How to deploy and manage the Golang microservices framework

How to deploy and manage Golang microservice framework to build microservices: Create a Go project and use mockgen to generate a basic service template. Deploy microservices: Deploy using specific commands depending on the platform (such as Kubernetes or Docker). Manage microservices: monitoring (Prometheus, Grafana), logging (Jaeger, Zipkin), failover (Istio, Envoy).

How to deploy and manage the Golang microservice framework

With the popularity of microservice architecture, Go has become a Ideal for microservices. This article will introduce how to use Golang to build, deploy and manage a microservices framework.

Building Microservices

First, we need to create a Golang project that contains our microservice code. The following command can be used:

go mod init my-microservice

Next, we can generate a basic service template using the following command:

go run github.com/golang/mock/mockgen -destination=./mock -package=mypackage github.com/example/project Interface Interface

Deploy microservices

The deployment process varies depending on the platform used . Here are some examples of deployments using common platforms:

Kubernetes:

kubectl apply -f my-microservice.yaml

Docker:

docker build -t my-microservice .
docker run -p 8080:8080 my-microservice

Management Micro Service

Managing microservices requires monitoring, logging, and failover measures. Here are some recommended tools:

Monitoring:

• Prometheus
• Grafana

Log:

• Jaeger
• Zipkin

Failover:

• Istio
• Envoy

Practical Case

The following is a practical case using Gin and GORM to build and deploy a simple API service:

package main

import (
    "github.com/gin-gonic/gin"
    "gorm.io/gorm"
)

type User struct {
    ID        uint   `gorm:"primarykey"`
    FirstName string `gorm:"size:255;not null"`
    LastName  string `gorm:"size:255;not null"`
}

func main() {
    // 创建 Gin 路由器
    r := gin.Default()
    db := connectToDB()

    r.GET("/users", func(c *gin.Context) {
        var users []User
        db.Find(&users)
        c.JSON(200, users)
    })

    // 启动服务器
    r.Run(":8080")
}
