Welcome to Day 25 of the 90 Days of DevOps challenge! Today, we’re taking a moment to wrap up the Jenkins CI/CD project from Day 24 and focus on adding detailed documentation. Proper documentation is crucial for sharing your work and understanding it in the future.

Task-01: Document Your Jenkins CI/CD Project

1. Create a Comprehensive README

   Start by drafting a README.md file for your Jenkins CI/CD project. This document should cover all the steps from cloning the repository to configuring webhooks and deploying your Node.js application.

   Here’s a basic structure for your README:

   • Project Overview: Describe what your project does and why it’s important.

   • Prerequisites: List any tools or software required, like Jenkins, Docker, and Node.js.

   • Setup Instructions: Provide step-by-step instructions for setting up the project. Include how to fork the repository, create a Jenkins job, and configure GitHub webhooks.

   • Docker Configuration: Explain the Docker Compose setup and how to use it in Jenkins.

   • Running the Project: Detail how to manually trigger builds and verify the application.

   • Troubleshooting: Offer solutions to common issues that might arise.

    # Jenkins CI/CD for Node.js Application

    ## Project Overview
    This project sets up a CI/CD pipeline for a Node.js application using Jenkins and Docker.

    ## Prerequisites
    - Jenkins
    - Docker
    - Node.js
    - GitHub account

    ## Setup Instructions
    1. Fork the repository from [GitHub](https://github.com/LondheShubham153/node-todo-cicd).
    2. Create a new Jenkins job and configure source code management with Git.
    3. Set up GitHub webhooks to trigger Jenkins builds.
    4. Create a `docker-compose.yml` file and configure build steps in Jenkins.

    ## Docker Configuration
    - Define services in `docker-compose.yml`.
    - Use `docker-compose up -d` to start services and `docker-compose down` to stop.

    ## Running the Project
    - Trigger a build in Jenkins or push a change to GitHub.
    - Verify the application is running at `http://localhost:5000`.

    ## Troubleshooting
    - Ensure all services are up and running.
    - Check Jenkins build logs for errors.

2. Update Your Resume

   Add the completed Jenkins CI/CD project to your resume. Highlight the skills you used and the outcome of the project. This addition will showcase your practical experience with CI/CD pipelines and containerization.

Conclusion

Today’s focus was on completing and documenting your Jenkins CI/CD project. By creating a detailed README and adding the project to your resume, you’re setting yourself up for future success. Keep setting small, achievable goals to maintain your momentum and celebrate your progress. 🌟
