What Is Jenkins? Key Concepts, Architecture & Pros Cons
Content
Jenkins is opensource, you own your configuration, the pipelines and processes. Extend your Jenkins and integrate with multiple world-class third-party vendors into your software development pipelines. Jenkins supports the entire SDLC, including building, testing, documenting the software, and deploying. Jenkins is an open-source implementation of a Continuous Integration server written in Java. It streamlines multiple actions for Continuous Integration in a software project. Jenkins deploys the built application/executable to the test server, which can execute continuous, automated tests.
- Jenkins is a widely used application around the world that has around 300k installations and growing day by day.
- Jenkins is used by millions of users and thousands of companies.
- The plugin enables the selection of "Publish Javadoc" as a post-build action, specifying the directory where the Javadoc is to be gathered and if retention is expected for each successful build.
- Not easy to maintain it because it runs on a server and requires some skills as server administrator to monitor its activity.
- Groovy is a programming language based on the Java Virtual Machine.
- Jenkins increases code coverage which ultimately promotes a transparent development process among the team members.
When multiple teams share a server, there can be contention and bottlenecks. Concurrency in Jenkins requires planning and engineering consideration and is not automatically available out-of-the-box. Continuous Integration is a software development process where a code is continuously tested after a commit https://globalcloudteam.com/ to ensure there are no bugs. Jenkins is an open-source project that is entirely free to use. Jenkins has a vibrant development community that meets both in-person and online regularly. This simplifies installation while restricting resources to a single computer, virtual machine, or container.
Grant Jenkins access to the GitLab project
Complex pipelines, especially, can be difficult to code, debug and maintain. In both cases, automation reduces the number of errors that occur because the correct steps and best practices are encoded into Jenkins. Jenkins describes a desired state and the automation server ensures that that state is achieved. In addition, the velocity of releases can be increased since deployments are no longer bounded by personnel limitations, such as operator availability. Finally, Jenkins reduces stress on the development and operations team, by removing the need for middle of the night and weekend rollouts. 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.
Yes, Jenkins is the top open-source automation server with hundreds of plugins to build, deploy, and automate any development project. Jenkins offers various plugins to automate various development activities. It provides approximately 1,600 plugins that are spread across five different categories, namely platforms, UI, administration, source code management, and build management. Microservices is an architectural approach to software development. It composes a software application as a group of multiple loosely-coupled services. This type of approach is useful when you need to develop complex and extremely large software applications.
Jenkins Pipelines
Server security is achieved in the same way any other server is secured. Access to where it resides, such as a VM or bare metal server, is configured to allow for the fewest number of processes to communicate with the server. This is accomplished through typical server OS and networking security features. When you run Jenkins for the first time, it creates an administrative user with a long random password, which you can paste into its initial web page to unlock the installation. Around 2007 Hudson became known as a better alternative to Cruise Control and other open-source build-servers.
Jenkins is a popular CI tool that implements a continuous integration pipeline and can be created in Declarative Pipelines and Jenkins Job Builder. Codefresh is the most trusted GitOps platform for cloud-native apps. It’s built on Argo for declarative continuous delivery, making modern software delivery possible at enterprise scale.
Configure a Jenkins integration (recommended)
The communication activities include activity updates, the time these activities are triggered, and the usernames of the senders and recipients. Dispatching builds to the nodes/slaves for the actual execution. Not easy to maintain it because it runs on a server and requires some skills as server administrator to monitor its activity.
This allows the development teams to detect the problems early. Jenkins builds and tests our software projects which continuously making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build.

Easy Distribution
It is the only choice when you need more control over integration and testing. It is hard to configure and install but that is the trade-off for control over customization and configuration. Jenkins is free of cost itself although you need to server to host it. We use Jenkins only what is jenkins for projects which require more configuration and security. Jenkins is a well-known continuous integration tool developed initially by Hudson before it became available on the open-source market. Hudson was created by Kohsuke Kawaguchi in 2004 while working at Sun Microsystems .

What is Jenkins? The CI server explained
Jenkins X is useful regardless of your familiarity with Kubernetes, providing a CI/CD process to facilitate cloud migration. It supports bootstrapping onto your chosen cloud, which is crucial for a hybrid setup. For these reasons, many teams are transitioning away from Jenkins and adopting newer solutions that are more supportive of a containerized, microservices-oriented DevOps environment. Offers no functionality for real production deployments—“deploying with Jenkins” means running a fully customized set of scripts to handle the deployment. Jenkins sprawl—this is a common problem which also stems from lack of federation. Multiple teams using Jenkins can create a large number of standalone Jenkins servers that are difficult to manage.
