Hi there! Setting up a continuous integration pipeline can seem like a big and difficult task, but it's actually pretty easy when you break it down! I'm going to explain it in a way that's easy for someone 10 years old like you to understand. 🚀

First, let's talk about what a continuous integration pipeline is. Imagine you're building a big Lego castle, and you want to make sure that all the different parts fit together correctly before you finish building it. That's kind of like what a continuous integration pipeline does for software. It makes sure that all the different parts of your code work together before you release it to the public.

To set up a continuous integration pipeline, you need a few things: 🔥

• A code repository: This is where you store all the different parts of your code. It's kind of like a big box where you keep all your Legos.

• A continuous integration tool: This is the tool that actually checks that all the different parts of your code fit together correctly. It's like the person who helps you build your Lego castle.

• A server: This is where the continuous integration tool will run. Think of it like the table you use to build your Lego castle.

There are many tools that can be used as Continuous Integration (CI) tools. Some popular ones are Jenkins, Travis CI, CircleCI, Gitlab CI/CD, etc. 🚩

For this example, I will use Jenkins, since is one of the most widely used.

• First, you will need to install Jenkins on your server. You can do this by following the instructions on the Jenkins website.

sudo apt-get update
sudo apt-get install Jenkins

• Next, you need to create a new Jenkins job for your project. Think of this like a special project box for your Lego castle. ✌

• Once you have the job set up, you need to configure it to use your code repository. You can do this by connecting Jenkins to your code repository service, like GitHub.

git remote add origin https://github.com/yourusername/yourproject.git
git push -u origin master

• Next, you will want to set up a build script. This is like the instructions for building your Lego castle. The build script will tell Jenkins what to do when it runs your code. It will often compile your code and run the unit test. For example, if your code is written in Java, your build script might look like this:

mvn clean install

• Finally, you want to set up a notification. This is like the person who tells you when your Lego castle is finished. In this case, Jenkins will send you an email or message when the build is complete.

And that's it! Now, every time you make changes to your code, Jenkins will automatically run the build script and check that everything works correctly. This way, you'll know right away if there are any problems and can fix them before you release your code to the public. 👨‍💻

It is important to note that a CI pipeline is highly customizable, and you might have different needs and use cases, but this is a basic setup that you can use as a starting point. And who knows, maybe in a near future you will be building the most amazing lego castle with the help of a CI pipeline. 🎨

I hope this helped and was easy to understand! Let me know if you have any more questions.
