Registry

The registry is responsible for service discovery in Go Micro. It allows services to register themselves and discover other services.

Features

• Service registration and deregistration
• Service lookup
• Watch for changes

Implementations

Go Micro supports multiple registry backends, including:

• MDNS (default)
• Consul
• Etcd
• NATS

You can configure the registry when initializing your service.

Example Usage

Here's how to use a custom registry (e.g., Consul) in your Go Micro service:

package main

import (
    "go-micro.dev/v5"
    "go-micro.dev/v5/registry/consul"
)

func main() {
    reg := consul.NewRegistry()
    service := micro.NewService(
        micro.Registry(reg),
    )
    service.Init()
    service.Run()
}
