Oskar Kapala 01b7758fe6 feat(node-agent): implement health monitor and safe cleanup policy
scripts/monitor/health-monitor.sh (new):
- Standalone bash health monitor: disk/RAM/CPU checks + docker container health
- Per-node-type cleanup policy enforced:
    lte_node  (chelsty-infra, chelsty-ha): NO cleanup, no docker ops
    sd_card   (piha, saturn): dangling images + containers, rate-limited once/24h
    ai_node   (solaria): dangling + containers + build cache, NEVER -a
    standard  (vps): dangling + containers + build cache + CP filesystem rotation
- VPS filesystem rotation: completed/failed actions >7d, deploy logs >30d,
  events >3d AND past observer checkpoint
- Emits structured JSON events (node_health, disk_pressure, high_memory, high_cpu,
  containers_not_running, healthcheck_failed)

services/node-agent/ (new):
- Python daemon (node_agent.py): same policy as bash script, Docker SDK
  for container checks and cleanup, /proc for system metrics
- Optional event shipping to VPS via rsync+SSH (VPS_EVENTS_HOST env var)
- Dockerfile: python:3.11-slim + openssh-client + rsync + docker>=6.0
- docker-compose.yml: mounts docker socket, /opt/homelab, repo read-only

observer.py:
- Handle node_health: update node status + disk/mem/cpu metrics, clear disk_pressure
- Handle disk_pressure: record severity on node, clear when healthy
- Handle high_memory / high_cpu: record pressure level for correlation

supervisor.py:
- Add NO_DISK_CLEANUP_NODES = {chelsty-infra, chelsty-ha}
- reconcile() step 3: generate disk_cleanup actions for nodes with high disk pressure
- _generate_disk_cleanup_recommendation(): stable ID disk-cleanup-{node},
  checks all active states, risk=guarded (operator approval required)

executor.py:
- Handle disk_cleanup action type via _execute_disk_cleanup()
- Commands come from action payload; safety gate rejects any command touching
  /opt/homelab/data/, /opt/homelab/config/, /opt/homelab/state/, or rm -rf /

hosts/*/services.yaml:
- Rename stability-agent -> node-agent on piha, vps, solaria, chelsty-infra
- Add node-agent to chelsty-ha (previously missing)
- Add cleanup policy notes to LTE node comments

Homelab Codex

GitOps-lite orchestration for a distributed homelab environment.

Architecture

The homelab consists of several nodes connected via a Tailscale internal mesh.

Host Role Description
SATURN Primary Node Development, orchestration, and git source of truth (commit node).
SOLARIA Compute Node GPU, inference, and heavy compute workloads.
PIHA Infra Node Core infrastructure services, automation, and monitoring.
VPS Edge Node Public ingress, reverse proxy, and edge services.

Repository Structure

Getting Started

  1. Standardization: Follow the Infrastructure Standards.
  2. Deployment: See Deployment Conventions for how to roll out changes.
  3. SATURN: Remember that SATURN is the only node where commits should be made.

Documentation Index


Note: This repository documents the state of the homelab. Runtime state lives outside the repository in /opt/homelab.
