Build API with Golang, GORM and PostgreSQL (Dockerize)

Web Service with Go and Dockerize

This post will guide to build Dockerize Web Service with Go, Gin, GORM and PostgreSQL

Prerequisite:

1. Go (Gin)
2. GORM
3. Docker
4. PostgreSQL

Initialize Go App:

Make sure you have installed Docker on your machine. Then create new folder go_api and execute this command inside the go_api folder

// Init Golang Module
go mod init github.com/<YOUR_GITHUB_USERNAME>/go_api

// Get Package Gin and Gorm
go get -u github.com/gin-gonic/gin
go get -u gorm.io/gorm

Step 1 — Create API Check

This step will guide you to create new api to check if the web service run. First create new file inside root folder with name main.go and follow this code

package main

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

func main() {
 r := gin.Default()

 r.GET("/ping", func(c *gin.Context) {
  c.JSON(200, gin.H{
   "message": "pong",
  })
 })

 r.Run()
}

Save your file and try to run this web server using command go run main.go on your terminal and try hit localhost:8080/ping from your Browser or App…
