Registry - File Integration

Code Source: https://github.com/gogf/examples/tree/main/registry/file

Description

This example demonstrates how to use File-based service registry with GoFrame applications. It shows how to:

• Register services using file system
• Discover services from files
• Implement simple service discovery
• Build basic distributed systems

Structure

│   └── client.go      # Client implementation with file-based discovery
├── server/            # Server example

Features

The example showcases the following features:

1. Service Registration

   • File-based service registration
   • Simple metadata storage
   • Local file system integration
   • Automatic file management

2. Service Discovery

   • File-based service discovery
   • Local service lookup
   • Basic load balancing
   • Simple failover support

3. Protocol Support

   • HTTP services
   • Extensible for other protocols

Requirements

• Go 1.22 or higher
• Git
• GoFrame
• GoFrame File Registry

Prerequisites

No additional infrastructure required. The example uses the local file system for service registration and discovery.

Usage

1. Start the server:

   cd server
   go run server.go

2. Run the client:

   cd client
   go run client.go

Implementation Details

The example demonstrates:

1. File-based registry configuration
2. Service registration process
3. Service discovery mechanism
4. Basic health check implementation
5. Simple load balancing strategy

Notes

• Uses local file system
• Suitable for development and testing
• Simple to set up and use
• No external dependencies
• File-based persistence
• Basic service discovery
• Limited scalability
• Consider security in production
• Handle file permissions properly
• Implement proper error handling
• Monitor file system usage
• Clean up old registrations
