Jenkins Pipeline 简介

Jenkins Pipeline (or simply "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.

Pipeline 定义

Declarative Pipeline
Scripted Pipeline (a limited form of Groovy)

Both are DSLs to describe portions of your software delivery pipeline.

Pipeline 可以使用下面三种方法创建:

Through Blue Ocean
Through the classic UI
In SCM

Jenkinsfile

Jenkinsfile (Declarative Pipeline)

pipeline {
    agent any

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

    post {
        always {
            junit '**/target/*.xml'
        }
        failure {
            mail to: team@example.com, subject: 'The Pipeline failed :('
        }
    }
}

全局变量

The Global Variable Reference only contains documentation for variables provided by Pipeline or plugins.

env

Environment variables can be set globally or per stage. Setting environment variables per stage means they will only apply to the stage in which they’re defined.

env.PATH

pipeline {
    agent any

    environment {
        COOKBOOK = 'propel_ha'
    }

    stages {
        stage('Build') {
            environment {
                DEPLOY_UI = 'yes'
            }
            steps {
                echo "Global Environment Variable COOKBOOK = $env.COOKBOOK"
                echo "Stage Environment Variable DEPLOY_UI = $env.DEPLOY_UI"

                sh 'env'
            }
        }
    }
}
