# Vaultwarden Bitwarden Alternative Template

## Overview
Vaultwarden is an alternative implementation of the Bitwarden server API written in Rust, compatible with Bitwarden clients.

## Quick Start
```bash
# Create docker-compose.yml with the content below
docker-compose up -d
```

## Docker Compose
```yaml
version: '3.8'

services:
  vaultwarden:

```

## Reverse Proxy (Traefik)
```yaml
labels:
  - "traefik.enable=true"
  - "traefik.http.routers.vaultwarden.rule=Host(`vault.yourdomain.com`)"
  - "traefik.http.routers.vaultwarden.tls=true"
  - "traefik.http.routers.vaultwarden.tls.certresolver=letsencrypt"
  - "traefik.http.services.vaultwarden.loadbalancer.server.port=8080"
  
  # WebSocket support
  - "traefik.http.routers.vaultwarden-websockets.rule=Host(`vault.yourdomain.com`) && PathPrefix(`/notifications/hub`)"
  - "traefik.http.routers.vaultwarden-websockets.entrypoints=websecure"
  - "traefik.http.services.vaultwarden-websockets.loadbalancer.server.port=3012"
```

## Backup Strategy
```bash
# Backup Vaultwarden data
docker run --rm -v vaultwarden-data:/data -v $(pwd):/backup alpine tar czf /backup/vaultwarden-backup.tar.gz -C /data .

# Backup PostgreSQL database
docker exec vaultwarden-postgres pg_dump -U vaultwarden vaultwarden > vaultwarden-db-backup.sql

# Restore database
docker exec -i vaultwarden-postgres psql -U vaultwarden vaultwarden < vaultwarden-db-backup.sql

# Restore Vaultwarden data
docker run --rm -v vaultwarden-data:/data -v $(pwd):/backup alpine tar xzf /backup/vaultwarden-backup.tar.gz -C /data

# Restart after restore
docker-compose restart vaultwarden
```

## Security Best Practices

### Production Setup
```yaml
environment:
  - SIGNUPS_ALLOWED=false
  - ADMIN_TOKEN=your-secure-admin-token
  - DOMAIN=https://vault.yourdomain.com
  - PASSWORD_ITERATIONS=100000
  - PBKDF2_MEMORY=64
  - PBKDF2_PARALLELISM=4
```

### SSL/TLS Configuration
```yaml
# Use HTTPS in production
environment:
  - DOMAIN=https://vault.yourdomain.com
  
# Configure proper certificates
# Traefik will handle Let's Encrypt automatically
```

### Access Control
```yaml
# Restrict admin access
environment:
  - ADMIN_TOKEN=your-secure-admin-token

# Network isolation
networks:
  vaultwarden-internal:
    driver: bridge
    internal: true
  vaultwarden-external:
    driver: bridge
```

## User Management

### Admin Panel Features
- **User management**: View and manage all users
- **Organization management**: Manage organizations
- **System diagnostics**: Check system health
- **Configuration**: Adjust settings
- **Audit logs**: View user activity

### Organization Setup
1. Create organization in admin panel
2. Invite users via email
3. Set up collections and groups
4. Configure access policies

### Emergency Access
```yaml
environment:
  - EMERGENCY_ACCESS_ALLOWED=true
```

## Performance Optimization
```yaml
# For better performance
environment:
  - DATABASE_MAX_CONNS=10
  - WEBSOCKET_ENABLED=true
  - WEBSOCKET_HEARTBEAT_INTERVAL=30

# Resource limits
deploy:
  resources:
    limits:
      memory: 512M
      cpus: '1.0'
    reservations:
      memory: 256M
      cpus: '0.5'
```

## Monitoring

### Health Checks
```bash
# Check if service is running
curl http://localhost:8080/alive

# Check admin panel
curl http://localhost:8080/admin/diagnostics
```

### Logs
```bash
# View logs
docker-compose logs -f vaultwarden

# Check for errors
docker-compose logs vaultwarden | grep ERROR
```

## Troubleshooting
- **Login issues**: Check domain configuration
- **Email problems**: Verify SMTP settings
- **Performance issues**: Monitor resource usage
- **Database errors**: Check PostgreSQL connection
- **WebSocket issues**: Verify reverse proxy configuration

## Migration from Bitwarden
1. **Export from Bitwarden**: Use Bitwarden export feature
2. **Import to Vaultwarden**: Use web vault import
3. **Update clients**: Point clients to new server URL
4. **Disable old account**: Cancel Bitwarden subscription

## API Usage
```bash
# Get user info
curl -H "Authorization: Bearer YOUR_TOKEN" \
  http://localhost:8080/api/accounts/profile

# Get organizations
curl -H "Authorization: Bearer YOUR_TOKEN" \
  http://localhost:8080/api/organizations

# Admin API
curl -H "Authorization: Bearer YOUR_ADMIN_TOKEN" \
  http://localhost:8080/api/users
```

## Maintenance
```bash
# Restart service
docker-compose restart vaultwarden

# Update image
docker-compose pull && docker-compose up -d

# Clean up old data
docker exec vaultwarden vaultwarden db cleanup

# Check database size
docker exec vaultwarden-postgres psql -U vaultwarden -c "SELECT pg_size_pretty(pg_database_size('vaultwarden'));"
```
