jenkins pipeline 是Jenkins中实现和集成连续交付的一套插件。持续交付是将软件的版本控制直接传给客户和用户的自动化表达。

 

pipeline features:

• Code(编码）: Pipelines are implemented in code and typically checked into source control, giving teams the ability to edit, review, and iterate upon their delivery pipeline.

• Durable（耐用的）: Pipelines can survive both planned and unplanned restarts of the Jenkins master.

• Pausable（可暂停的）: Pipelines can optionally stop and wait for human input or approval before continuing the Pipeline run.

• Versatile（通用的）: Pipelines support complex real-world CD requirements, including the ability to fork/join, loop, and perform work in parallel.

• Extensible（可扩展的）: The Pipeline plugin supports custom extensions to its DSL [1] and multiple options for integration with other plugins.

 

pipeline concept:

pipeline 管道的代码定义了整个构建过程，通常包括构建应用程序、测试应用程序和交付应用程序的阶段。

node 节点是Jenkins环境的一部分，能够执行管道的机器。

stage 块定义了通过整个管道执行的任务的概念上不同的子集(例如，“Build”、“Test”和“Deploy”stage)，许多插件都使用它来可视化或显示Jenkins管道的状态/进度。

step 一个单一的任务。基本上，一个步骤告诉Jenkins在特定时间点(或过程中的“步骤”)要做什么。例如，要执行shell命令，请使用sh步骤:sh 'make'。当插件扩展管道DSL时，通常意味着插件已经实现了一个新步骤。

 

pipeline syntax:

 

pipeline is Declarative Pipeline-specific syntax that defines a "block" containing all content and instructions for executing the entire Pipeline.

agent is Declarative Pipeline-specific syntax that instructs Jenkins to allocate an executor (on a node) and workspace for the entire Pipeline.

stage is a syntax block that describes a stage of this Pipeline. Read more about stage blocks in Declarative Pipeline syntax on the Pipeline syntax page. As mentioned above, stage blocks are optional in Scripted Pipeline syntax.

steps is Declarative Pipeline-specific syntax that describes the steps to be run in this stage.

sh is a Pipeline step (provided by the Pipeline: Nodes and Processes plugin) that executes the given shell command.

junit is another a Pipeline step (provided by the JUnit plugin) for aggregating test reports.

node is Scripted Pipeline-specific syntax that instructs Jenkins to execute this Pipeline (and any stages contained within it), on any available agent/node. This is effectively equivalent to agent in Declarative Pipeline-specific syntax.
