如何使用一些可配置的公共阶段为jenkins管道创建模板？

Question

基于以下文章的思想：

https://jenkins.io/blog/2017/10/02/pipeline-templates-with-shared-libraries/

我有以下管道：

pipeline {
    agent any
    environment {
        branch = 'master'
        scmUrl = 'ssh://git@myScmServer.com/repos/myRepo.git'
        serverPort = '8080'
        developmentServer = 'dev-myproject.mycompany.com'
        stagingServer = 'staging-myproject.mycompany.com'
        productionServer = 'production-myproject.mycompany.com'
    }
    stages {
        stage('checkout git') {
            steps {
                git branch: branch, credentialsId: 'GitCredentials', url: scmUrl
            }
        }

        stage('build') {
            steps {
                sh 'mvn clean package -DskipTests=true'
            }
        }

        stage ('test') {
            steps {
                parallel (
                    "unit tests": { sh 'mvn test' },
                    "integration tests": { sh 'mvn integration-test' }
                )
            }
        }

        stage('deploy development'){
            steps {
                deploy(developmentServer, serverPort)
            }
        }

        stage('deploy staging'){
            steps {
                deploy(stagingServer, serverPort)
            }
        }

        stage('deploy production'){
            steps {
                deploy(productionServer, serverPort)
            }
        }
    }
    post {
        failure {
            mail to: 'team@example.com', subject: 'Pipeline failed', body: "${env.BUILD_URL}"
        }
    }
}

然后，本文展示了如何通过以下方式通过自定义参数使代码完全可重用：

myDeliveryPipeline(branch: 'master', scmUrl: 'ssh://git@myScmServer.com/repos/myRepo.git',
                   email: 'team@example.com', serverPort: '8080',
                   developmentServer: 'dev-myproject.mycompany.com',
                   stagingServer: 'staging-myproject.mycompany.com',
                   productionServer: 'production-myproject.mycompany.com')

这里描述的内容只能解决我的一部分问题，因为我还需要注入一些自定义阶段。

回到管道上，这些将是模板部分：

pipeline {
    agent any
    environment {
        branch = 'master'
        scmUrl = 'ssh://git@myScmServer.com/repos/myRepo.git'
        serverPort = '8080'
        developmentServer = 'dev-myproject.mycompany.com'
        stagingServer = 'staging-myproject.mycompany.com'
        productionServer = 'production-myproject.mycompany.com'
    }
    stages {
        stage('checkout git') {
            steps {
                git branch: branch, credentialsId: 'GitCredentials', url: scmUrl
            }
        }

        stage('build') {
            steps {
                sh 'mvn clean package -DskipTests=true'
            }
        }

        stage ('test') {
            steps {
                parallel (
                    "unit tests": { sh 'mvn test' },
                    "integration tests": { sh 'mvn integration-test' }
                )
            }
        }

        // CUT HERE THE PART TO BE INJECTED
    }
    post {
        failure {
            mail to: 'team@example.com', subject: 'Pipeline failed', body: "${env.BUILD_URL}"
        }
    }
}

要具备以下条件：

myDeliveryPipeline(branch: 'master', scmUrl: 'ssh://git@myScmServer.com/repos/myRepo.git',
                   email: 'team@example.com', serverPort: '8080',
                   developmentServer: 'dev-myproject.mycompany.com',
                   stagingServer: 'staging-myproject.mycompany.com',
                   productionServer: 'production-myproject.mycompany.com') {

       stage('deploy development'){
                steps {
                    deploy(developmentServer, serverPort)
            }
        }

        stage('deploy staging'){
            steps {
                deploy(stagingServer, serverPort)
            }
        }

        stage('deploy production'){
            steps {
                deploy(productionServer, serverPort)
            }
        }
}
