# CLAUDE.md

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)

compose/             # Standalone Compose definitions (deployed per-node)
├── hf-pdocker-01/   # Core infrastructure + Frigate
├── hf-pdocker-02/   # Dev tools & utilities
│   ├── {service}/docker-compose.yml
│   └── {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/`

**bart (192.168.86.167):**
- Farm Agent: :8889
- Jellyfin: :8096

**GPU Machine (192.168.86.150, RTX 3090):**
- **NOTE (2026-07-05):** .150 is actually the user's **Windows workstation** (runs the WSL/Claude Code session), not a headless Linux server. It runs **Docker Desktop** (WSL2 backend, RTX 3090 GPU passthrough working) alongside **UniFi OS Server** (Podman). Docker Desktop panics if UniFi/Podman claims `\\.\pipe\docker_engine` first — start Docker Desktop before UniFi OS Server. See memory `docker-desktop-unifi-podman-conflict`.
- **FRIDAY Voice replaced VoiceCoach (2026-07-05).** VoiceCoach fully decommissioned (v1+v2 removed from hf-pdocker-01; voice.hobbs.farm route removed). See memory `friday-voice`.
- [COMPOSE] **FRIDAY Voice stack (all on .150 Docker Desktop, via `docker.exe -c desktop-linux`):**
  - **voicecoach-speaches-gpu**: :8000 — GPU Whisper large-v3-turbo (STT) + Kokoro-82M af_nova (TTS), CUDA float16. Compose: `compose/gpu-machine/voicecoach-speaches/`.
  - **hermes**: `nousresearch/hermes-agent:latest` gateway — FRIDAY's reasoning agent. Settings transferred from WSL `~/.hermes` into named volume `hermes-data`. Compose: `compose/gpu-machine/hermes/`.
  - **friday-voice**: :8320 — push-to-talk console. Calls speaches (`host.docker.internal:8000`) + hermes (`docker exec hermes hermes -Q` via wrapper). Public: **coach.hobbs.farm** → :8320. Compose: `compose/gpu-machine/friday-voice/`.
- Ollama: :11434 (qwen2.5:14b, Hermes-4.3-36B-GGUF, others)

### 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:
   ```bash
   cd /mnt/docker-data/compose/{node}/{service}
   docker compose up -d
   ```

### Troubleshoot

```bash
# 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

```bash
# 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.
12. **hf-pdocker-01 memory pressure (2026-07-05)**: Node runs hot (~15/23GB, chronic swap). Mitigations applied: `vm.swappiness` lowered 60→10 (persisted in `/etc/sysctl.d/99-swappiness.conf`), and VoiceCoach (v1+v2, ~10 containers) fully removed (replaced by FRIDAY Voice on .150). Frigate is the main consumer (~9GB/12GB). Frigate has no semantic-search/face/LPR features enabled.
13. **Docker Desktop vs UniFi OS Server pipe conflict (Windows box .150, 2026-07-05)**: Both fight over `\\.\pipe\docker_engine`; Docker Desktop's backend nil-panics ("backend exited before becoming ready") if Podman wins. Fix: let Docker Desktop (auto-starts at login) claim the pipe first, launch UniFi OS Server manually after. Full detail in memory `docker-desktop-unifi-podman-conflict`.
14. **MySQL InnoDB corruption on NFS**: `semaphore-db` (mysql:8.0 on NFS) hit system-tablespace page corruption and crash-looped 3789× (2026-07-11), same class as the Guacamole-on-NFS issue (#9). Recovered in-place via `--innodb-force-recovery=1` → mysqldump → fresh volume → reimport (DB was empty, no data lost); admin recreated with `semaphore user add`. Any MySQL DB on NFS is at risk — prefer LOCAL storage like guacamole-db. See memory `semaphore-db-nfs-corruption`.
15. **litellm hangs after DB blip**: litellm does NOT self-recover from a transient `litellm-db` disconnect — it loops on "Prisma DB reconnect failed" forever; needs manual `docker restart litellm`. Its healthcheck was fixed from `curl` (absent from image, permanent false-unhealthy) to a python urllib check (2026-07-11).
