If you have ever had questions regarding DevOps and have been confused by the many tools and terms, don't worry, you are not the only one. Jenkins is one of the most utilized and understandable tools out there that makes DevOps simple. Whether you are a student, a fresher, or simply an IT professional looking to upskill in your career, it is incredibly easy to learn Jenkins and gain a baseline of knowledge about automation and continuous integration.
In this blog, we will consider the topics of Jenkins Essentials using plain language and explain how it continues to simplify DevOps processes for organizations large and small.
What is Jenkins and why is it Important?
Time for some basics. Jenkins is an open-source automation server. Or, in simple terms, it's a “helper robot” to automate repetitive tasks for the developers and operations team.
For example: Imagine a developer writes some code for a new feature. Normally, they would have to test it and then deploy it manually. With Jenkins, the process begins with the developer committing the code to a source code repository. Then, Jenkins automatically builds, tests, and deploys the code.
This results in fewer human errors, quicker code delivery, and happier teams.
As we discussed earlier in the DevOps realm, speed and reliability are critical. Jenkins is one of the most popular tools for accomplishing this.
Regarding Jenkins Essentials: Core features
If you're a beginner, here are the essential aspects of Jenkins:
Automation of Builds and Deploys: Say goodbye to performing uploads manually - Jenkins does it for you automatically.
Continuous Integration (CI): Each time developers change code, Jenkins integrates it and tests it against the resident code.
This keeps you from having the "works on my machine" problem.
Plugins and Flexible Extensibility: Jenkins has thousands of plugins, allowing it to integrate with just about any tool (e.g., Git, Docker, Kubernetes).
Pipeline as Code: You can now define a workflow (build → test → deploy) in a pipeline concept that guarantees a repeatable and reliable experience.
Open Source and Community Support: Jenkins is open-source and free to use, with a very large support network that spans the globe.
Why Jenkins is a Good Tool for Beginners
If you are getting started in DevOps, Jenkins is one of the best tools to learn about first. Here's why:
Easy Start: You can install Jenkins on your computer or a server with just a few steps.
Practical Experience: You'll gain hands-on experience installing and configuring Jenkins while building a practical CI/CD pipeline on it on your own.
Career Value: The vast majority of companies that start to adopt DevOps incorporate Jenkins into their pipeline in one way or another. Learning Jenkins will also enhance your employment prospects and job opportunities.
Free and Open Source: You can get started learning about Jenkins without spending any money. This is in contrast to expensive enterprise systems that you have no hope of doing anything with before you invest in learning.
How Jenkins Simplifies DevOps
DevOps is about collaboration, speed, and efficiency. Jenkins embodies this mentality by automating tasks that would otherwise hold teams up.
For Developers: Jenkins ensures that any time code is changed, it is tested automatically.
For Operations Teams: Jenkins ensures that deployments happen quickly and are less error-prone.
For Business: Projects get delivered quickly, and customers experience updates sooner.
This is why Jenkins is a tool that everyone working in DevOps will become familiar with.
Getting Started with Jenkins
Here’s a simple roadmap if you are going to start learning Jenkins:
1. Jenkins Installation - Download Jenkins from the official website and run it in your local environment.
2. Dashboard - Go through the simple UI and familiarize yourself with creating a job.
3. Integrate GitHub - Try to integrate Jenkins with GitHub, and automate builds.
4. Pipelines - Learn how to create simple CI/CD pipelines.
5. Plugins - Add plugins for Docker, Kubernetes, or any other cloud service you want to see Jenkins in modern DevOps tools.
If you are looking for a structured approach, companies like Evision Technoserve (a Leading Training and Placement Company in India) offer job-guaranteed programs and a course with a placement guarantee, so you can master Jenkins along with other DevOps tools.
