For DevOps experts and newcomers alike, Jenkins CI/CD has long been the go-to solution. On GitHub, it has more than 16,000 ratings and 6,500 forks. Jenkins, one of the pioneers in the CI/CD market, has a large user base and more than 1500 plugins to assist professionals ship via their Jenkins Pipelines more quickly.
You’ve come to the perfect place if you’re beginning your CI/CD adventure or want a quick refresher on Jenkins Pipeline.
All the information you require for Jenkins pipeline and Jenkins training will be provided in this article, along with a thorough explanation of the underlying ideas.
What is CI?
The CI tool runs a code test as soon as the code is committed and the software build process is successfully finished. The CI tool deploys the code and pushes it into the production process if the test is successful. The term “Continuous Integration” refers to the continuous process of committing, building, testing, and deploying that occurs in software development.
What is Jenkins?
A succession of events is orchestrated by Jenkins, an open-source Continuous Integration server built on Java, to finish the process automatically. All stages of the software development life cycle, such as building, testing, documenting, deploying, and other stages, are supported by Jenkins. Because it is a server-based application, a web server like Apache Tomcat is needed. Jenkins software’s ability to track recurring tasks that come up while a project is being developed is what made it so popular. For instance, if your team is working on a project, Jenkins will continuously test your project builds and let you know if there are any mistakes at the beginning of the process.
What is Jenkins Pipeline?
A pipeline is an ordered sequence of events or actions that are related within the Jenkins CI/CD framework. Jenkins pipeline, to put it simply, is a group of plugins or modules that allow Jenkins to implement and integrate Continuous Delivery pipelines. Through the usage of the pipeline’s Domain-Specific Language (DSL), the Jenkins pipeline offers an extendable automation system for creating simple or intricate “template” distribution pipelines. In the Jenkins pipeline, Continuous Delivery exists in four states:
Why use Jenkins Pipeline?
Jenkins CI/CD is crucial for producing high-quality apps or products, as was previously stated in this tutorial on the Jenkins pipeline. Now that Jenkins has demonstrated its expertise in continuous integration, continuous testing, and continuous delivery, we are aware of this. It makes use of a tool called Jenkins pipeline for Continuous Delivery, which essentially allows for the periodic delivery of software. The program is always ready for production, thanks to this method.
Jenkins is a continuous integration tool; therefore, it generates build jobs to carry out a variety of activities in various stages. It is challenging to accomplish this in a company with numerous teams and projects if you use a single server. Most frequently, it will result in server overload, which will cause bottlenecks in the software development process, which is a big no-no in our book. Jenkins distributes all of the work it receives among its slaves to ensure that such a situation does not arise. Thus, Jenkins employs a master-slave architecture in which a single Jenkins server serves as the master from which all jobs are dispersed to many slaves. These slaves, which carry out duties based on the setups, can also be referred to as agents.
How does Jenkins work?
Jenkins enables the creation of build Jobs. Build Jobs are operations that let you set up a series of software development procedures to assist in the creation of your software.
These build jobs can be configured in an infinite number of different ways.
What kind of work you wish to do is also up to you. Jenkins lets you select from a variety of project types, including:
- Freestyle Project- This gives you a lot of configuration and freedom, and you can even use it to perform non-software development processes.
- Pipeline- This feature enables you to build a pipeline that will carry out a series of phases that can each contain a number of different sets of commands. When building the software development pipeline, this is helpful.
- Multi-configuration Project- This is for projects when you want to configure the software development process in a very big number of different ways. A multi-branch pipeline is useful when you have a large number of projects that you wish to develop, configure, and deploy simultaneously. It enables you to establish many pipelines concurrently.
- Folder- This is only an object that enables you to organize all of your stuff into user-defined categories and to group related items together.
- GitHub Organization- With this, you can search a company’s repository for all of its software and markets.
Advantages of using Jenkins
- A fairly transparent community controls Jenkins. They offer open forums once a month where they solicit suggestions from the general public for the advancement of the Jenkins project.
- The project has so far resolved over 280 tickets, and stable releases are released every three months.
- Jenkins advances along with technology. Jenkins’ plugins database now has about 320 plugins that have been published. Jenkins gains even more power and functionality with plugins.
- You can deploy the Jenkins tool on cloud-based platforms because it also supports cloud-based architecture.
- Jenkins’ success can be attributed to the fact that developers developed it for developers.
That was Jenkins, a stunning solution that enables us to integrate all the many aspects of our software development processes and automate many of them. It is entirely free and has a sizable user base.
A well-defined Jenkins pipeline can speed up production and enhance application quality. It gives your current building, committing, automated testing, and deployment processes a clear framework.
With the support of an online Selenium grid-like LambdaTest, this Jenkins pipeline lesson enables you to build your first Jenkins pipeline and implement automation testing successfully.
