Jenkins Pipeline Tutorial: How to Create JenkinsFile (Example)

What is Jenkins Pipeline?


Jenkins Pipeline is a blend of modules that upholds coordination and execution of persistent conveyance pipelines. It has an extensible robotization server to make straightforward and complex conveyance pipelines as code by means of pipeline DSL. A Pipeline is a gathering of occasions interlinked with one another in a succession.

What are Continuous Delivery Pipelines? How does it work?

In a Jenkins pipeline, each work or occasion has a reliance on no less than at least one occasion of some kind.


The image above addresses a persistent conveyance pipeline in Jenkins. It contains a gathering of states called to construct, send, test and delivery. These occasions are interlinked with one another. Each state has its occasions, which work in a grouping called a nonstop conveyance pipeline.


A ceaseless conveyance pipeline is a mechanized articulation to show your interaction for getting programming for rendition control. Hence, every change made in your product goes through various complex cycles en route to being delivered. It likewise includes fostering the product in a dependable and repeatable way, and movement of the fabricated programming through various phases of testing and organization.

Introduce Build Pipeline Plugin in Jenkins

With the form pipeline module, you can make a pipeline perspective on approaching and active positions, and make triggers that require manual mediation.

This is the way you can introduce the form pipeline module in your Jenkins:

Stage 1) The settings for the module can be viewed as under,

Oversee Jenkins > Manage Plugins.

Assuming you have previously introduced the module, it is displayed under the introduced tab.

In the event that you have previously introduced the module, it is displayed under the introduced tab.

Stage 2)

You will be approached to give a name to the pipeline view. We will refer to it as "Guru99 Pipeline" as long as necessary.

Select Build a pipeline view under choices

Click alright


Stage 3) On the following page, you will be requested additional subtleties to design your Jenkins pipeline. Simply acknowledge the default settings, and ensure you pick the main work under the settings.

Click on Apply and afterward OK.

Running a Pipeline construct

Stage 1) For running a pipeline construct, you really want to chain your positions first. For this, go to your most memorable work and tap on design.

Stage 2) Now, under Build Triggers, check the Build after different tasks are fabricated choice.

In this way, a chain for every one of your positions has been made.

Stage 3) Install the Build Pipeline view module on the off chance that you don't have it introduced as of now.

Stage 4) Go to your Jenkins dashboard and make a view by tapping on the "+" button. Select the Build Pipeline View choice and snap OK.

Stage 5) Under the Pipeline view arrangement, find Pipeline Flow.


Under Pipeline stream, select the underlying position to run. Presently pick the work which has chains to different positions, as displayed in Step 1 and Step 2.

Here we have chosen Guru99 Project 1 as the underlying position, bound to different positions. Thus, individually, the positions will run ready to go.


At the point when the Jenkins pipeline is running, you can really take a look at its status with the assistance of Red and Green superficial points of interest. Red means the pipeline has fizzled, while green demonstrates achievement.

In this Jenkins pipeline model, we see that the button is green. Consequently, the pipeline is fruitful.


Running Jenkins pipeline

Click on Run to run the Jenkins pipeline. It will look something like this:

In the Jenkins pipeline script model above, we are exhibiting a basic "helloworld.java" program. In any case, progressively projects, you will be liable for making and building complex pipelines in Jenkins. See underneath for an example pipeline view.

Best Practices utilizing Jenkins Pipeline:


Utilize the authentic Jenkins Pipeline

Foster your pipeline as a code

Any non-arrangement work in your pipeline ought to happen inside a phase block.

Any material work in a pipeline should be performed inside a hub block.

Try not to utilize input inside a hub block.

Never set climate factors with env worldwide variable

Enclose your contributions with a break
