Continuous delivery -pipeline getting started

Pipeline yes Jenkins2.X The core characteristics of , help Jenkins from CI To CD And DevOps The transformation of .

Pipeline It's a set of plug-ins , Give Way Jenkins It can realize the landing and implementation of continuous delivery pipeline . Continuous delivery pipeline （CD
Pipeline） It is an automatic representation of the whole process from version control to delivery to users or customers . Every change in the software （ Submit to source control system ） It takes a complex process to be released .

Pipeline Provides a set of extensible tools , adopt Pipeline Domain Specific Language（DSL）syntax You can achieve
Pipeline as Code（ Jenkinsfile Stored in the project's source code library ） Purpose .

Pipeline The basic concepts in

Stage

Stage , One Pipeline It can be divided into several Stage, Every Stage Represents a group of operations , for example ：“Build”,“Test”,“Deploy”.Stage
It's a concept of logical grouping , It can span multiple Node

Node

node , One Node It's just one. Jenkins node , Or is it Master, Or is it Agent, Is to perform Step The specific operating environment .

Steps

step ,Steps Is the most basic unit of operation , Small enough to create a directory , Big enough to build a Docker Mirror image .

Pipeline Create and configure

Create a new one Jenkins Mission , In the task type, select Pipeline. take Pipleline Fill in the task code of Pipeline Script Dialog box .

function Pipeline Mission .

Run through the code base Pipeline Mission

Except that it can be directly in Jenkins UI Add Pipeline Code running tasks , You can also save the code to the code base , Then run by specifying the location of the code Pipeline
Mission . The operation steps are as follows ：

1. Create a new one Jenkins Mission , In the task type, select Pipeline.

2. stay Jenkins Pipeline Select... From the task Pipeline script from SCM, Then add git Source code address , stay Script Path Fill in the... To be run Jenkinsfile The address of the document .

3. Run through the code base Pipeline Mission .

Save pairs Pipeline Configuration made , Then run the task .

Pipeline, In short , It's a set that runs on Jenkins
Workflow framework on , Connect tasks that run independently of one or more nodes , Realize the complex process layout and visualization that single task is difficult to complete .
