What Is Jenkins, And Why Is It So Important For DevOps?

DevOps (a term used for a set of principles and practices that emphasize lean thinking and meaningful collaboration in software development) are at the absolute forefront of the digital transformation today. With increased automation and efficiency through continuous integration, continuous deployment, and monitoring – these hugely popular tools have shifted traditional paradigms in a new light.

What is Jenkins and Who Needs It?

Jenkins is an open-source automation server that helps developers to build, test and deploy their applications. It is a continuous integration (CI) tool that can be used to automate the process of creating a software build, testing it and then deploying it. Jenkins can be used to monitor the execution of repetitive jobs, such as building a software application or running tests. It can also be used to automatically run these jobs when certain conditions are met, such as when new code is pushed to a repository.

Jenkins is an important tool for DevOps teams as it can help to speed up the software development process by automating some of the tasks that need to be carried out. This can free up time for developers so that they can focus on more important tasks, such as writing code and fixing bugs. It can also help to reduce the chances of human error when carrying out these tasks manually.

If you are working in a DevOps team, then Jenkins is an essential tool that you should be using. It can help to improve the efficiency of your team and make the software development process smoother.

How to Choose Jenkins?

There are a few things to consider when choosing Jenkins for DevOps:

1. Ease of Use: One of the main reasons to use Jenkins is because it is easy to set up and use. You can quickly create a new job, add steps and parameters, and run the job with a few clicks. Additionally, the web interface is user-friendly and makes it easy to view build results and monitor job progress.

2. Scalability: Another big advantage of Jenkins is its scalability. If you have a large team of developers or a complex build process, Jenkins can easily handle it. There are a number of plugins available that allow you to extend Jenkins functionality and scale it to meet your needs.

Installing Repositories

If you’re used to working with Linux, then installing repositories will be a breeze. For those not so familiar, a repository is simply a collection of software packages that can be installed on your system. In the case of Jenkins, there are two repositories that we need to add in order to get the latest version:

1. Add the Jenkins repository to your system’s list of repositories.

2. Update your system’s package list to include the Jenkins repository.

Let’s take a look at each of these steps in more detail.

Adding the Jenkins Repository

The first step is to add the Jenkins repository to your system’s list of repositories. This can be done with a few simple commands:

1. wget -q -O – https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add –

2. sudo sh -c ‘echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list’

3. sudo apt-get update

These commands will download the necessary key for the Jenkins repository and add it to your system, as

Configuring Config Files

Plugin Life Cycle

In any software development process, there are certain stages that need to be completed in order for the final product to be released. These stages typically involve writing code, compiling it, testing it, and then packaging it up for deployment.

Jenkins is a tool that can help automate some of these steps, particularly the ones that happen after the code has been written. By using plugins, Jenkins can interface with just about any other tool in the development ecosystem, making it an important part of any DevOps toolchain.

One of the most important aspects of Jenkins is its plugin life cycle. Because Jenkins is open source, anyone can write a plugin and make it available to the community. When a new plugin is released, it goes through a rigorous approval process to ensure that it meets all the quality standards before being made available to users.

Once a plugin is approved, it goes through another process called certification. This is where theplugin author undergoes training to become a certified Jenkins expert. After certification, theplugin becomes available in the official Jenkins Plugin Repository.

from here on out, users can install, update, and manage their plugins directly from within Jenkins. This makes it easy to keep your development process up

Jobs Configuration

In Jenkins, a job is a basic building block. It represents a specific task that needs to be executed, such as building a software project or running a test suite. Jobs can be configured to run automatically at regular intervals, or they can be triggered manually when needed.

There are two types of jobs in Jenkins: freestyle jobs and pipeline jobs. Freestyle jobs are the more traditional type of job, and they provide a lot of flexibility in how they can be configured. Pipeline jobs, on the other hand, are designed to support continuous delivery pipelines. They include built-in support for things like checking out code from source control, running tests, and deploying software to production servers.

Jobs can be configure

Creating a Job from Template

Assuming you have a job template ready to go, creating a new job in Jenkins is a straightforward process. Here’s how it works:

1. Log into your Jenkins server and select ‘New Item’ from the sidebar.

2. Enter a name for your new job, then select ‘Copy existing item’ from the options.

3. Choose the job template you want to use as the basis for your new job.

4. Configure any additional settings for your new job, then click ‘Save’.

That’s all there is to it! By using templates, you can quickly and easily create new jobs in Jenkins without having to start from scratch each time.
