What is Jenkins?
Jenkins is an open source automation server written in Java and designed with a clear goal: to facilitate continuous integration (CI) and continuous delivery (CD).
Unlike other similar tools , Jenkins offers a large library of plugins that allows its integration with different technologies and tools, such as Git, Docker, and Kubernetes, providing great flexibility and extensibility compared to its competitors.
In fact, here we tell you something more compared to cron as an automation tool .
What is Jenkins used for?
Jenkins is used to automate the process of building, testing, croatia business email list and deploying applications . It allows developers to detect bugs early in the development cycle , which helps improve software quality and speed up delivery.
Additionally, Jenkins can manage deployments across different environments, as well as automate infrastructure as code.
How does Jenkins work?
Now that you understand what Jenkins is and what it is used for, you may be interested to know that how Jenkins works is very easy to understand. This software has a main server architecture and slave nodes that allow the distribution of jobs across different machines.
Jobs: A job in Jenkins is an individual task, such as building an application or running tests.
Pipelines: These elements define a set of stages for building, testing and deploying code, allowing automation of the entire workflow.
Plugins: Jenkins has a wide variety of plugins that extend its functionality and integrate different tools and platforms.
For example, this would be how to configure a pipeline with Jenkins :
Create a new pipeline in Jenkins.
Write a 'Jenkinsfile' with build, test and deployment stages.
Set up the code repository and necessary credentials.
Run the pipeline and monitor progress in the Jenkins interface.
Key Features of Jenkins
Jenkins stands out for features like these:
Jenkins can be integrated with almost any development and deployment tool thanks to its more than 1,500 plugins.
It easily integrates with Git, Docker, Kubernetes and many other platforms .
It enables infrastructure automation through IaC , integration with tools such as Ansible and Puppet, and management of servers and containers.
You already know what Jenkins is and how it works, so how about we dig a little deeper into the topic?
Advantages and disadvantages of using Jenkins
While Jenkins is a great tool for continuous integration and delivery, it is not without certain limitations, so it is important to know its pros and cons before you start using it!
Among its main advantages , we find that Jenkins has a huge variety of plugins that allow you to customize and extend its functionality, that it has a large community and that it supports integrations with many other tools and platforms.
In the disadvantages section , it is worth noting that its user interface has become somewhat obsolete, that it perhaps has too many plugins and that can be somewhat complicated to manage, and that using it requires technical knowledge that not all users have.
Initial Jenkins Setup
The initial configuration of Jenkins is relatively simple and can be completed in just a few steps.
Download Jenkins from its official website and download the WAR file or installer corresponding to the operating system you are using.
Run the downloaded file . If you have opted for the WAR file, you can launch it using the java command '-jar jenkins.war --httpPort=8080'.
Access Jenkins by entering 'http://localhost:8080' in your web browser. After that, just follow the installation instructions.
Install the required plugins for your project from the Jenkins admin panel.
All you need to do now is create a new project . To set it up, select its type (freestyle, pipeline…) and configure the code repositories and build stages.
And now that you know what Jenkins is and how to use it to your advantage, don't forget that we make it easy for you with our free Website Builder , as well as quality web hosting for any type of online project!
