⚒Day 24- Complete Jenkins CI/CD Project

Hello, DevOps enthusiasts! If you've made it through Day 23 of our Jenkins CI/CD journey, congratulations are in order! Today is all about putting your newfound knowledge into action by completing a comprehensive Jenkins CI/CD project for your Node.js application. This project will not only streamline your development process but also serve as a standout addition to your resume. So, get ready to build a robust CI/CD pipeline that showcases your skills and enhances your DevOps prowess!

Recap: Day 23 - Jenkins CI/CD Concepts

Before embarking on today's project, it's essential to have a solid grasp of the Jenkins CI/CD concepts covered on Day 23. Understanding the workflow and integration points is key to implementing a robust CI/CD pipeline successfully. If you need a quick refresher, take some time to revisit the Day 23 materials. Being well-prepared will ensure you get the most out of 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.
