Create a Go(Gin) environment with Docker

at first

We will assume that you already have a Docker environment. Let’s easily create a Go (Gin) environment using Docker.

Create DockerFile

Create a working directory, create [DockerFile] and copy and paste the following

// specify the base Docker image
FROM golang:latest

create a working directory inside the container

RUN mkdir /go/src/work

specify the directory when logging into the container

WORKDIR /go/src/work

Launch GoApp

CMD ["go","run","main.go"]

migrate host files to container working directory

ADD . /go/src/work

create docker-compose.yml

Create a [docker-compose.yml] file in the same directory and copy and paste the following

version: '3' # specify the version of the compose file
app: # service name
build: . # Specify the directory where the Dockerfile used for building is located
tty: true # Container startup persistence
volumes: - .:/go/src/work # Specify mount directory
ports: -8080:8080

Create Go source

Create a [main.go] file in the same directory and copy and paste the following

package main

import (

func helloHandler(w http.ResponseWriter, r *http.Request) {
  fmt.Fprintf(w, "<h1>Hello, World</h1>")

func main() {
  http. HandleFunc("/", helloHandler)
  fmt.Println("Server Start")
  http.ListenAndServe(":8080", nil)

Check if the file exists in the directory by hitting the ls command.

ls DockerFile docker-compose.yml main.go

Command execution with CLI

Hit the following command with git bush (CLI tool).

$ docker-compose build
$ docker-compose up -d

Try visiting http://localhost:8080.
