Welcome back, DevOps enthusiasts! If you successfully conquered Day 23 of our Jenkins CI/CD journey, congratulations! Today is all about putting your newfound knowledge into practice by completing a full-fledged Jenkins CI/CD project for your Node.js application. Get ready to build a beautiful CI/CD pipeline that will not only streamline your development process but also serve as a valuable addition to your resume.
Recap: Day 23 - Jenkins CI/CD Concepts
Before diving into today's project, make sure you've completed Day 23 and grasped the essential concepts of Jenkins CI/CD. Understanding the workflow and integration points is crucial for successfully implementing a robust CI/CD pipeline. If you need a quick refresher, revisit the materials from Day 23 to ensure you're well-prepared for today's hands-on tasks.
Task-01: Forking Repository and GitHub Integration
Step 1: Forking the Repository
To kick off your Jenkins CI/CD project, start by forking the provided repository on GitHub. This action creates a personal copy of the repository under your GitHub account, allowing you to freely experiment without impacting the original codebase.
Step 2: Connecting Jenkins Job to GitHub Repository
Now that you have your forked repository, establish a connection between Jenkins and GitHub. Jenkins can automatically build and deploy your application whenever changes are pushed to the repository. This integration streamlines the development process and ensures that your CI/CD pipeline is triggered seamlessly.
Step 3: GitHub WebHooks and CI/CD Setup
Take a moment to familiarize yourself with GitHub WebHooks. These are mechanisms that allow GitHub to notify external services, such as Jenkins, about events in your repository. Configure WebHooks to enable automatic triggering of the CI/CD pipeline whenever changes occur in your GitHub repository.
For a comprehensive guide on this process, refer to the suggested video. This resource provides a step-by-step walkthrough, ensuring you have a solid understanding of how GitHub integration and WebHooks work in tandem with Jenkins.
Task-02: Running the Application with Docker Compose
Step 1: Execute Shell Script in Jenkins
Inside your Jenkins job configuration, set up an Execute Shell build step. This step will be responsible for executing commands within the Jenkins environment. In this case, it will run your Node.js application using Docker Compose.
Step 2: Crafting a Docker Compose File
Create a Docker Compose file tailored to your Node.js application. This file should define the services, networks, volumes, and other configurations required for your application to run smoothly in a Dockerized environment. This is an excellent opportunity for you to contribute to the open-source community by sharing your Docker Compose file.
If you're new to Docker Compose, consider consulting the official documentation for guidance on its structure and usage.
Step 3: Run the Project and Celebrate
Once your Jenkins job is configured and your Docker Compose file is ready, execute the job. Watch as Jenkins automatically builds and deploys your Node.js application using the defined CI/CD pipeline.
As the final step, give yourself a treat! Celebrate the successful implementation of your CI/CD pipeline and the deployment of your application. This marks a significant achievement in your journey towards mastering DevOps practices.
Conclusion
By completing these tasks, you've taken a big stride in incorporating CI/CD into your Node.js development workflow. The integration of Jenkins, GitHub, and Docker Compose not only automates your processes but also lays the foundation for efficient and scalable software development.
Stay tuned for more challenges and projects as you continue to enhance your DevOps skills.
