Go Web Application

Overview

The Go-Web-App is a web application built with Go that is forked from iam-veeramalla/go-web-app repo and further added DevOps/DevSecOps best practices by Uj5Ghare/Go-Web-App
This repository includes a GitHub Actions workflow & GitLab CI/CD pipeline to automate code quality checks, SonarQube analysis, application builds, Docker image vulnerability checks, deployment to EKS Cluster with Terraform, and monitoring with Zabbix & AWS CloudWatch.

Tools Used

• Programming Languages: Golang & HTML
• Cloud Platforms: AWS (EKS,EC2,VPC,IAM,S3)
• CI/CD Tools: GitHub Actions & GitLab CI/CD
• SCM Tools: Git, GitHub, GitLab
• Contaniration Platform: Docker
• Container Orchstrator: Kubernetes(EKS),
• K8s Package Manager: Helm
• Infrastructure As Code Tool: Terraform
• Process Management Tool: PM2
• Security Management Tools: SonarQube & Trivy
• Monitoring Tools: Zabbix & CloudWatch

Workflow

The GitHub Actions workflow consists of several jobs that run on different triggers, including pushes to main and dev branches, pull requests, and manual triggers.

Key Jobs

1. Code Quality Check

   • Runs golangci-lint to ensure code quality on push to main and dev branches.

2. SonarQube Analysis

   • Performs static code analysis using SonarQube for both production (main) and development (dev) branches.

3. Build Application

   • Builds the Go application for production and development branches, runs tests, and installs necessary packages (like PM2).

4. Image Vulnerability Checks

   • Scans Docker images for vulnerabilities using Trivy after building the application.

5. Push to Docker Hub

   • Pushes the built Docker image to Docker Hub with appropriate tags for production and development.

6. Update Helm Chart

   • Updates the Helm chart with the new image tag upon successful deployment to production.

Setup
