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).
