Deploy Go in AWS Beanstalk

Follow the steps here to walk you through the process of deploying a Go application to Elastic Beanstalk

Step 1: Create Go project

Create Go project with application.go:

package main

import (
    "encoding/json"
    "log"
    "net/http"
    "os"
)

func main() {
    port := os.Getenv("PORT")
    if port == "" {
        port = "5000"
    }
    
    f, _ := os.Create("/var/log/golang/golang-server.log")
    defer f.Close()
    log.SetOutput(f)
    
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request){
        w.Header().Set("Content-Type", "application/json")
        w.Write([]byte("hello golang 123"))
    })
    
    http.ListenAndServe(":"+port, nil)
}

Test Go locally with command

go run application.go

To view the sample application, type the following URL into your web browser. http://localhost:5000/

After testing your application, you are ready to deploy it to Elastic Beanstalk.

zip ../goexample.zip -r * .[^.]*
