Jenkins Pipeline Basics

What is a Pipeline?

A Jenkins pipeline is a suite of plugins that supports implementing and integrating continuous delivery pipelines into Jenkins. A pipeline defines the entire build process, from source code management to deployment.

Pipeline Setup

To set up a Jenkins pipeline, follow these steps:

1. Install Jenkins and required plugins.
2. Create a new pipeline job.
3. Define your pipeline script.
4. Run the pipeline and view the results.

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo 'Building...'
            }
        }
        stage('Test') {
            steps {
                echo 'Testing...'
            }
        }
        stage('Deploy') {
            steps {
                echo 'Deploying...'
            }
        }
    }
}

Key Points

• Jenkins pipelines can be defined in two types: Declarative and Scripted.
• Pipelines can be triggered by various events, such as code commits or scheduled intervals.
• Stages represent distinct phases in the CI/CD process, making it easier to visualize the workflow.

Best Practices

Adhere to the following best practices when working with Jenkins pipelines:

• Keep the pipeline scripts version-controlled.
• Use shared libraries for reusable code.
• Employ proper error handling and notifications.
