### 🔌 Backend Service Architecture
#### Core Modules
1. **Configuration Management** (`utils/garage.go`)
- Automatically reads the Garage configuration file (`garage.toml`)
- Extracts admin API endpoints, authentication information, etc.
- Supports overriding configuration with environment variables
2. **API Proxy** (`router/`)
- Proxies frontend requests to the Garage Admin API
- Handles authentication and error translation
- Provides a unified RESTful interface
3. **Session Management** (`utils/session.go`)
- Supports user authentication (optional)
- Session state management
4. **Caching Mechanism** (`utils/cache.go`)
- Caches API responses
- Reduces request pressure on the Garage cluster
## Deployment Scenarios
### 🐳 Docker Deployment (Recommended)
#### 1. Deploying with a Garage Cluster
```yaml
services:
garage:
image: dxflrs/garage:v1.0.1
volumes:
- ./garage.toml:/etc/garage.toml
- ./meta:/var/lib/garage/meta
- ./data:/var/lib/garage/data
ports:
- 3900:3900 # S3 API
- 3901:3901 # RPC
- 3902:3902 # S3 Web
- 3903:3903 # Admin API
webui:
image: adekabang/garage-webui:latest
volumes:
- ./garage.toml:/etc/garage.toml:ro
ports:
- 3909:3909
environment:
API_BASE_URL: "http://garage:3903"
S3_ENDPOINT_URL: "http://garage:3900"
```
#### 2. Standalone Deployment
```bash
docker run -p 3909:3909 \
-v ./garage.toml:/etc/garage.toml:ro \
-e API_BASE_URL="http://garage-host:3903" \
-e API_ADMIN_KEY="your-admin-token" \
adekabang/garage-webui:latest
```
### 🖥️ Binary Deployment
```bash
# Download the binary file
wget -O garage-webui https://github.com/Adekabang/garage-webui/releases/download/1.0.9/garage-webui-v1.0.9-linux-amd64
chmod +x garage-webui
# Run the service
CONFIG_PATH=./garage.toml ./garage-webui
```
### 🔧 SystemD Service
```ini
[Unit]
Description=Garage Web UI
After=network.target
[Service]
Environment="PORT=3909"
Environment="CONFIG_PATH=/etc/garage.toml"
ExecStart=/usr/local/bin/garage-webui
Restart=always
[Install]
WantedBy=default.target
```
## Configuration Management
### 📝 Garage Configuration Requirements
The Web UI requires the Garage cluster to have the Admin API enabled:
```toml
# garage.toml
[admin]
api_bind_addr = "[::]:3903"
admin_token = "your-secure-admin-token"
metrics_token = "your-metrics-token" # Optional
```
### 🌍 Environment Variable Configuration
| Variable Name | Description | Default Value |
| ----------------- | ----------------------------- | -------------------- |
| `CONFIG_PATH` | Path to Garage config file | `/etc/garage.toml` |
| `API_BASE_URL` | Garage Admin API address | Read from config file|
| `API_ADMIN_KEY` | Admin API token | Read from config file|
| `S3_ENDPOINT_URL` | S3 API address | Read from config file|
| `S3_REGION` | S3 region | `garage` |
| `BASE_PATH` | Web UI base path | `/` |
| `PORT` | Service port | `3909` |
| `HOST` | Binding address | `0.0.0.0` |
### 🔐 Authentication Configuration
#### Enable Web UI Authentication
```bash
# Generate password hash
htpasswd -nbBC 10 "admin" "password"
# Set environment variable
AUTH_USER_PASS="admin:$2y$10$DSTi9o..."
```
## Management Best Practices
### 🚀 Daily Operations
#### 1. Cluster Health Monitoring
- **Regular Checks**: Monitor cluster status via the home dashboard
- **Alerting Setup**: Configure monitoring systems to connect to the `/metrics` endpoint
- **Performance Observation**: Pay attention to storage node connection status and partition health
#### 2. Bucket Management
- **Naming Conventions**: Establish uniform bucket naming conventions
- **Minimize Permissions**: Assign the minimum necessary permissions to access keys
- **Quota Management**: Set appropriate quota limits for important services
#### 3. Access Control
- **Regular Rotation**: Rotate API access keys periodically
- **Permission Audits**: Regularly review bucket permission assignments
- **Key Management**: Create dedicated access keys for different purposes
### 🔧 Troubleshooting
#### 1. Connection Issues
```bash
# Check Admin API accessibility
curl -H "Authorization: Bearer YOUR_TOKEN" \
http://garage-host:3903/v2/GetClusterHealth
# Check network connectivity
telnet garage-host 3903
```
#### 2. Configuration Issues
- Verify the correctness of the `garage.toml` configuration
- Confirm that the Admin API port is open
- Check firewall and network policies
#### 3. Performance Optimization
- Enable caching to reduce API calls
- Use a reverse proxy (like Nginx) for SSL termination
- Monitor resource usage
### 📊 Monitoring Integration
#### Prometheus Metrics
The Web UI can be configured to monitor Garage's Prometheus metrics:
```yaml
# prometheus.yml
scrape_configs:
- job_name: "garage"
static_configs:
- targets: ["garage-host:3903"]
metrics_path: /metrics
bearer_token: "your-metrics-token"
```
#### Key Metrics
- `garage_cluster_health`: Cluster health status
- `garage_storage_usage`: Storage usage
- `garage_api_requests`: API request statistics
- `garage_replication_status`: Data replication status
## Development Guide
### 🛠️ Development Environment Setup
```bash
# Clone the project
git clone https://github.com/Adekabang/garage-webui.git
cd garage-webui
# Install frontend dependencies
pnpm install
# Install backend dependencies
cd backend && go mod download && cd ..
# Start the development server
pnpm run dev
```
### 🔧 Technology Choices
- **Frontend**: React 18 + TypeScript + Tailwind CSS
- **State Management**: React Query (TanStack Query)
- **Routing**: React Router
- **UI Components**: Custom component library
- **Backend**: Go + Gin framework
- **Configuration Parsing**: go-toml
### 📋 Contribution Guidelines
1. **Coding Standards**: Follow the project's ESLint and Go fmt standards
2. **Testing**: New features require corresponding tests
3. **Documentation**: Update relevant documents and API descriptions
4. **Compatibility**: Ensure compatibility with the latest version of Garage
## Security Considerations
### 🔒 Security Recommendations
1. **Network Security**
- Use HTTPS in production environments
- Restrict network access to the Admin API
- Use firewall rules to protect sensitive ports
2. **Authentication Security**
- Consider integrating with an enterprise identity authentication system
3. **Permission Control**
- Follow the principle of least privilege
- Use a dedicated administrator token
