# Docker Reference
This page documents the Docker Compose configuration for Reflector. For the complete deployment guide, see [Deployment Guide](./overview).
## Services
The `docker-compose.prod.yml` includes these services:
| Service | Image | Purpose |
|---------|-------|---------|
| `web` | `monadicalsas/reflector-frontend` | Next.js frontend |
| `server` | `monadicalsas/reflector-backend` | FastAPI backend |
| `worker` | `monadicalsas/reflector-backend` | Celery worker for background tasks |
| `beat` | `monadicalsas/reflector-backend` | Celery beat scheduler |
| `redis` | `redis:7.2-alpine` | Message broker and cache |
| `postgres` | `postgres:17-alpine` | Primary database |
| `caddy` | `caddy:2-alpine` | Reverse proxy with auto-SSL |
## Environment Files
Reflector uses two separate environment files:
### Backend (`server/.env`)
Used by: `server`, `worker`, `beat`
Key variables:
```env
# Database connection
DATABASE_URL=postgresql+asyncpg://reflector:reflector@postgres:5432/reflector
# Redis
REDIS_HOST=redis
CELERY_BROKER_URL=redis://redis:6379/1
CELERY_RESULT_BACKEND=redis://redis:6379/1
# API domain and CORS
BASE_URL=https://api.example.com
CORS_ORIGIN=https://app.example.com
# Modal GPU processing
TRANSCRIPT_BACKEND=modal
TRANSCRIPT_URL=https://...
TRANSCRIPT_MODAL_API_KEY=...
```
### Frontend (`www/.env`)
Used by: `web`
Key variables:
```env
# Domain configuration
SITE_URL=https://app.example.com
API_URL=https://api.example.com
WEBSOCKET_URL=wss://api.example.com
SERVER_API_URL=http://server:1250
# Authentication
NEXTAUTH_URL=https://app.example.com
NEXTAUTH_SECRET=...
```
Note: `API_URL` is used client-side (browser), `SERVER_API_URL` is used server-side (SSR).
## Volumes
| Volume | Purpose |
|--------|---------|
| `redis_data` | Redis persistence |
| `postgres_data` | PostgreSQL data |
| `server_data` | Uploaded files, local storage |
| `caddy_data` | SSL certificates |
| `caddy_config` | Caddy configuration |
## Network
All services share the default network. The network is marked `attachable: true` to allow external containers (like Authentik) to join.
## Common Commands
### Start all services
```bash
docker compose -f docker-compose.prod.yml up -d
```
### View logs
```bash
# All services
docker compose -f docker-compose.prod.yml logs -f
# Specific service
docker compose -f docker-compose.prod.yml logs server --tail 50
```
### Restart a service
```bash
# Quick restart (doesn't reload .env changes)
docker compose -f docker-compose.prod.yml restart server
# Reload .env and restart
docker compose -f docker-compose.prod.yml up -d server
```
### Run database migrations
```bash
docker compose -f docker-compose.prod.yml exec server uv run alembic upgrade head
```
### Access database
```bash
docker compose -f docker-compose.prod.yml exec postgres psql -U reflector
```
### Pull latest images
```bash
docker compose -f docker-compose.prod.yml pull
docker compose -f docker-compose.prod.yml up -d
```
### Stop all services
```bash
docker compose -f docker-compose.prod.yml down
```
### Full reset (WARNING: deletes data)
```bash
docker compose -f docker-compose.prod.yml down -v
```
## Customization
### Using a different database
To use an external PostgreSQL:
1. Remove `postgres` service from compose file
2. Update `DATABASE_URL` in `server/.env`:
```env
DATABASE_URL=postgresql+asyncpg://user:pass@external-host:5432/reflector
```
### Using external Redis
1. Remove `redis` service from compose file
2. Update Redis settings in `server/.env`:
```env
REDIS_HOST=external-redis-host
CELERY_BROKER_URL=redis://external-redis-host:6379/1
```
### Adding Authentik
To add Authentik for authentication, see [Authentication Setup](./auth-setup). Quick steps:
1. Deploy Authentik separately
2. Connect to Reflector's network:
```bash
docker network connect reflector_default authentik-server-1
```
3. Add to Caddyfile:
```
authentik.example.com {
reverse_proxy authentik-server-1:9000
}
```
## Caddyfile Reference
The Caddyfile supports environment variable substitution:
```
{$FRONTEND_DOMAIN:app.example.com} {
reverse_proxy web:3000
}
{$API_DOMAIN:api.example.com} {
reverse_proxy server:1250
}
```
Set `FRONTEND_DOMAIN` and `API_DOMAIN` environment variables, or edit the file directly.
### Reload Caddy after changes
```bash
docker compose -f docker-compose.prod.yml exec caddy caddy reload --config /etc/caddy/Caddyfile
```
