Jenkins Pipeline Environment Variables

In this article, I will introduce ways of define and using variables in the pipelines. Read the previous part if you didn’t yet. Variables are the most important part of the pipelines that able us to making repeatable pipelines and separating codes from configurations. That is why you should learn how to define and use variables. So, let’s get started.

Jenkins Is Getting Old — It’s Time to Move On

By far, Jenkins is the most adopted tool for continuous integration, owning nearly 50% of the market share. As so many developers are using it, it has excellent community support, like no other Jenkins alternative. With that, it has more than 1,500 plugins available for continuous integration and delivery purposes.

We love and respect Jenkins. After all, it’s the first tool we encountered at the beginning of our automation careers. But as things are rapidly changing in the automation field, Jenkins is** left behind with his old approach**. Even though many developers and companies are using it, most of them aren’t happy with it. Having used it ourselves on previous projects, we quickly became frustrated by its lack of functionality, numerous maintenance issues, dependencies, and scaling problems.

We decided to investigate if other developers face the same problems and quickly saw the need to create a tool ourselves. We asked some developers at last year’s AWS Summit in Berlin about this. Most of them told us that they chose Jenkins because it’s free in the first place. However, many of them expressed interest in trying to use some other Jenkins alternative.

How To Set Jenkins Pipeline Environment Variables?

Jenkins is an open-source and extensible continuous integration and continuous deployment server. It is used to automate the process of continuous integration and continuous deployment(CI/CD). The importance of monitoring remote jobs and interacting with team members for stable code is immense; Jenkins takes care of all these requirements and allows a smooth integration via plugins, pipelines, and Jenkins environment variables.

If you are amongst the typical Jenkins users who want to add to their knowledge about CI and CD, some fundamental concepts must be learned. In this article, we will learn about the critical concept of Jenkins pipeline environment variables. We will also view and install the Lambatest Jenkins plugin and use the in-build variables from the Jenkins environment variables list.

Continuous Delivery Pipelines with Jenkins 2.0

Within our engineering team, we build, test and deploy mobile, web and embedded applications targeting a wide variety of platforms and to do so we primarly use Jenkins for continuous integration and deployment. While Jenkins may not always be the prettiest or most user-friendly tool out there, it’s extremely flexible and thanks to the huge open source community behind the project there are very few configurations that cannot be supported out of the box. Plus there’s also an extensive API should the need arise to create custom plugins or tool integrations.

The recent Jenkins 2.0 release brings some interesting new features but the one we’re most excited about is delivery pipelines and an extensible Groovy-based Domain Specific Language (DSL) which enables us to model a “pipeline as code” by versioning a Jenkinsfile along with our source. However, pipelines in Jenkins are not a new concept, they’ve been around for a year or two under the name of workflows but with the 2.0 release this functionality becomes part of the key offering and it very much feels like this will be the future of how we manage builds in Jenkins.

Jenkins — How Can We Get Started Jobs in Jenkins (Part 3)

In the previous article, we learned how to create Users + Manage + Assign Roles in Jenkins. In this article, I will be highlighting how can we create some basic JOBS in Jenkins. Furthermore, these are the points which I am going to explain.

• How to create a basic Job in Jenkins.
• Basic Job Configurations.
• How to run the Job remotely.
• How to chain Job Execution

How to create a basic Job in Jenkins?

First of all **click **on New Item on the Jenkins Dashboard. Then Give a name to your project. Then you can select a **Freestyle **or **Multi-configuration **project. For this tutorial please go with the Freestyle project. Then click on the **Okay **button.

As soon as you complete these simple steps you will be taken to the **configuration **window. Here you can provide different details about Jobs. There are 5 sections available. **General, Source Code Management, Build Triggers, Build, **and Post-build Actions.

General Section

Here you can provide a quick description of your project or Job. You can preview it also. You can also use HTML tags inside the description.

Source Code Management Section

So here in case you want to take the build from any source code system like Git, Bitbucket, or any other source code management portals. We need to add plugins to those source code repositories. But in the coming tutorials, we will see how exactly we can get our build and trigger our Job from a source code management system.

Jenkins Pipeline - Different types of CI pipelines and stages

We know that Jenkins is widely used as a Continuous Integration tool across the industry and provides great ease in automating the delivery pipeline. Moreover, we have already understood what Jenkins is? and how we may use it in our previous articles. Now we will go a step ahead and understand what a Jenkins pipeline is? Subsequently, we will dive through its concepts and learn to run a Jenkins Pipeline in this article. The basic concepts that we will cover are:

• What is Jenkins Pipeline?
• Why use Jenkins Pipeline?
• What is Jenkinsfile?
• Understanding Jenkinsfile syntax.
• Understanding Key constructs of Jenkinsfile.
• How to create Jenkins Pipeline?
• How to create a Scripted Jenkins Pipeline?
• And, how to create a Declarative Jenkins Pipeline?

What is Jenkins Pipeline?

In simple words, a pipeline is a set of interconnected tasks that execute in a specific order. Additionally, Jenkins Pipeline is a suite of plugins that help users implement and integrate continuous delivery pipelines into Jenkins. Moreover, using Pipeline, you can create complex or straightforward delivery pipelines as code via the Pipeline domain-specific language(DSL) syntax. Subsequently, the below states represent a continuous delivery Pipeline: –
