## Quick Start
### Using Docker Compose (Recommended)
1. Create a `docker-compose.yml` file:
```yaml
services:
api:
image: ghcr.io/davidfolch/apocapoc-api:latest
ports:
- "8080:8080"
environment:
- DB_PATH=/data/apocapoc.db
- PORT=8080
- APP_URL=http://localhost:8080
- JWT_SECRET=YOUR_SECRET_HERE
- JWT_EXPIRY=1h
- REFRESH_TOKEN_EXPIRY=7d
- DEFAULT_TIMEZONE=UTC
- REGISTRATION_MODE=open
# Email configuration (optional)
# - SMTP_HOST=smtp.example.com
# - SMTP_PORT=587
# - SMTP_USER=your-email@example.com
# - SMTP_PASSWORD=your-password
# - SMTP_FROM=noreply@example.com
# - SUPPORT_EMAIL=contact@apocapoc.app
# - SEND_WELCOME_EMAIL=false
volumes:
- habit-data:/data
restart: unless-stopped
volumes:
habit-data:
```
2. **Important**: Replace `YOUR_SECRET_HERE` with a secure random string for `JWT_SECRET`
3. Start the service:
```bash
docker-compose up -d
```
The API will be available at `http://localhost:8080`
**Available image tags:**
- `latest`: Latest stable release (recommended for production)
- `1`, `1.0`, `1.0.0`: Specific version tags
- `edge`: Latest development build from main branch (unstable)
- `sha-abc123`: Specific commit (for debugging)
**Configuration options:**
**Required:**
- `JWT_SECRET`: **Required**. Use a long random string
- `DB_PATH`: Database file path (default: `./data/apocapoc.db`)
**Application:**
- `PORT`: HTTP port (default: `8080`)
- `APP_URL`: Public URL for email links (e.g., `https://habits.yourdomain.com`)
- `DEFAULT_TIMEZONE`: Timezone for date calculations (e.g., `UTC`, `Europe/Madrid`)
**Authentication:**
- `JWT_EXPIRY`: Token expiration (e.g., `1h`, `24h`)
- `REFRESH_TOKEN_EXPIRY`: Refresh token expiration (e.g., `7d`, `168h`)
**Registration:**
- `REGISTRATION_MODE`: `open` (anyone can register) or `closed` (registration disabled)
**Email (optional - all or none):**
- `SMTP_HOST`: SMTP server hostname
- `SMTP_PORT`: SMTP port (`587` for STARTTLS, `465` for SSL)
- `SMTP_USER`: SMTP username
- `SMTP_PASSWORD`: SMTP password (use `$$` to escape `$` in passwords)
- `SMTP_FROM`: From address for emails
- `SUPPORT_EMAIL`: Support email shown in emails (default: `contact@apocapoc.app`)
- `SEND_WELCOME_EMAIL`: Send welcome email after verification (`true`/`false`)
**Note:** If SMTP is not configured, email verification is skipped and users are auto-verified.
