## Summary - Closes [#10](#10). - Deploys **SearxNG** on **ai-server-4080** (`10.0.0.128`) for [chat_backend#62](ai_ml_operations/chat_backend#62) / [PR #65](ai_ml_operations/chat_backend#65) grounded search. - New `roles/searxng/` (compose + JSON-enabled `settings.yml`), gated by `searxng_stack: true`, wired into `site.yml`. - **Host port 8088** (not 8080 — that is `dta_webapp` on this host). UFW allows `10.0.0.0/24` → `8088/tcp` only. ## Ops after merge ```bash ./scripts/provision.sh ai-server-4080 # or targeted: ansible-playbook playbooks/site.yml --limit ai-server-4080 --tags never # full site play includes searxng when searxng_stack ``` Then set in `chat_backend_prod.env` / `chat_backend_beta.env`: ```text SEARCH_PROVIDER=searxng SEARCH_FAILOVER_PROVIDER=ddgs SEARXNG_BASE_URL=http://10.0.0.128:8088 ``` Smoke test from any app host: ```bash curl -sG 'http://10.0.0.128:8088/search' --data-urlencode 'q=test' -d 'format=json' | head ``` ## Test plan - [ ] Provision ai-server-4080; confirm `docker ps` shows `searxng` - [ ] Confirm `:8088` responds with JSON; `:8080` still serves dta_webapp - [ ] Confirm UFW rule is LAN-only - [ ] From adama/roslin container network, curl SearxNG succeeds - [ ] Update chat_backend secrets to `:8088` and redeploy betaReviewed-on: #11

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).
