Using Jenkins as your go-to CI/CD tool

Introduction

Everyone loves Agile and the way it is replacing all the older methodologies and development models with a streamlined and sustainable system for faster delivery cycles. However, the ever-prevailing Manual testing practice has always kept the QA teams from entirely adopting Continuous Integration and Continuous Delivery, making Agility unreachable. Fortunately, tools like Jenkins help reach the goals of the CI/CD pipeline, i.e., to maintain a continuous flow of software updates in production and shorter release cycles at reduced costs.

Jenkins and its relation to DevOps and CI/CD

We know that Continuous Integration and Continuous Delivery are integral parts of the DevOps process and inevitable in the Agile approach. It has completely changed the way the development and QA team delivered the software. Let us briefly understand DevOps, CI/CD pipeline, and Jenkins before moving ahead.

In simple terms, DevOps is an engineering approach to unify the development and IT operations to improve and minimize the software development lifecycle. It aims at delivering high-quality software at faster speeds as compared to traditional methods.

Continuous Integration/Continuous Delivery (CI/CD) pipeline is the set of steps aimed at improving the software delivery using the DevOps approach. It enables the development team to handle frequent code changes for faster and reliable product delivery. This entire process is automated using CI/CD tools like Jenkins that provide continuous monitoring of the app and providing reports on the status.

Jenkins

History

Jenkins was earlier known as Hudson. It was started in 2004 by Kohsuke Kawaguchi, who worked as a developer in Sun Microsystems. Kohsuke did not like that he had to build the code and fix the errors repetitively. So, he created an automation server to do the job in lesser time. In 2011, he renamed Hudson as Jenkins because Oracle, who owned Sun, had a dispute with Hudson’s open source community. Kohsuke open-sourced it to the community and made it available to the world. Soon Jenkins became popular and still leads the market.

Key Features

  • Jenkins is a leading open-source CI/CD tool used to deliver apps faster by introducing automation at different software development stages

Why Choose Jenkins as our go-to CI/CD tool?

a. Concurrent Approach:

The development team is always building some software, and the need for development is ever-prevailing. The strength of Jenkins lies in handling this scenario adeptly with the help of a concurrent and parallel approach to CI/CD. This feature allows Jenkins to perform multiple types of tasks parallelly, allowing it more space and time for handling what is crucial. It enables teams to build, test, deliver, deploy faster than ever.

b.Pipeline

For businesses, Jenkins standardizes the Software development process, allows quick adoption of changes and control over software quality. Jenkins gives comfort and confidence to the team because you know that the final product has gone through multiple checks and tests before reaching the end customer. Well-established pipelines act as a guideline for the new teams. Developers, on the other hand, establish a streamlined process for developing similar kinds of software. With the help of flexible and equipped pipeline configuration language, one can perform CI/CD, successfully.

c. Tools Versions

Using the right version is critical for Jenkins CI/CD pipelines. Jenkins only needs a single line of source code to bootstrap any development tool version. There can be many tool versions of Jenkins, but the team has to run and add only required versions in their respective pipelines.

d.Plugins

Plugins help integrate multiple enterprise systems in a significantly lesser time. Although there should be proper management of the plugins, Jenkins Plugins, however, smoothen the integration with the third-party platforms. Jenkins provides a default plugin list for integrating different tools and services. The most commonly used plugins are Kubernetes, Jenkins templating engine, Credentials, etc.

BEFORE AND AFTER JENKINS SCENARIO

Let’s have a look at a before-after scenario to understand how Jenkins has changed the life of the developers and how it overcame the shortcomings of the traditional approaches.

What makes Jenkins so popular?

  • Jenkins has an open community that usually organizes meetings every month for feedback and suggestions to build the Jenkins Project.

Concerns relating to Jenkins CI/CD tool

Every good thing comes with a cost. Jenkins is a powerful tool but is not flawless. Here are a few drawbacks that you need to keep in mind:

  • Using Jenkins, the developers can continuously integrate the changes, making the process super easy for them

Conclusion

Jenkins- 3 Key highlights:

DevOps ecosystem is ever-changing and the tools in this space are highly vulnerable to these changes. The challenges faced because the introduction of new tools poses high competition. But Jenkins is positioned at a promising place in this competitive environment because of its versatility. Hence, it remains one of the best CI/CD tools in the market. Jenkins adds value to the agility system by providing the CI services. In order to boost the functionality of Jenkins, cloud-based cross-browser testing platforms like pCloudy can be used to automate browser testing activities and save time.
