops follow-ups (outside this PR) - Create Postgres DB `chat_backend_beta` + grant `westfarn` - Add `~/Documents/secrets/chat_backend/chat_backend_beta.env` (mode 600) - NPM: `beta.chat.aimloperations.com` → `*:8083`; `beta.chatbackend.aimloperations.com` → `*:8013` - Smoke: `./scripts/deploy.sh --app chat_backend --env beta --ref <sha>` and same for `chat_web_app` Companion app tickets: [chat_backend#26](ai_ml_operations/chat_backend#26), [chat_web_app#35](ai_ml_operations/chat_web_app#35) ## Test plan - [ ] Confirm beta rows present in all three `host_vars` - [ ] After merge + ops setup: deploy beta for both apps succeeds - [ ] Prod chat deploys still work on 8003 / 8082 - [ ] NPM beta domains route to 8013 / 8083Reviewed-on: #8
server-infra
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).
