Day 26: Navigating the Terrain of Jenkins Declarative Pipeline

Day 26: Navigating the Terrain of Jenkins Declarative Pipeline

Greetings, DevOps enthusiasts! As we stride into Day 26 of our #90DaysOfDevOps journey, let's delve deep into the intricate world of Jenkins Declarative Pipeline Syntax—a pivotal element in contemporary CI/CD practices.

Unveiling the Essence:

Pipeline Basics: A pipeline is more than just a set of interconnected jobs. It's a strategic orchestration of processes, defining the very heartbeat of efficient workflows within the CI/CD landscape.

Declarative vs. Scripted: Today, we aim the spotlight at Declarative syntax—an evolved and streamlined approach compared to its counterpart, Scripted. Built with Groovy, Scripted was the first Jenkins DSL, offering flexibility but often accompanied by complexity. Declarative Pipeline, introduced later, is geared towards readability and simplicity.

The Why Behind the Pipeline:

"Pipeline-as-code" takes center stage as we treat the Continuous Delivery pipeline as an integral part of the application—versioned and scrutinized like any other code. By defining our Jenkins Pipeline in a Jenkinsfile committed to the source control repository, we gain immediate advantages:

  1. Automated Pipeline Build: Experience the seamless creation of a Pipeline build process for all branches and pull requests, automating mundane tasks and ensuring consistent builds.

  2. Integrated Code Review: Include the Pipeline in the code review and iteration process alongside the remaining source code. This integration streamlines collaboration and ensures that your CD pipeline evolves hand in hand with your application.

Diving into the Pipeline Syntax:

The syntax of a Declarative Pipeline is structured and intuitive. Here's a glimpse:

In this simple example:

  • agent: Defines where the pipeline will run.

  • stages: Encompasses various stages of your CI/CD process.

  • steps: Represents the individual steps within each stage, specifying the actions to be performed.
