# SeaweedFS Admin Component
A modern web-based administration interface for SeaweedFS clusters built with Go, Gin, Templ, and Bootstrap.
## Features
- **Dashboard**: Real-time cluster status and metrics
- **Master Management**: Monitor master nodes and leadership status
- **Volume Server Management**: View volume servers, capacity, and health
- **Object Store Bucket Management**: Create, delete, and manage Object Store buckets with web interface
- **System Health**: Overall cluster health monitoring
- **Responsive Design**: Bootstrap-based UI that works on all devices
- **Authentication**: Optional user authentication with sessions
- **TLS Support**: HTTPS support for production deployments
## Building
### Using the Admin Makefile
The admin component has its own Makefile for development and building:
```bash
# Navigate to admin directory
cd weed/admin
# View all available targets
make help
# Generate templates and build
make build
# Development mode with template watching
make dev
# Run the admin server
make run
# Clean build artifacts
make clean
```
### Using the Root Makefile
The root SeaweedFS Makefile automatically integrates the admin component:
```bash
# From the root directory
make install # Builds weed with admin component
make full_install # Full build with all tags
make test # Runs tests including admin component
# Admin-specific targets from root
make admin-generate # Generate admin templates
make admin-build # Build admin component
make admin-run # Run admin server
make admin-dev # Development mode
make admin-clean # Clean admin artifacts
```
### Manual Building
If you prefer to build manually:
```bash
# Install templ compiler
go install github.com/a-h/templ/cmd/templ@latest
# Generate templates
templ generate
# Build the main weed binary
cd ../../../
go build -o weed ./weed
```
## Development
### Template Development
The admin interface uses [Templ](https://templ.guide/) for type-safe HTML templates:
```bash
# Watch for template changes and auto-regenerate
make watch
# Or manually generate templates
make generate
# Format templates
make fmt
```

### S3 Bucket Management
The admin interface includes comprehensive Object Store bucket management capabilities. See [S3_BUCKETS.md](S3_BUCKETS.md) for detailed documentation on:
- Creating and deleting Object Store buckets
- Viewing bucket contents and metadata
- Managing bucket permissions and settings
- API endpoints for programmatic access
## Usage
### Basic Usage
```bash
# Start admin interface on default port (23646)
weed admin
# Start with custom configuration
weed admin -port=8080 -masters="master1:9333,master2:9333"
# Start with authentication
weed admin -adminUser=admin -adminPassword=secret123
# Start with HTTPS
weed admin -port=443 -tlsCert=/path/to/cert.pem -tlsKey=/path/to/key.pem
```
### Configuration Options
| Option | Default | Description |
|--------|---------|-------------|
| `-port` | 23646 | Admin server port |
| `-masters` | localhost:9333 | Comma-separated master servers |
| `-adminUser` | admin | Admin username (if auth enabled) |
| `-adminPassword` | "" | Admin password (empty = no auth) |
| `-tlsCert` | "" | Path to TLS certificate |
| `-tlsKey` | "" | Path to TLS private key |
### Docker Usage
```bash
# Build Docker image with admin component
make docker-build
# Run with Docker
docker run -p 23646:23646 seaweedfs/seaweedfs:latest admin -masters=host.docker.internal:9333
```
## Development Workflow
### Quick Start
```bash
# Clone and setup
git clone <seaweedfs-repo>
cd seaweedfs/weed/admin
# Install dependencies and build
make install-deps
make build
# Start development server
make dev
```
### Making Changes
1. **Template Changes**: Edit `.templ` files in `view/`
- Templates auto-regenerate in development mode
- Use `make generate` to manually regenerate
2. **Go Code Changes**: Edit `.go` files
- Restart the server to see changes
- Use `make build` to rebuild
3. **Static Assets**: Edit files in `static/`
- Changes are served immediately
### Testing
```bash
# Run admin component tests
make test
# Run from root directory
make admin-test
# Lint code
make lint
# Format code
make fmt
```
## Production Deployment
### Security Considerations
1. **Authentication**: Always set `adminPassword` in production
2. **HTTPS**: Use TLS certificates for encrypted connections
3. **Firewall**: Restrict admin interface access to authorized networks
### Example Production Setup
```bash
# Production deployment with security
weed admin \
-port=443 \
-masters="master1:9333,master2:9333,master3:9333" \
-adminUser=admin \
-adminPassword=your-secure-password \
-tlsCert=/etc/ssl/certs/admin.crt \
-tlsKey=/etc/ssl/private/admin.key
```
### Monitoring
The admin interface provides endpoints for monitoring:
- `GET /health` - Health check endpoint
- `GET /metrics` - Prometheus metrics (if enabled)
- `GET /api/status` - JSON status information
## Troubleshooting
### Common Issues
1. **Templates not found**: Run `make generate` to create template files
2. **Build errors**: Ensure `templ` is installed with `make install-templ`
3. **Static files not loading**: Check that `static/` directory exists and has proper files
4. **Connection errors**: Verify master and filer addresses are correct
### Debug Mode
```bash
# Enable debug logging
weed -v=2 admin
# Check generated templates
ls -la view/app/*_templ.go view/layout/*_templ.go
```

## Architecture
The admin component follows a clean architecture:
- **Presentation Layer**: Templ templates + Bootstrap CSS
- **HTTP Layer**: Gin router with middleware
- **Business Logic**: Handler functions in `dash/` package
- **Data Layer**: Communicates with SeaweedFS masters and filers
This separation makes the code maintainable and testable.
