How good it would be that before stepping into something, you could already know if that will work for you? Mr. Kawaguchi also had the same thought. And this gave rise to jenkins. This article will take you through what is Jenkins pipeline while explaining the history of jenkins.
History of Jenkins:
This inquisitiveness led to the creation of Hudson, an automation server. A notorious disagreement erupted in 2011 between the independent Hudson open source community and Oracle, which now includes Sun Microsystems.
This squabble resulted in the creation of Jenkins, a fork. Jenkins and Hudson were both around for a long period, although Jenkins was the more popular option. In January 2020, the Hudson project came to an end. Jenkins is still going strong.
Kawaguchi worked on a number of development projects and hated breaking builds when code failed. As a result, he began looking for a qa tools that could assist him in determining whether the code would work before committing it to the repository.
What is Jenkins?
Jenkins is a continuous integration automation technology used by DevOps teams. It’s a Java-based open-source programme. Throughout the software development lifecycle, it is used.
This applies not only to development and testing but also to deployment. It makes it considerably easier for developers to make updates to their projects. Jenkins can also be used to deliver software projects in a continuous fashion.
What is Jenkins Pipeline?
A Jenkins Pipeline is a series of jobs, tasks, or events that are linked together in a logical order. In other words, it’s a collection of plugins that make it simple to integrate and deploy continuous delivery pipelines. Extendable automation is used to assist a pipeline in the design of both sophisticated and basic delivery pipelines using code and a domain-specific language. Let’s take a look at continuous delivery pipelines and how they work presently. The primary feature of a Jenkins pipeline is that each event, task, or job it contains is dependent on one or more of these events, jobs, or tasks in some way. Build, test, deploy, and release are all states in a continuous delivery pipeline. All of these states are interconnected.
A continuous delivery pipeline is a series of events that occur in each of these states. It’s a script that performs the steps necessary to obtain version control software. Before the software is launched, all changes to it must go through a series of rigorous processes. This approach also assures that the software is developed in a repeatable and dependable manner, as well as involving several testing and deployment stages as the software develops.
JenkinsFile is a text file that contains Jenkins pipeline definitions. JenkinsFile is frequently used to create pipelines as code, and the complete process is defined in DSL. You may also use the JenkinsFile to keep track of the steps required to run Jenkins pipelines. Some of the advantages of using JenkinsFile are listed below:
- It makes it simple to review the code in the pipeline.
- It can assist you in executing pull requests for all of the pipelines you’ve developed for various branches.
- It’s the only place where you can modify your pipelines, and it’s the only place where you can do so.
- It can assist you in performing a Jenkins pipeline audit.
JenkinsFile is defined using two types of syntax:
-
Declarative pipelines syntax:
Using this approach, creating pipelines is a lot easier. It has a well-defined hierarchy that aids in the creation of pipelines. It provides you with basic controls over every aspect of pipeline execution.
-
Scripted pipeline syntax:
It operates on Jenkins master and utilizes a lightweight executor. It has its own resources for converting pipelines into atomic commands. Both of these syntaxes are clearly distinct from one another, as evidenced by their definitions. Not only that but they’re also characterized in a variety of ways.
