๐ DevOps CI/CD: A Complete Guide Using Jenkins
๐ Introduction to DevOps CI/CD
DevOps CI/CD (Continuous Integration and Continuous Deployment) is a crucial process that ensures seamless software development, testing, and deployment. Jenkins, a widely used automation tool, plays a vital role in orchestrating the CI/CD pipeline. Let's dive into the lifecycle of a DevOps CI/CD pipeline and its key components.
๐ DevOps CI/CD Pipeline Lifecycle
1๏ธโฃ Developers Create the Source Code
Developers write and maintain the source code of applications.
2๏ธโฃ Save Source Code Changes in Source Code Repository (GitHub)
Version control tools like Git and GitHub help manage code changes effectively.
3๏ธโฃ SCM (Source Code Management) Checkout
Jenkins pulls the latest source code from the repository to trigger the pipeline.
4๏ธโฃ Build the Code
Tools like Maven, Gradle, and Ant compile the code into an executable format.
5๏ธโฃ Create Artifacts
The build process generates artifacts such as JAR, WAR, or Docker images for deployment.
6๏ธโฃ Unit Testing
Automated unit tests validate individual components of the application.
7๏ธโฃ Promote Changes for Further Testing
Successful builds are promoted to different environments for additional testing.
8๏ธโฃ Automated Testing
Tools like Selenium, JUnit, and TestNG automate functional and performance testing.
9๏ธโฃ Deploy to Production Environment
Successful releases are automatically deployed to production environments.
๐ Continuous Monitoring & Feedback
Monitoring tools like Prometheus, Grafana, and ELK stack ensure performance tracking and issue detection.
