Creating your first Pipeline 

What is a Jenkins Pipeline?

Jenkins Pipeline (or simply "Pipeline") is a suite of plugins which supports implementing and integrating continuous delivery pipelines into Jenkins.

continuous delivery pipeline is an automated expression of your process for getting software from version control right through to your users and customers.

Jenkins Pipeline provides an extensible set of tools for modeling simple-to-complex delivery pipelines "as code". The definition of a Jenkins Pipeline is typically written into a text file (called a Jenkinsfile) which in turn is checked into a project`s source control repository.

  To get started quickly with Pipeline:

  1. Copy one of the examples below into your repository and name it Jenkinsfile
  2. Click the New Item menu within Jenkins
  3. Provide a name for your new item (e.g. My Pipeline) and select Multibranch Pipeline
  4. Click the Add Source button, choose the type of repository you want to use and fill in the details.
  5. Click the Save button and watch your first Pipeline run!

You may need to modify one of the example Jenkinsfile`s to make it run with your project. Try modifying the sh command to run the same command you would run on your local machine.

After you have setup your Pipeline, Jenkins will automatically detect any new Branches or Pull Requests that are created in your repository and start running Pipelines for them.

Quick Start Examples

Below are some easily copied and pasted examples of a simple Pipeline with various languages.

Java

Jenkinsfile (Declarative Pipeline)

pipeline {

    agent { docker { image `maven:3.3.3` } }

    stages {

        stage(`build`) {

            steps {

                sh `mvn --version`

            }

        }

    }

}

 

Node.js / JavaScript

Jenkinsfile (Declarative Pipeline)

pipeline {

    agent { docker { image `node:14-alpine` } }

    stages {

        stage(`build`) {

            steps {

                sh `npm --version`

            }

        }

    }

}

 

Ruby

Jenkinsfile (Declarative Pipeline)

pipeline {

    agent { docker { image `ruby` } }

    stages {

        stage(`build`) {

            steps {

                sh `ruby --version`

            }

        }

    }

}

 

Python

Jenkinsfile (Declarative Pipeline)

pipeline {

    agent { docker { image `python:3.5.1` } }

    stages {

        stage(`build`) {

            steps {

                sh `python --version`

            }

        }

    }

}

 

PHP

Jenkinsfile (Declarative Pipeline)

pipeline {

    agent { docker { image `php` } }

    stages {

        stage(`build`) {

            steps {

                sh `php --version`

            }

        }

    }

}

 

Go

Jenkinsfile (Declarative Pipeline)

pipeline {

    agent { docker { image `golang` } }

    stages {

        stage(`build`) {

            steps {

                sh `go version`

            }

        }

    }

}
