This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Repository Overview

This repository manages a homelab infrastructure with self-hosted services running across 3 nodes using standalone Docker Compose on all nodes. (Docker Swarm was fully dismantled on 2026-04-01.)

Cluster Architecture

Nodes:

  • hf-pdocker-01 (192.168.86.192) - Core infrastructure + Frigate NVR - RESTORED (2026-03-08)
  • hf-pdocker-02 (192.168.86.100) - Dev tools, utilities
  • bart (192.168.86.167) - Media stack, OpenVAS

Synology NAS (192.168.86.30) - Centralized NFS storage for all service data

Access: Username glyptic, password &Rip8a115 (has sudo access on all nodes)

Working with This Repository

Environment Context

You are working in a WSL 2 environment on Windows. Docker is NOT directly available in WSL - all Docker operations must be performed by connecting to the remote nodes via SSH.

Critical: Docker is not available locally in WSL. All Docker operations must be performed by connecting to the remote nodes via SSH.

Storage Architecture

All service data lives on the Synology NAS via NFS, mounted at /mnt/docker-data on all 3 nodes.

/mnt/docker-data/ (NAS: 192.168.86.30:/volume1/Docker)
├── configs/          # Application configs
├── databases/        # Database data directories
├── media/            # Frigate recordings
├── traefik/          # Let's Encrypt certs
└── compose/          # Standalone compose files per node
    ├── hf-pdocker-01/{frigate,frigate-notify,clip-service,matrix,smarthome,guacamole,ai-agents,traefik,adguard}/
    ├── hf-pdocker-02/{unifi,gitea,semaphore,wikijs,vaultwarden,actual-budget,mcpo,trivy,watchtower}/
    └── bart/{media,openvas,watchtower}/

NFS mount (all nodes): 192.168.86.30:/volume1/Docker /mnt/docker-data nfs rw,soft,timeo=300,intr,_netdev,nfsvers=3,nofail,x-systemd.after=network-online.target,x-systemd.mount-timeout=60s 0 0 Note (hf-pdocker-01): Both NFS mounts hardened with nofail,x-systemd.after=network-online.target,x-systemd.mount-timeout=60s on 2026-05-20 to prevent boot-time race (network not up when NFS tried to mount, cascading ~10 container failures).

NFS + Databases: Database containers on NFS require user: "1024:100" to avoid chown failures from NFS root_squash. UID 1024 is the NAS anonymous user.

Repository File Structure

stacks/              # LEGACY Swarm stack definitions (Swarm dismantled 2026-04-01, kept for reference)

│   └── {service}/.env
└── bart/            # Media stack & OpenVAS

Deployment Workflow

All services (compose/):

  1. Edit compose file in compose/{node}/{service}/docker-compose.yml
  2. SCP to NAS path or node, then: cd /mnt/docker-data/compose/{node}/{service} && docker compose up -d

Service Architecture Patterns

Network Patterns:

  • Compose services: Bridge networks for service isolation
  • Public services (Traefik): Traefik labels + dynamic config files in /mnt/docker-data/traefik/dynamic/

Database Patterns:

  • PostgreSQL: postgres:15-alpine or postgres:16-alpine
  • MySQL: mysql:8.0 (Guacamole, Semaphore)
  • MongoDB: mongo:7.0 (Unifi)
  • Always add com.centurylinklabs.watchtower.enable=false label
  • Always add user: "1024:100" for NFS-backed database volumes

Volume Patterns:

  • Application data: /mnt/docker-data/configs/{service-name}/
  • Database data: /mnt/docker-data/databases/{service-name}-db/
  • Traefik certs: /mnt/docker-data/traefik/letsencrypt/

Port Conflict Notes

Port conflicts already resolved:

  • Port 8000: Freed (MCPO moved to 8001, Portainer moved elsewhere)
  • Port 3000: AdGuard Home (Gitea moved to 3003)
  • Port 3001: Grafana (Semaphore moved to 3004)
  • Port 5000: Frigate uses host networking (registry container stopped)
  • AI Agent ports re-spaced (2026-03-15): openclaw 2026.3.13 uses gateway+2 and gateway+3 for browser/chrome-relay. Agents spaced 5 apart: margaret=18790, spirit=18795

Critical Configuration Preservation

Encryption Keys & Passwords

  • Semaphore: SEMAPHORE_ACCESS_KEY_ENCRYPTION encrypts sensitive data
  • Always check for existing encryption keys before generating new ones

Database Version Matching

Match the PostgreSQL/MySQL version to existing data directory format. Check logs for version mismatch errors.

