Hey Techies! Welcome to this blog
In this blog, we are going to start Jenkins Journey.
What is Jenkins?
Jenkins is an open-source continuous integration-continuous delivery and deployment (CI/CD) automation software DevOps tool written in the Java programming language. It is used to implement CI/CD workflows, called pipelines.
Jenkins is a tool that is used for automation, and it is an open-source server that allows all the developers to build, test and deploy software. It works or runs on Java as it is written in Java. By using Jenkins we can make a continuous integration of projects(jobs) or end-to-endpoint automation.
Jenkins achieves Continuous Integration with the help of plugins. Plugins allow the integration of Various DevOps stages. If you want to integrate a particular tool, you need to install the plugins for that tool. For example Git, Maven 2 project, Amazon EC2, HTML publisher etc.
Tasks:

- Create a freestyle pipeline to print "Hello World!!
For creating a freestyle pipeline in Jenkins
First, we have to install Jenkins
Take an EC2 server on AWS then install Jenkins from Install Jenkins
Install Java first
Then Jenkins
To Check if Jenkins is running or not
sudo systemctl status jenkins
Let's start Jenkins, before open port 8080 on AWS in security groups as Jenkins listens to port 8080
Now your Jenkins is up and running on yourpublicip:8080
Now as per our task, we have to create a freestyle pipeline.
Create a New Jenkins Job:
Log in to your Jenkins server.
Click on "New Item" to create a new job.
Name your job (e.g., "Hello World").
Select the "Freestyle project" option.
now we will add a description to our Freestyle Project.
Save And Build
Click "Save" to save your job configuration.
Click "Build Now" to trigger your pipeline.
Now it's time to build our project using CI/CD on Jenkins.
View the Output
Once the build is complete, you can check the console output to see "Hello World!!" printed.
That's it! You've just created your first Jenkins freestyle pipeline. 🎉
