USE CASES OF JENKINS

What is Jenkins and why we use it?

Jenkins is an open-source automation tool written in Java with plugins built for Continuous Integration purposes. Jenkins is used to build and test your software projects continuously making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build.

Who is using Jenkins?

Many companies, open source projects and other organisations use Jenkins. Here are just a few of them.

JENKINS WITH GITHUB

Jenkins, itself located on GitHub, has a number of plugins for integrating into GitHub. The primary avenues for integrating your Jenkins instance with GitHub are:

• “build integration” — using GitHub to trigger builds
• “authentication integration” — using GitHub as the source of authentication information to secure a Jenkins instance.

With the help of the Git plugin Jenkins can easily pull source code from any Git repository that the Jenkins build node can access.

The GitHub plugin extends upon that integration further by providing improved bi-directional integration with GitHub. Allowing you to set up a Service Hook which will hit your Jenkins instance every time a change is pushed to GitHub.

Using the GitHub Authentication plugin it is possible to use GitHub’s own authentication scheme for implementing authentication in your Jenkins instance.

The setup guide will help walk you through configuring the GitHub OAuth side, and your Jenkins instance, to provide easy authentication/authorization for users.

JENKINS WITH FACEBOOK

At Facebook, code review occupies a central position. Every line of code that’s written is reviewed by a different engineer than the original author. This serves multiple purposes: the original engineer is motivated to ensure that the code is of high quality, the reviewer comes with a fresh mind and might find defects or suggest alternatives, and, in general, knowledge about coding practices and the code itself spreads throughout the company.

Developers must also support the operational use of their software — a combination that’s become known as “DevOps.” This further motivates writing good code and testing it thoroughly. Developers’ personal stake in keeping the system running smoothly complements the engineering procedures and lets the system maintain quality at scale.

Jenkins on AWS

Jenkins is an open-source automation server that integrates with a number of AWS Services, such as AWS CodeCommit, AWS CodeDeploy, Amazon EC2 Spot, and Amazon EC2 Fleet. You can use Amazon Elastic Compute Cloud (Amazon EC2) to deploy a Jenkins application on AWS in a matter of minutes.

In AWS, Jenkins software in a CI/CD pipeline, you can add Automation as a post-build step to pre-install application releases into Amazon Machine Images (AMIs). You can also use the Jenkins scheduling feature to call Automation and create your own operating system (OS) patching cadence.
