3 Exciting Go-lang Projects to Kickstart Your DevOps Journey

💡 Introduction

Welcome to the world of DevOps! 🚀 Today, I’m back with another exciting blog to help you dive deeper into practical programming for DevOps tasks. In my previous blog, we explored 3 Python projects that laid the foundation for DevOps automation.

Now, let’s switch gears and explore the power of Go-lang! This blog will guide you through building 3 Go-lang projects that are both practical and beginner-friendly:

• A Monitor Disk Usage tool for tracking storage stats.


• Hosting a resume website using an HTTP server.


• A RESTful API program to manage DevOps tools.

So, grab your favorite code editor, and let’s get started! 🎉

💡 Pre-Requisites

Before we dive into building these projects, let’s make sure your environment is set up and ready to go. Here’s what you need:

1. Go (Golang)

You’ll need to have Go installed on your system. Follow these steps based on your operating system:

Windows

• Download the latest Go installer from the official website.


• Run the installer and follow the on-screen instructions.


• Verify the installation by opening Command Prompt or PowerShell and typing:
  

go version

Ubuntu

• Open a terminal and run:
  

sudo apt update  

sudo apt install -y golang

• Verify the installation:
  

go version

macOS

• Use Homebrew to install Go. Run:
  

brew install go

• Verify the installation:
  

go version

2. Basic Understanding of Go

While you don’t need to be an expert, having a fundamental understanding of Go concepts like variables, functions, and structs will help you follow along smoothly. If you’re new to Go, I recommend exploring the Go Tour for a quick introduction.

With these prerequisites met, you’re all set to start building these awesome Go-lang projects! 🚀

💡 Monitor Disk Usage App

Let’s kick off our journey with the first project — a disk usage monitoring tool. This program will help you analyze disk usage for any specified directory on your system.

You can find the source code in my

Since I have a single partition, I will get the same result if I provide different paths.

This project demonstrates how Go can interact with your system’s underlying APIs, making it a great starting point for system monitoring tasks. 🎉

💡 HTTP Server Program: Hosting a Portfolio Website

The second project involves creating an HTTP server in Go that hosts a portfolio website. This project demonstrates how you can build and serve static websites while incorporating a health check endpoint for monitoring.

You can find the source code in my

This project showcases how to use Go-lang to create a functional web server for hosting static content, with additional monitoring through a health check endpoint. 🎉

💡 RESTful API Project: Managing DevOps Tools

In the final project of this blog, we’ll create a RESTful API that allows you to manage a list of DevOps tools. This program demonstrates the use of Go’s net/http package to handle RESTful routes and manage data.

The complete source code is available on my

1. Add a New Tool
   To add a new tool, use:
   

curl -X POST -H "Content-Type: application/json" \

-d '{"name":"Prometheus","description":"A monitoring system and time-series database.","category":"Monitoring"}' \

💡 Conclusion

In this blog, we’ve explored three practical Go projects that help you get hands-on experience with different aspects of software development. From monitoring disk usage to building a simple HTTP server to hosting a portfolio website, and finally, creating a RESTful API to manage DevOps tools, these projects provide a solid foundation for anyone looking to sharpen their Go programming skills.

• The disk usage monitoring application introduced you to system calls and basic file handling in Go, giving you insight into how you can interact with a machine’s file system.


• The HTTP server project allowed you to learn how to serve static files and handle basic health-check endpoints, helping you get started with web development in Go.


• The RESTful API project demonstrated how to structure an API, manage data with concurrency control, and make your application interactive through POST and GET requests.

Each of these projects is a building block that can be expanded upon to suit real-world applications. Whether you are interested in monitoring systems, developing web applications, or building APIs, Go provides the simplicity and power needed for efficient development.
