Therefore:Ī Jenkins pipeline is the way to execute a Jenkins job sequentially in a defined way by codifying it and structuring it inside multiple blocks that can include multiple steps containing tasks. Note that some commands, like java, javac, and mvn, are not available by default, and they need to be installed and configured through Jenkins. It's easy to see the structure of a Jenkins pipeline from this sample script. And next stages if you want to define further.

List the files in current directory path by executing a default shell command This requires Apache Maven configuration from Jenkins Executes the Apache Maven commands, clean then package. This requires JDK configuration from Jenkins Execute the compiled Java binary called HelloWorld. This requires JDKconfiguration from Jenkins Just print a Hello, Pipeline to the console Here is an example of a simple Jenkins pipeline file. The Jenkins pipeline is provided as a codified script typically called a Jenkinsfile, although the file name can be different. 'Step' simply says what to execute, and this can be a simple print command (e.g., echo 'Hello, World'), a program-execution command (e.g., java HelloWorld), a shell-execution command (e.g., chmod 755 Hello), or any other command-as long as it is recognized as an executable command through the Jenkins environment. In the example diagram above, Stage 1 can be named 'Build,' 'Gather Information,' or whatever, and a similar idea is applied for the other stage blocks. A stage block can be named anything it is used to visualize the pipeline process.

Stage: A block that contains a series of steps.Here, you should see two familiar concepts: Stage and Step. The easiest way to understand a pipeline is to visualize a sequence of stages, like this: On its own, Jenkins does not perform any functionality but gets more and more powerful as other tools are plugged into it.Ī pipeline is a separate concept that refers to the groups of events or jobs that are connected together in a sequence:Ī pipeline is a sequence of events or jobs that can be executed. to plug into Jenkins, and it executes and automates the tasks.

Jenkins offers a way for other application APIs, software libraries, build tools, etc. What happens when you do click a button depends on what the remote is built to control. Think about Jenkins like a remote control-it's the place you click a button. To start, it is helpful to know that Jenkins itself is not a pipeline. Just creating a new Jenkins job does not construct a pipeline. What is a pipeline?īefore jumping into the tutorial, it's helpful to know something about CI/CD pipelines. In this article, I will share a step-by-step walkthrough on how you can build a CI/CD pipeline using Jenkins. And the open source version of Jenkins was the obvious choice due to its flexibility, openness, powerful plugin-capabilities, and ease of use. This is the reason we decided to build a CI/CD pipeline for DevOps. The development environment was still very manual, and our team needed to automate it to gain as much flexibility as possible while accelerating the development effort. The core technology driving that initiative was Jenkins, an open source tool to build continuous integration and continuous delivery (CI/CD) pipelines.Īt Citi, there was a separate team that provided dedicated Jenkins pipelines with a stable master-slave node setup, but the environment was only used for quality assurance (QA), staging, and production environments.

In my article A beginner's guide to building DevOps pipelines with open source tools, I shared a story about building a DevOps pipeline from scratch.
