Jenkins

What is Jenkins?

Jenkins is a self-contained Java program, open-source automation server which can be used to automate all sorts of tasks related to building, testing, and delivering or deploying software.

Why Jenkins?

Jenkins is a software that allows continuous integration. While talking about DevOps, we cannot stop talking about Miss./Mr. Jenkins.

Jenkins Model:

Jenkins Terms:

Pipeline --> Jenkins Pipeline is a suite of plugins that supports implementing and integrating continuous delivery. This allows you to automate the SDLC and deliver important changes more efficiently to your users and customers.

Plugins --> A plugin is a simple software component which lets you and various features to the existing program. Plugin in Jenkins also works in the same way, plugin lets you add more features and functionality.

You can build, test, deploy, automate, integrate and trigger in a one stop place called Jenkins.

Advanced Jenkins:

Ok, I have installed Jenkins in my server, so am I a Jenkins professional? - Umm, absolutely yes, if you follow these important steps in you server.

1. Use Just Enough Pipeline
2. Say NO to pipelines in programming languages
3. Avoid creating a Monolithic Controller
4. Don't let your Plugins manage YOU
5. Use containers for build Agents

How does Jenkins work:

Developer --> code commit --> source code --> build --> test --> Deploy --> Notify

All this process(end-end) can be automated via Jenkins service which makes it more reliable for CI/CD.

Pros - Jenkins:

Fully Automated Service, Speed, Rapid Delivery, Reliability, Scale, Improved Collaboration, Security.

Then, why wait? Try to understand the need for your organization and if this practice helps, well you know what you need to do :)
