# 🐳 Docker Setup for Discord Fishbowl

This document explains how to use Docker with Discord Fishbowl for easy PostgreSQL, Redis, and ChromaDB setup.

## 🚀 Quick Start

### Option 1: Interactive Setup (Recommended)
```bash
python install.py
# Choose "PostgreSQL with Docker" when prompted
# Setup script will handle everything automatically
```

### Option 2: Manual Docker Setup
```bash
# Start services
./docker-services.sh start

# Or with PgAdmin for database management
./docker-services.sh admin
```

## 📋 Available Services

| Service | Port | Purpose | Admin URL |
|---------|------|---------|-----------|
| PostgreSQL | 5432 | Main database | - |
| Redis | 6379 | Caching & pub/sub | - |
| ChromaDB | 8000 | Vector embeddings | http://localhost:8000 |
| PgAdmin | 8080 | Database admin | http://localhost:8080 |

## 🔧 Docker Commands

### Service Management
```bash
# Start all services
./docker-services.sh start

# Start with database admin interface
./docker-services.sh admin

# Check service status
./docker-services.sh status

# View logs
./docker-services.sh logs

# Stop services
./docker-services.sh stop

# Restart services
./docker-services.sh restart

# Clean up (WARNING: deletes all data)
./docker-services.sh clean
```

### Direct Docker Compose
```bash
# Start services only
docker compose -f docker-compose.services.yml up -d

# Start with PgAdmin
docker compose -f docker-compose.services.yml --profile admin up -d

# Stop services
docker compose -f docker-compose.services.yml down

# View logs
docker compose -f docker-compose.services.yml logs -f
```

### Connecting Discord Fishbowl to Docker Services

When using Docker services, update your Discord Fishbowl configuration:

**config/fishbowl_config.json**:
```json
{
  "database": {
    "type": "postgresql",
    "host": "localhost",
    "port": 5432,
    "name": "discord_fishbowl",
    "username": "postgres",
    "password": "fishbowl_password"
  },
  "redis": {
    "enabled": true,
    "host": "localhost",
    "port": 6379,
    "password": "redis_password"
  },
  "vector_db": {
    "type": "chromadb",
    "host": "localhost",
    "port": 8000
  }
}
```

## 🐛 Troubleshooting

### Services Won't Start
1. Check if Docker is running: `docker info`
2. Check port conflicts: `lsof -i :5432` (PostgreSQL), `lsof -i :6379` (Redis)
3. Check logs: `./docker-services.sh logs`

### Permission Errors
```bash
# Fix Docker permissions (macOS/Linux)
sudo chmod +x docker-services.sh
```

### Data Persistence
- PostgreSQL data: Docker volume `fishbowl_postgres_data`
- Redis data: Docker volume `fishbowl_redis_data`
- ChromaDB data: Docker volume `fishbowl_chroma_data`

To backup data:
```bash
# Backup PostgreSQL
docker exec fishbowl_postgres pg_dump -U postgres discord_fishbowl > backup.sql

# Restore PostgreSQL
docker exec -i fishbowl_postgres psql -U postgres discord_fishbowl < backup.sql
```

### Reset Everything
```bash
# Stop and remove all data (WARNING: destructive)
./docker-services.sh clean

# Restart fresh
./docker-services.sh start
```

## 🔗 Integration with Install Script

The `install.py` script automatically:
1. Detects Docker availability
2. Offers Docker-based setup options
3. Creates `.env.docker` with your passwords
4. Starts services automatically
5. Configures Discord Fishbowl to use Docker services

## 🎯 Production Deployment

For production, consider:
1. Using the full `docker-compose.yml` (includes the app)
2. Setting strong passwords in environment variables
3. Using Docker secrets for sensitive data
4. Setting up proper network security
5. Regular backups of volumes
