Scripted Pipeline Syntax in Jenkins

1. Introduction

The Jenkins Scripted Pipeline Syntax provides a way to define your build process as a code, enabling better version control and easier maintenance. Unlike Declarative Pipelines, Scripted Pipelines offer more flexibility and control over the pipeline execution.

2. Key Concepts

**Pipeline**: A series of automated processes defined in code.
**Node**: A machine on which Jenkins runs the pipeline.
**Stage**: A block of code that contains a sequence of steps.
**Step**: A single task that executes as part of a stage.

3. Syntax Structure

Scripted Pipelines are written in Groovy. Below is the basic structure:

node {
    stage('Build') {
        // Build steps
    }
    stage('Test') {
        // Test steps
    }
    stage('Deploy') {
        // Deploy steps
    }
}

4. Step-by-Step Guide

**Set up Jenkins**: Ensure Jenkins is installed and running.
**Create a new pipeline job**: Navigate to Jenkins dashboard and create a new pipeline.
**Define the pipeline**: In the pipeline configuration, add your scripted pipeline code.
**Save and build**: Save your changes and build the pipeline.

5. Best Practices

Always keep your pipeline code in version control systems like Git for better tracking and collaboration.

Use descriptive stage names.
Keep your pipeline code modular by using functions.
Implement error handling within your pipeline.

6. FAQ

What is the difference between Declarative and Scripted Pipelines?

Declarative Pipelines are more structured and easier to read, while Scripted Pipelines offer more flexibility and control.

Can I use Groovy libraries in my Scripted Pipeline?

Yes, you can import and use Groovy libraries in your Scripted Pipeline.
