Therefore, all cloud applications are handled by various automation tools and services. Jenkins Pipeline is one of them that helps in software development automation. In this blog, we will learn to create CI CD Pipeline using Jenkins. Jenkins Pipeline (or simply “Pipeline” with a capital “P”) is a suite of plugins
which supports implementing and integrating continuous delivery pipelines into
Jenkins.
As you know it is an open-source project with an abundant plugin ecosystem, all of the plugins and features are intelligently supported by a vast community contribution. The amazing community involvement that accompanies Jenkins is one of the major reasons that have helped with its maturity. The setup and configuration procedures of this tool are quite easy, as only some steps are needed in the installation. The upgrading procedure of Jenkins is also trouble-free and straight-forward.

Using similar types of steps, different kinds of automation pipelines can be configured. When both these practices come together, all the steps are considered automated, resulting in the process we know as CI/CD. Implementation of CI/CD enables the team to deploy codes quickly and efficiently. In the world of DevOps, professionals frequently work with pipelines. Pipelines automatically build and test code projects to make them available to others, and work with just about any programming language or project type. Many tutorials delay the introduction of the Groovy or Kotlin based Jenkins pipeline and instead concentrate on the GUI tools used to create standard build jobs.
The screenshot below shows the configuration web form for a multibranch pipeline. Jenkins is distributed as a WAR archive and as installer packages for the major operating systems, as a Homebrew package, as a Docker image, and as source code. The source code is mostly https://www.globalcloudteam.com/ Java, with a few Groovy, Ruby, and Antlr files. Let’s consider a scenario where the complete source code of the application was built and then deployed on test server for testing. It sounds like a perfect way to develop software, but this process has many problems.

With a pipeline, developers can build an IDE in 20 minutes or less and get their code into an IDE optimized to run on modern OSs. For many teams engaging in a DevOps transition, the inclusion of Jenkins plugins in their builds is the first step in a gradual operational shift left. Jenkins works with multiple programming languages and can run on multiple platforms (Windows, Linux, and macOS). It also has vast community support, and there are many plugins available for integrating it with other tools like Slack, GitHub, Docker.
The challenges of continuous integration are primarily around team adoption and initial technical installation. If a team doesn’t currently have a CI solution in place, it can require some effort to pick one and get started. Thus, considerations need to be made around the existing engineering infrastructure when installing a CI pipeline. CI helps to scale up headcount and delivery output of engineering teams. Introducing CI to the aforementioned scenario allows software developers to work independently on features in parallel.
DevOps CI/CD Project Jenkins Shared Lib
But if all of the unit tests pass, the build process can move on to the integration tests, which take longer to complete. It’s used to implement Continuous Integration (CI) and Continuous Delivery (CD) for any development project. Jenkins is a widely used application around the world that has around 300k installations and growing day by day. By using Jenkins, software companies can accelerate their software development process, as Jenkins can automate build and test at a rapid rate.
This concept was first introduced over two decades ago to avoid “integration hell,” which happens when integration is put off till the end of a project. CI improves overall engineering communication and accountability, which enables greater collaboration between development and operations in a DevOps team. By introducing pull request workflows tied to CI, developers gain passive knowledge what is jenkins ci share. Pull requests allow developers to observe and comment on code from other team members. Developers can now view and collaborate on feature branches with other developers as the features progress through the CI Pipeline. An efficient CI pipeline with high-confidence automated test coverage will safeguard from regressions and ensure that new features match a specification.
Which CI/CD platform should you choose?
Checking a Jenkinsfile into a source control tool allows the whole team to edit, review, and adapt the steps in the delivery pipeline. The program runs web containers and plugins, such as Apache Tomcat, and helps manage lifecycle and access rights requests. Over 1700 plugins for Jenkins enrich the software integration, automation, and delivery processes and provide a customizable environment. The developer Kohsuke Kawaguchi, who worked at Sun systems, wanted to create a method to perform continuous integration.
A number of key contributors to the Jenkins project are employed by CloudBees. In support of the community, CloudBees is the lead sponsor of DevOps World | Jenkins World, the annual user conference for the Jenkins community. Jenkins World enables the community to gather together, fosters a sense of community, allows users to learn from each other and supports community growth.

Jenkins offers various build jobs by default, and more are available through plugins. The idea proved successful and quickly spread to the rest of his team. As a result, Kohsuke Kawaguch created the Jenkins project and open-sourced the program.
- There are lots of other resources available on the Internet that can help you further understand pipelines.
- Simplilearn also offers courses and programs that will improve your skills with pipelines and other DevOps tools and platforms.
- You will soon be able to see that all the segments of the pipeline are completed.
- The pull request notifies other developers of the new set of changes that are ready for integration.
- Continuous integration covers the process of multiple developers attempting to merge their code changes with the main code repository of a project.
The Jenkins CI server can be run as a standalone application with a built-in Java servlet container, or as a servlet in other Java servlet containers such as Apache Tomcat. CI/CD, a key component of a DevOps strategy, allows you to shorten the development lifecycle while maintaining quality by automating tasks like testing. In short, a successful implementation will help you test more often and deploy faster with high quality. If the build fails, then Jenkins will notify the errors to the developer team. Let us imagine, that there are around 10 developers who are working on a shared repository.

With Azure DevOps, you get Azure Boards, Azure Repos, Azure Pipelines, Azure Test Plans and Azure Artifacts. CI CD Pipelines in DevOps enable an organization in the faster and more effective delivery of software products. In this blog, we have created a Virtual Machine in Azure and followed all the steps to create CI CD pipeline using Jenkins. We used Tomcat as our container service and deployed our simple web app via Jenkins. Step 6) If you want to check the war file created in the previous steps, visit the workspace on your Jenkins dashboard or just run the directory commands in your server.
