Jenkins Pipeline is a combination of plugins that support the integration and implementation of continuous delivery pipelines using Jenkins. A pipeline has an extensible automation server for creating simple or complex delivery pipelines "as code," via pipeline DSL (Domain-specific Language).

gCubeRelease Pipeline Project

In gCube we use a Pipeline to trigger the builds of jobs forming a gCube Release. The pipeline project is available at: https://jenkins.d4science.org/job/gCube-Release/

Parameters

Triggers

No triggers are defined because the pipeline is expected to be manually launched by the Release Manager:

It can be changed according to the release needs and the availability of a sufficient number of dedicate agents in Jenkins.

Git

The pipeline definition is maintained in a Git repository. This section connects the project to the Git repository.

Jenkins Pipeline Definition

Git Repository

The definition of the gCube release pipeline is maintained in this Git Repository: https://code-repo.d4science.org/gCubeCI/gCubeRelease

Requirements

Basic Structure

Jenkinsfile defines a Declarative Pipeline. The Pipeline’s code defines the entire build process of a gCube Release.

This is the stub of the gCubeRelease pipeline.

  
  // manage options and settings

  // pipeline
  pipeline {
        // run only on agents with the label
        agent { label 'pipeline-agent' }

        // expected input parameters
        parameters {
            string(name: 'myInput', description: 'Some pipeline parameters')
        }


        stages {
            stage('preliminary steps') {
               //prepare the environment for the builds
                steps {
                       //execute steps here if needed
                }
            }
            stage('build group 1') {
                steps {
            	   withMaven(..maven settings here..) {
                       build 'job name 1'
                       build 'job name 2'
                       build 'job name 3'
                       build 'job name 4'
                    }
                    echo 'Done with group 1'
                }
            }
            stage('build group 2') {
                steps {
                    ...
                }
            }
        }
	// post-build actions
	post {
		always {
			echo 'This will always run'
		}
		success {
			echo 'This will run only if successful'
		}
		failure {
			echo 'This will run only if failed'
		}
		unstable {
			echo 'This will run only if the run was marked as unstable'
		}
		changed {
			echo 'This will run only if the state of the Pipeline has changed'
			echo 'For example, if the Pipeline was previously failing but is now successful'
		}
	}
