Day-33: Jenkins Pipelines (Freestyle vs Declarative)

🚀 1️⃣ What is a Jenkins Pipeline?

A Jenkins Pipeline defines your CI/CD workflow as code.

Instead of manually clicking in the UI, you write a script (Jenkinsfile) that tells Jenkins how to:

• Pull code
• Build
• Test
• Deploy
• Notify

Jenkins Pipelines are more scalable, automated, and version-controlled.

2️⃣ Pipeline Types

Jenkins supports two main pipeline types:

A) Freestyle Jobs

B) Pipeline Jobs (Scripted or Declarative)

Let’s break them down 👇
