I take my time to read every single post from you, because it gives me more understanding of DevOps as a beginner, but as said earlier, it would be better if you could make it more practical,with codes and Screenshot. It could even be a YouTube video. If you are recording too, please the time should not be stretched. Say minimum 1hour, maximum 2 hours. My humble suggestion and request

@innocentia_azal, @red_ Here are the key changes and improvements made from the old article to the new, more detailed version:

Expanded Explanation of CI/CD:
- Provided a more in-depth breakdown of Continuous Integration (CI), Continuous Delivery (CD), and Continuous Deployment. The new article explains each concept in greater detail, highlighting their purpose and benefits.
Step-by-Step Guide for Creating a CI/CD Pipeline:
- Added a detailed step-by-step guide on how to set up a complete CI/CD pipeline using Jenkins, starting from installing Jenkins to writing and configuring a Jenkinsfile.
- Step 1: Setting up Version Control with GitHub now includes instructions on how to create and push code to a GitHub repository.
- Step 2: Choosing a CI/CD Tool focuses on Jenkins, explaining why it’s a good option.
- Step 3: Jenkins Pipeline Setup has been significantly expanded with sub-steps on installing Jenkins, configuring Jenkins for Git, and setting up credentials.
- Step 4: Writing a Basic Jenkins Pipeline includes a detailed Jenkinsfile example, explaining each section (checkout, build, test, deploy).
- Step 5: Deploy the Application now features a concrete example of deploying an app to Heroku, providing actual deployment steps.
Added Jenkins Pipeline Script:
- A complete Jenkinsfile example has been added, showing how to automate the build, test, and deployment stages for a Node.js application.
Heroku Deployment Integration:
- New instructions on how to integrate Heroku deployment into your Jenkins pipeline with specific steps for setting up the Heroku CLI and updating the Jenkinsfile with Heroku deployment commands.
Best Practices for CI/CD:
- A new section discussing best practices for building efficient and maintainable CI/CD pipelines, such as automating everything, failing fast, and keeping pipelines simple.
Clearer Pipeline Stages Breakdown:
- Each pipeline stage (checkout, build, test, deploy) is now broken down with explanations of their purpose and Jenkins syntax.
Conclusion Section Expanded:
- The conclusion now emphasizes advanced features of Jenkins and encourages readers to explore distributed builds, Docker, Kubernetes, and other DevOps integrations, providing a path for further learning.

These changes make the article much more detailed and actionable for beginners by offering practical, hands-on steps while explaining the theory behind CI/CD.

Where is the "Beginner guide"? The steps do not demonstrate anything actionable. This is just abstract ideas and not a guide or how-to.

Thank you for your honest feedback! @red_ 🙏 I appreciate you taking the time to read the article and share your thoughts.

You're absolutely right that actionable steps are key in a beginner's guide, and I realize I could have included more specific, step-by-step instructions to make it clearer and more practical. I’ll update the article soon with detailed examples, commands, and screenshots to help guide beginners through setting up their first CI/CD pipeline.

In the meantime, if you have any particular areas you’d like me to focus on or if you need help getting started, feel free to let me know! I’d love to make the guide as helpful as possible.

Thanks again for your input—feedback like yours helps me improve future content!

Just create an article that does what it says what it will do : "we will take you through a step-by-step approach to understanding CI/CD concepts and setting up your first pipeline from scratch."

I cannot setup a pipeline from scratch with your article.

A comprehensive and introductory guide to the concept of CI/CD process. Hopefully there would be a how to section to setup a CI/CD pipeline with one of your recommended tools as an example.
