Mar 17, 2025

Lecture Notes: CICD Setup and Integration

Key Topics Discussed

  • CICD Setup and Transition

    • Transition from G to build tool
    • Focused on using Marvin (B2)
    • Integration with automation servers like Jenkins

  • Source Code Management

    • Code is pushed to GitHub
    • Build tool integrates with GitHub

  • Build Process and Testing

    • Use of JUnit for unit testing
    • Ensures code functionalities integrate
    • Demo of JUnit's role in code testing

  • Code Analysis

    • Tools discussed: SonarQube
    • Analyzes vulnerabilities, code smells, bugs
    • Developers receive feedback via SonarQube UI

  • Integration with Jenkins

    • Jenkins communicates with SonarQube
    • Quality gates and profiles in SonarQube

  • Quality Gates and Profiles

    • Ensure code adheres to organizational standards
    • Quality gates evaluate code during builds

  • Artifact Deployment and Management

    • Use of Nexus for storing artifacts
    • Importance of Software Bill of Materials (SBOM)

  • Deployment Process

    • Jenkins pipeline manages build, test, and deployment stages
    • Artifacts are pushed to Nexus, then deployed to a web server

  • Continuous Delivery (CD) and Deployment

    • CD starts after artifacts are ready in Nexus
    • Continuous Delivery vs. Continuous Deployment

  • Pipeline Overview

    • Concept of a pipeline as a flow from code writing to deployment
    • Incorporates building, testing, and deploying code

  • Monitoring and Logging Tools

    • Mention of tools like DataDog and Splunk
    • Used for monitoring production environments

  • Code Quality and Testing

    • Unit testing vs. code analysis
    • Importance of testing code before deployment
    • Use of JUnit as a testing framework

Tools and Configuration

  • Jenkins Configuration

    • Setting up Jenkins server
    • Integration with SonarQube and Nexus

  • SonarQube Configuration

    • Creating quality gates and profiles
    • Webhooks to notify Jenkins of analysis results

  • Nexus Configuration

    • Managing artifacts in repositories
    • Differentiating snapshot and release repositories

  • Tomcat Server

    • Configured for deployment of artifacts
    • User roles and access setup in tomcat-users.xml

Troubleshooting and Tips

  • Troubleshooting Jenkins and SonarQube Integration

    • Handling credential issues
    • Ensuring correct URL configurations

  • Common Errors

    • Deployment failures due to incorrect configuration
    • Importance of updating versions for releases

  • Best Practices

    • Maintain multiple artifact versions for rollback
    • Use of testing frameworks to ensure code quality

Conclusion

The lecture covered the setup and integration of a CICD pipeline using Jenkins, SonarQube, and Nexus. Students were guided through setting up their environments, integrating various tools, and understanding the importance of testing and code quality analysis in a continuous integration and continuous delivery (CI/CD) setup. The session also emphasized the need for proper configuration and troubleshooting skills.
