CI/CD Improvements Summary

🎯 Overview

This document summarizes the additional CI/CD improvements added to enhance the build, test, and deployment pipeline for the IRCTC monolith project.

Date: November 2025

📋 New Workflows Added

1. ✅ Code Quality & Security Workflow

File: .github/workflows/code-quality.yml

Purpose:

  • Automated code quality checks
  • Security vulnerability scanning
  • Test coverage reporting
  • Code style validation

Triggers:

  • Pull requests to main or develop
  • Pushes to main or develop branches
  • Manual workflow dispatch

Features:

  • ✅ Test execution with coverage generation (Jacoco)
  • ✅ Code style checking (Checkstyle)
  • ✅ Static code analysis (SpotBugs)
  • ✅ OWASP Dependency Check for security vulnerabilities
  • ✅ Test result and coverage report archiving
  • ✅ Codecov integration (optional)

Benefits:

  • Early detection of code quality issues
  • Security vulnerability identification
  • Test coverage visibility
  • Automated quality gates

2. ✅ Build Status Monitor

File: .github/workflows/build-status.yml

Purpose:

  • Monitor build health across all workflows
  • Generate build status reports
  • Track workflow execution history

Triggers:

  • Completion of other workflows (Maven Package, Jenkins Trigger, Code Quality)
  • Daily schedule (midnight UTC)
  • Manual workflow dispatch

Features:

  • ✅ Automatic monitoring of workflow runs
  • ✅ Build status reporting
  • ✅ Workflow execution history
  • ✅ Health check notifications

Benefits:

  • Centralized build status visibility
  • Proactive monitoring
  • Historical build tracking

3. ✅ Docker Build Workflow

File: .github/workflows/docker-build.yml

Purpose:

  • Build Docker images from the application
  • Push images to GitHub Container Registry
  • Support for multi-architecture builds

Triggers:

  • Push to main or develop branches
  • Tag creation (v*)
  • Pull requests (build only, no push)
  • Manual workflow dispatch with push option

Features:

  • ✅ Docker Buildx for advanced builds
  • ✅ GitHub Container Registry (ghcr.io) integration
  • ✅ Automatic tagging (branch, PR, semver, SHA)
  • ✅ Build caching for faster builds
  • ✅ Conditional image pushing
  • ✅ Multi-architecture support ready

Benefits:

Swagger Docs Push/Release Documentation ✅ Active

🚀 Integration Points

GitHub Actions → Jenkins

  • Trigger: Automatic on push/PR
  • Purpose: CI/CD pipeline execution
  • Status: ✅ Configured and working

Code Quality → Pull Requests

  • Trigger: On PR creation/updates
  • Purpose: Quality gates before merge
  • Status: ✅ Ready to use

Docker → Container Registry

  • Trigger: On push to main/develop or tag creation
  • Purpose: Container image distribution
  • Status: ✅ Ready (requires Dockerfile)

📝 Configuration Requirements

Required Secrets

GitHub Secrets (Optional)

  • CODECOV_TOKEN - For code coverage reporting (optional)
  • JENKINS_URL - Jenkins server URL (already configured)
  • JENKINS_USER - Jenkins username (already configured)
  • JENKINS_TOKEN - Jenkins API token (already configured)

Required Files

Dockerfile (For Docker Build)

Create a Dockerfile in repository root to enable Docker builds:

FROM eclipse-temurin:21-jre-alpine
WORKDIR /app
COPY target/*.jar app.jar
EXPOSE 8082
ENTRYPOINT ["java", "-jar", "app.jar"]

Maven Plugins (Optional but Recommended)

Add to pom.xml for enhanced quality checks:

<!-- Jacoco for code coverage -->
<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.8.11</version>
</plugin>

<!-- Checkstyle for code style -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-checkstyle-plugin</artifactId>
    <version>3.3.1</version>
</plugin>

<!-- SpotBugs for static analysis -->
<plugin>
    <groupId>com.github.spotbugs</groupId>
    <artifactId>spotbugs-maven-plugin</artifactId>
    <version>4.8.2.2</version>
</plugin>
