# CLAUDE.md

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

## Overview

Multi-service Docker Compose stack named "falcon" managing production services on pivoine.art domain. Uses Arty for configuration management with centralized environment variables and custom scripts.

## Architecture

### Compose Include Pattern
Root `compose.yaml` uses Docker Compose's `include` directive to orchestrate multiple service stacks:
- **core**: Shared PostgreSQL 16 + Redis 7 infrastructure
- **proxy**: Traefik reverse proxy with Let's Encrypt SSL
- **sexy**: Directus 11 CMS + SvelteKit frontend
- **awsm**: Next.js application with SQLite
- **track**: Umami analytics (PostgreSQL)
- **mattermost**: Team collaboration and chat platform (PostgreSQL)
- **scrapy**: Scrapyd web scraping cluster (scrapyd, scrapy, scrapyrt)
- **n8n**: Workflow automation platform (PostgreSQL)
- **stash**: Filestash web-based file manager
- **links**: Linkwarden bookmark manager (PostgreSQL + Meilisearch)
- **vault**: Vaultwarden password manager (SQLite)
- **joplin**: Joplin Server note-taking and sync platform (PostgreSQL)
- **kit**: Unified toolkit with Vert file converter and miniPaint image editor (path-routed)
- **jelly**: Jellyfin media server with hardware transcoding
- **drop**: PairDrop peer-to-peer file sharing
- **ai**: AI infrastructure with Open WebUI, Crawl4AI, and pgvector (PostgreSQL)
- **asciinema**: Terminal recording and sharing platform (PostgreSQL)
- **restic**: Backrest backup system with restic backend
- **netdata**: Real-time infrastructure monitoring
- **sablier**: Dynamic scaling plugin for Traefik
- **vpn**: WireGuard VPN (wg-easy)

All services connect to a single external Docker network (`falcon_network` by default, defined by `$NETWORK_NAME`).

### Environment Management via Arty
Configuration is centralized in `arty.yml`:
- **envs.default**: All environment variables with sensible defaults
- **scripts**: Common Docker Compose and operational commands
- Variables follow naming pattern: `{SERVICE}_COMPOSE_PROJECT_NAME`, `{SERVICE}_TRAEFIK_HOST`, etc.

Sensitive values (passwords, secrets) live in `.env` and override arty.yml defaults.

### Traefik Routing & Security Architecture
Services expose themselves via Docker labels:
- HTTP → HTTPS redirect on `web` entrypoint (port 80)
- SSL termination on `web-secure` entrypoint (port 443)
- Let's Encrypt certificates stored in `proxy` volume
- Path-based routing: `/api` routes to Directus backend, root to frontend
- Compression middleware applied via labels
- All routers scoped to `$NETWORK_NAME` network

**Security Features:**
- **TLS Security**: Minimum TLS 1.2, strong cipher suites (ECDHE, AES-GCM, ChaCha20), SNI strict mode
- **Security Headers**: HSTS (1-year), X-Frame-Options, X-XSS-Protection, Content-Type-Options, Referrer-Policy, Permissions-Policy
- **Dynamic Configuration**: Security settings in `proxy/dynamic/security.yaml` with auto-reload
- **Rate Limiting**: Available middlewares (100 req/s general, 30 req/s API)
- **HTTP Basic Auth**: Scrapyd protected with username/password authentication

### Database Initialization
`core/postgres/init/01-init-databases.sh` runs on first PostgreSQL startup:
- Creates `directus` database for Sexy CMS
- Creates `umami` database for Track analytics
- Creates `mattermost` database for Mattermost chat platform
- Creates `n8n` database for workflow automation
- Creates `linkwarden` database for Links bookmark manager
- Creates `joplin` database for Joplin Server
- Creates `asciinema` database for Asciinema terminal recording server
- Grants privileges to `$DB_USER`

## Common Commands

All commands use `pnpm arty` (leveraging scripts in arty.yml):

### Stack Management
```bash
# Start all services
pnpm arty up

# Stop all services
pnpm arty down

# View running containers
pnpm arty ps

# Follow logs for all services
pnpm arty logs

# Restart all services
pnpm arty restart

# Pull latest images
pnpm arty pull

# View rendered configuration (with variables substituted)
pnpm arty config
```

### Network Setup
```bash
# Create external Docker network (required before first up)
pnpm arty net/create
```

### Database Operations (Sexy/Directus)
```bash
# Export Directus database + schema snapshot
pnpm arty db/dump

# Import database dump + apply schema snapshot
pnpm arty db/import

# Export Directus uploads directory
pnpm arty uploads/export

# Import Directus uploads directory
pnpm arty uploads/import
```

### Deployment
```bash
# Sync .env file to remote VPS
pnpm arty env/sync
```

**Volume Mounting**:
All Docker volumes are mounted read-only to `/volumes/` with prefixed names (e.g., `backup_core_postgres_data`) to avoid naming conflicts with other compose stacks.

