# Jenkins Pipeline 例子 #

## 前言 ##

Jenkins Pipeline as code 支持两种语法：

*  Declarative Pipeline
 *  Scripted Pipeline

Declarative Pipeline 可以使用Jenkins 的一些内置方法来简化Jenkinsfile， 但是Scripted Pipeline更加灵活。好在Jenkins在Declarative Pipeline中也支持通过`script {...}` 来嵌入Scripted Pipeline。

Jenkins Pipeline 官方文档：  
[https://jenkins.io/doc/book/pipeline/][https_jenkins.io_doc_book_pipeline]  
[https://go.cloudbees.com/docs/cloudbees-documentation/use/reference/pipeline/\#\_pipeline\_syntax\_reference][https_go.cloudbees.com_docs_cloudbees-documentation_use_reference_pipeline_pipeline_syntax_reference]

注：Jenkins的主要开发者来自CloudBees

## Jenkins Pipeline 例子 ##

Jenkins在Pipeline Job的配置界面提供了Pipeline Syntax 教程, 并提供了Pipeline Syntax Generator来帮助生成Pipeline片段。

但是有时候这仍然不足够，需要一些“真实”的Jenkins Pipeline 例子来帮助我们更加快速的开发Pipeline。

我正在整理相关Jenkins Pipeline的例子放在GitHub上：  
[https://github.com/cookcodeblog/jenkins-pipeline-examples][https_github.com_cookcodeblog_jenkins-pipeline-examples]

Jenkins 官方Pipeline例子：

Jenkins 官方Pipeline的GitHub repository:

其中 `.groovy` 文件都是Jenkins Pipeline的例子。

## Jenkins Pipeline 库文件 ##

Jenkins Pipeline也支持库文件 （Shared Libraries) 从而可以避免在不同repository的Jenkinsfile中写重复的代码。参见：

[https://jenkins.io/doc/book/pipeline/shared-libraries/][https_jenkins.io_doc_book_pipeline_shared-libraries]

第三方Jenkins Pipeline库文件：

[https://github.com/fabric8io/jenkins-pipeline-library][https_github.com_fabric8io_jenkins-pipeline-library]  
[https://github.com/funkwerk/jenkins-workflow][https_github.com_funkwerk_jenkins-workflow]  
[https://github.com/docker/jenkins-pipeline-scripts][https_github.com_docker_jenkins-pipeline-scripts]

对库文件部分，以后使用到再补充。

## Jenkins Pipeline 小技巧 ##

1.  在一个项目的repository下分别创建Jenkinsfile来作持续集成、部署到测试环境、部署到生产环境，例如：
    
    1.  ci.Jenkinsfile 用来作持续集成，包括代码静态分析、单元测试、打包、打镜像，但是不把包/镜像推送到仓库，也不部署到环境

1.  test.Jenkinsfile 用来做测试环境的持续交付，除了持续集成的步骤外，还要把包/镜像推送到仓库，并且部署到测试环境
2.  prod.Jenkinsfile 用在测试环境验证过的包/镜像部署到生产环境，而不是再从源代码开始打包

1.  使用Jenkins Pipeline的replay功能来调试Pipeline，可以避免修复错误前需要频繁提交Jenkinsfile