Post-Change Checklist (MANDATORY)

After ANY infrastructure change (deploy, remove, reconfigure, add service, change ports, modify Traefik routes), you MUST complete ALL of these before reporting done:

  1. CLAUDE.md — Update service lists, ports, node assignments if changed
  2. MEMORY.md — Add/update relevant memory entries
  3. Prometheus probes — Add/remove blackbox targets, hot-reload Prometheus
  4. Wiki — Launch documentation-keeper agent to update wiki pages (run in background)

Do NOT wait for the user to ask. Do NOT skip "because the change was small." Every change gets documented.

Common Operations

Deploy/Update a Compose Service

  1. Edit compose/{node}/{service}/docker-compose.yml
  2. SSH to the target node and run: 
    cd /mnt/docker-data/compose/{node}/{service}
docker compose up -d

Troubleshoot

# On target node:
docker compose -f /mnt/docker-data/compose/{node}/{service}/docker-compose.yml logs --tail 100
docker ps --format "table {{.Names}}\t{{.Status}}"

Check Cluster Health

# On each node:
docker ps                         # Local containers

Data Management

Storage

All persistent data on NAS at /mnt/docker-data/:

  • configs/ - Application configurations
  • databases/ - Database volumes
  • media/ - Frigate recordings
  • traefik/ - SSL certificates

NAS Dependency

Risk: NAS failure = all services fail (single point of failure)

  • NFS mount uses soft,timeo=300 for graceful timeout
  • Synology should have "Restart automatically after power failure" enabled
  • Original data backups remain on local /data/configs/ on hf-pdocker-01

Specialized Agents

vault-credential-manager

Use for: Storing/retrieving credentials from Vaultwarden

documentation-keeper

Use for: Creating/updating documentation in Wiki.js

Known Issues & Workarounds

  1. NFS root_squash: Database containers need user: "1024:100" to avoid chown failures on NAS volumes
  2. Telegraf Docker Input: Disabled due to Docker socket permission issues across nodes
  3. Watchtower API Version: Requires DOCKER_API_VERSION=1.44
  4. InfluxDB Connection: Telegraf may show timeout errors if InfluxDB is not running
  5. Frigate cameras: Cameras on 192.168.44.x subnet may show RTSP timeouts (check camera network)
  6. Registry container: Stopped on hf-pdocker-01 to free port 5000 for Frigate
  7. systemd-resolved DNSStubListener: Must be disabled on any node running AdGuard Home (port 53 conflict). Fix: /etc/systemd/resolved.conf.d/nostub.conf with DNSStubListener=no, then systemctl restart systemd-resolved. Applied on hf-pdocker-01 and hf-pdocker-02.
  8. NFS boot-mount race (hf-pdocker-01): NFS mounts failed at boot (network not ready in time). Fixed 2026-05-20 by adding nofail,x-systemd.after=network-online.target,x-systemd.mount-timeout=60s to both fstab entries. If mounts are missing after reboot: sudo mount /mnt/docker-data && sudo mount /mnt/infrastructure.
  9. Guacamole schema: App image pinned to guacamole/guacamole:1.6.0 + guacd:1.6.0 with Watchtower disabled. DB schema was reset to fresh 1.6.0 on 2026-05-20 (old schema was non-standard). Recreate connections after any DB reset.
  10. Gitea image: Pinned to gitea/gitea:1.26.1 with Watchtower disabled (2026-05-20). Watchtower previously pulled broken :latest images causing missing git binary errors.
  11. Home Assistant reverse proxy: Config at /mnt/docker-data/configs/homeassistant/configuration.yaml (no hyphen). Must have http: use_x_forwarded_for: true + trusted_proxies: [172.16.0.0/12, 127.0.0.1] or proxied requests return 400.
