Day 70 : CI Pipeline for VProfile

Today, I explored how a Continuous Integration (CI) pipeline works for my VProfile project. CI ensures that code changes are automatically tested, analyzed, and packaged before being deployed. This helps teams detect errors early and deliver software faster.

🔄 Flow of CI Pipeline

Here’s how the CI process flows step by step (as shown in the diagram above):

1. Developer (Git Commit)

   • A developer commits code to GitHub.

   • This triggers Jenkins to start the pipeline.

2. Fetch Code (Git Plugin)

   • Jenkins fetches the latest code from the repository.

3. Build (Maven Plugin)

   • Jenkins uses Maven to build the project.

   • Dependencies are resolved, and the application is packaged.

4. Unit Testing (Maven + JUnit)

   • Automated unit tests run to verify code functionality.

   • If tests fail, the pipeline stops here.

5. Code Quality Check (SonarQube Plugin)

   • Code is analyzed by SonarQube for quality, security vulnerabilities, and code smells.

   • The quality gate must pass for the pipeline to continue.

6. Artifact Upload (Nexus OSS)

   • Once the build is successful, the artifact (WAR/JAR file) is uploaded to Nexus Repository.

   • This artifact can later be used for deployment in test or production environments.

⚡ Why This Matters

• Automation reduces manual errors.

• Early bug detection via unit tests and SonarQube analysis.

• Versioned artifacts stored in Nexus ensure repeatable deployments.

• Developer productivity increases with fast feedback loops.

🌟 Key Takeaways

• CI pipelines are the backbone of modern DevOps practices.

• Jenkins + Git + Maven + SonarQube + Nexus = a strong CI/CD ecosystem.

• My VProfile project now has a reliable flow from code → test → quality check → artifact repository.
