Jenkins

Jenkins is an open source automation platform designed for continuous integration purposes. This tool is written in Java and has many plugins. You can use Jenkins to build and test software projects continuously, and continuously deliver digital projects by integrating multiple testing and deployment technologies.

With more than 147,000 active installations and more than 1 million users around the world, Jenkins has been one of the most popular DevOps tools. It was created for developers with one purpose in mind: to become the best build automation server. The tool is free and open source. It helps DevOps automate the parts of software development related to building, testing, deploying, static analysis, and facilitating the CI/CD pipeline. Jenkins is very useful if you want to accelerate the software development process through automation. It can be used both as a simple CI server, and as the CD hub for any project. The tool provides multiple plugins (over 1,000) to integrate with test automation software and frameworks. 

Jenkins features 

Every time a developer commits their code to the code repository, Jenkins responds to any changes and takes predefined actions—e.g., running tests or performing static code analysis. The user is immediately notified of the errors if the build fails. Therefore, errors and bugs can be fixed in no time. In the event there are no errors, and the build is successful, the code is automatically moved to a ‘release-ready’ environment and the user is notified. 

Why use Jenkins?

Jenkins is a free tool with great community support – it’s extremely easy to find tutorials and other resources to get the most out of it. It is intuitive and relatively easy to install because the server was developed as a self-contained program. It is built in Java and hence it is portable to all the major platforms. Jenkins is probably one of the best tools for those who want to improve the development life cycle by automating building, testing, and deployment of software. The more than 1,000 plugins further extend Jenkins’s functionality. On the other hand, if a plugin doesn’t exist, you can just code it and share it with the Jenkins community. Finally, the server uses a master-slave architecture to manage distributed builds. The ‘master’ (which is the name of the main server) can distribute workload to the ‘slave’ servers. This enables you to simultaneously run multiple builds and test environments.

What is CI/CD — all you need to know

The CI/CD process is now one of the essential paradigms in modern software development, oriented on delivery and quality. Continuous integration, continuous delivery, and continuous deployment benefit both software development and business. But what exactly stands behind the acronym CI/CD, and what is its added value? CI/CD stands for Continuous Integration (CI) and Continuous Deployment or Continuous Delivery (CD). Although the basics of each are relatively similar, there are fundamental differences that define the key beneficiaries, and the results that can be achieved.

How to set up and optimize a CI/CD pipeline

Nowadays you will hear that if you want your SDLC (Software Development Lifecycle) to be efficient, you need to have a proper, well-established CI/CD setup. In most cases, it’s true. In this blog post I am going to focus on how to go about creating such a setup when creating a new CI/CD pipeline and optimizing an existing one. I will also look at best practices to follow and outline errors to avoid. Finally, I will analyze the possible reasons why your CI/CD setup may not work as expected and propose solutions to turn things around.

CI/CD pipeline: why it makes sense for your startup

Today, the world of software and app development evolves rapidly. Both startups and larger companies keep bringing more and faster enhancements and functionality to the market to stay ahead of the competition. In order to maintain the pace of development and increase efficiency, development teams need to constantly optimize their workflow. One of the methods to both develop and sustain business reliability is the implementation of a CI/CD pipeline. It is now one of the fundamental practices for DevOps implementation in startups and one of the best practices that allow DevOps teams to deliver code more frequently and reliably.
