Introduction to Heroku Cloud
Heroku is a popular platform-as-a-service (PaaS) that allows developers to deploy and run applications on the cloud. It supports multiple programming languages, including Go, making it easy for developers to build and deploy their Go applications. In this article, we will discuss how to use Heroku to deploy Golang application.
Step-by-step Guide to Use Heroku to Deploy Golang Application
To deploy Go app on Heroku cloud platform, follow the steps mentioned below. Before you begin, here are the pre-requirements that you must consider for deploying your app on Heroku Golang.
Prerequisites before using Heroku to deploy Go apps.
- Basic knowledge of Golang and Git.
- Install git in your system if not already installed because Heroku will depend on it for deployment.
- If your project is unavailable in Git, then commit your application changes in git.
Step 1: Set Up a Go Development Environment
To get started with Golang deployment, you need to set up a Go development environment on your local machine. You can download and install Go from the official website.
Step 2: Initialize a Go Module
Go Modules is a package management system for Go that provides versioning and dependency management. By using Go Modules, developers can easily manage their dependencies and ensure that their applications run smoothly on different systems, without the need to set up a GOPATH environment variable.
To create a Go application with Go Modules, you need to initialize a new Go Modules project. You can do this by running the following command in the terminal:
go mod init <module-name>
Step 3: Create a Basic Golang Application
Next, you can create a simple Go application, such as a basic Hello World program. The code for this program is as follows:
package main
import (
"fmt"
"net/http"
)
func main() {
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
fmt.Fprintln(w, "Hello World!")
})
http.ListenAndServe(":8080", nil)
}
Now comes the essential part of Golang hosting.

Step 4: Create a Heroku Account
To deploy your application on Heroku, you need to create a Heroku account. Sign-up for a free account on the official website.
Step 5: Verify Heroku Account
To verify your Heroku account, you can follow these steps:
1. Log in to your Heroku account.
2. Go to the “Account Settings” page.
3. Click on the “Verify Account” button.
4. Follow the steps to provide and verify your personal information, including your full name, address, and phone number.
5. Provide payment information to verify your account, which can be a credit card or PayPal account.
Step 6: Install the Heroku CLI
The Heroku CLI (Command Line Interface) allows you to manage and deploy your applications from the terminal. To install the Heroku CLI, follow the instructions below
1. Go to the Heroku CLI download page: Heroku CLI.
2. Select your operating system (Windows, MacOS, or Linux) and follow the instructions to download and install the Heroku CLI.
3. Open a terminal or command prompt window & type the command:
heroku login
4. Enter your Heroku credentials to log in.
Step 7: Create a New Heroku Application
To create a new Heroku application, run the following command in the terminal:
heroku create
Step 8: Deploy Golang App on Heroku
To use Heroku to deploy Golang web app, you need to create a Procfile file that specifies the command to run the application. The contents of the Procfile file should be as follows:
web: go run main.go
Next, add the files in your Go application to a Git repository and push the repository to Heroku using the following commands:
git init git add . git commit -m "Initial commit" git push heroku master
Step 9: Launch the Application
After the application is successfully deployed, you can launch it by running the following command:
heroku open
The Go application was deployed to Heroku and opened using the heroku open command. The application’s output, “Hello, World!” is displayed in a web browser. The URL of the application on Heroku is also shown in the web browser’s address bar.
You are successful with Heroku Golang now. With your Go application now running on Heroku, you would now better understand how to deploy Golang web application. You can access it through the URL in the terminal as an output of the above heroku open command.
