Registry - Polaris Integration

Description

This example demonstrates how to integrate Polaris service registry with GoFrame applications. It shows how to:

• Register services with Polaris
• Discover services using Polaris
• Implement service health checks
• Build distributed systems

Features

The example showcases the following features:

1. Service Registration

   • Automatic service registration
   • Health check configuration
   • Metadata management
   • Service routing
   • Rate limiting

2. Service Discovery

   • Dynamic service discovery
   • Load balancing
   • Failover support
   • Circuit breaking
   • Fault tolerance

3. Protocol Support

   • HTTP services
   • Custom protocols
   • Protocol extension

Requirements

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

Prerequisites

1. Running Polaris server:

   # Using docker
   docker run -d \
     --name polaris \
     -p 8090:8090 \
     -p 8091:8091 \
     -p 8093:8093 \
     -p 8761:8761 \
     polarismesh/polaris-server

Usage

1. Start the server:

   cd server
   go run server.go

2. Run the client:

   cd client
   go run client.go