**Configuration Management**:
- `config.json` template in repository defines all backup plans
- On first run, copy config into volume: `docker cp restic/config.json restic_app:/config/config.json`
- Config version must be `4` for Backrest 1.10.1 compatibility
- Backrest manages auth automatically (username: `valknar`, password set via web UI on first access)

**Important**: The backup destination path `/mnt/hidrive/users/valknar/Backup` must be accessible from the container. Ensure HiDrive is mounted on the host before starting the backup service.

## Volume Management

Each service uses named volumes prefixed with project name:

- `core_directus_uploads`, `core_directus_bundle`: Directus media/extensions
- `awesome_data`: AWSM SQLite database
- `mattermost_config`, `mattermost_data`, `mattermost_plugins`: Mattermost chat and configuration
- `scrapy_scrapyd_data`, `scrapy_scrapy_code`: Scrapy spider data and code
- `n8n_n8n_data`: n8n workflow data
- `stash_filestash_data`: Filestash configuration and state
- `links_data`, `links_meili_data`: Linkwarden bookmarks and Meilisearch index
- `vault_data`: Vaultwarden password vault (SQLite database)
- `joplin_data`: Joplin note-taking data
- `jelly_config`: Jellyfin media server configuration
- `ai_postgres_data`, `ai_webui_data`, `ai_crawl4ai_data`: AI stack databases and application data
- `netdata_config`: Netdata monitoring configuration
- `restic_data`, `restic_config`, `restic_cache`, `restic_tmp`: Backrest backup system
- `proxy_letsencrypt_data`: SSL certificates

Volumes can be inspected with:
```bash
docker volume ls | grep falcon
docker volume inspect <volume_name>
```

## Security Configuration

### HTTP Basic Authentication
Protected services (Scrapy, VERT, Proxy dashboard) use HTTP Basic Auth via Traefik middleware:
- **Shared credentials** stored in `.env` as `AUTH_USERS`
- Format: `username:$apr1$hash` (Apache htpasswd format)
- Generate new hash: `openssl passwd -apr1 'your_password'`
- Remember to escape `$` signs with `$$` in `.env` files

**Protected Services:**
- Scrapy (scrapyd + UI)
- VERT (file converter)
- Traefik Proxy dashboard

**To update credentials:**
```bash
# Generate hash
echo "username:$(openssl passwd -apr1 'new_password')"

# Update .env with shared credentials
AUTH_USERS=username:$$apr1$$hash$$here

# Sync to VPS
rsync -avzhe ssh .env root@vps:~/Projects/docker-compose/

# Restart services
ssh -A root@vps "cd ~/Projects/docker-compose && arty restart"
```

### Security Headers & TLS
Global security settings applied via `proxy/dynamic/security.yaml`:
- **TLS**: Minimum TLS 1.2, strong ciphers only, SNI strict mode
- **Headers**: HSTS, X-Frame-Options, CSP, Referrer-Policy, etc.
- **Rate Limiting**: Available middlewares for DDoS protection

Test security:
```bash
# Check headers
curl -I https://scrapy.pivoine.art

# SSL Labs test
# Visit: https://www.ssllabs.com/ssltest/analyze.html?d=scrapy.pivoine.art
```

### Modifying Security Settings
Edit `proxy/dynamic/security.yaml` to customize:
- TLS versions and cipher suites
- Security header values
- Rate limiting thresholds

Traefik automatically reloads changes (no restart needed).

## Troubleshooting

### Services won't start
1. Ensure external network exists: `pnpm arty net/create`
2. Check if services reference correct `$NETWORK_NAME` in labels
3. Verify `.env` has required secrets (compare with `arty.yml` envs.default)

### SSL certificates failing
1. Check `ADMIN_EMAIL` is set in `.env`
2. Ensure ports 80/443 are accessible from internet
3. Inspect Traefik logs: `docker logs proxy_app`

### Database connection errors
1. Check PostgreSQL is healthy: `docker ps` (should show healthy status)
2. Verify database exists: `docker exec core_postgres psql -U $DB_USER -l`
3. Check credentials match between `.env` and service configs

### Directus schema migration
- Export schema: `pnpm arty db/dump` (creates `sexy/directus.yaml`)
- Import to new instance: `pnpm arty db/import` (applies schema snapshot)
- Schema file stored in `sexy/directus.yaml` for version control
