Enhance your CI/CD pipeline with expert Jenkins developers! Find talent skilled in automating builds, tests, and deployments for streamlined development.
The current technological scenario demands speed, precision and constant innovation. This means that developers working to satisfy these demands must constantly look for ways to automate aspects of their jobs that are a little more repetitive and don't require constant human involvement.
One tool that developers use to make continuous integration and continuous delivery and/or deployment a reality is Jenkins, an open source server written in Java. Jenkins implements these delivery workflows, also known as pipelines, throughout the software development lifecycle to accelerate the process in an automated way.
From building, testing, documenting and eventually deploying a software project, Jenkins supports developers by orchestrating a chain of actions to achieve the Continuous Integration process. Currently, Jenkins boasts well over 200,000 installations and continues to grow in popularity day by day.
In this article you will learn, among other things, how to hire Jenkins developers .
Hiring Guide
Companies and software developers choose to work with Jenkins as it helps speed up the software development process thanks to the server's ability to build and test at a rapid pace. As a server-based application, Jenkins requires a web server to implement workflows or pipelines. Pipelines help developers by automating testing and reporting on individual changes across a large code base in real time.
Jenkins pipelines make it easy to integrate disparate code branches into the main branch. It also has the ability to quickly detect defects in the codebase, build the software, automate the necessary build tests, prepare the codebase for deployment, and eventually deploy the code to containers and virtual machines. When implemented, Jenkins continuously tests project builds and displays errors in the early stages of development to save resources.
Plugins help enhance the Jenkins system while expanding its capabilities and integrations with other software. Developers have the ability to download plugins from the Jenkins online plugin repository, which currently features over 1,500 plugins for a wide variety of common use cases. These plugins help with tasks such as integrating other developer tools into the environment, administering Jenkins, and managing build and source code.
One of the most common uses of plugins is the integration of continuous deployment and continuous integration sources and targets. This includes software version control systems, container runtime systems, as well as public and private cloud instances. These plugins are one of the many advantages of Jenkins.
The flexibility and customization available when using Jenkins, as well as its more mature age, make it one of the preferred options for developers looking for a way to manage continuous deployment and integration. It is a well-understood tool, with extensive documentation, a broad knowledge base, and a wide variety of community resources available.
Jenkins developers have been and will continue to be highly sought after in the development community. Companies looking to streamline processes while proactively identifying issues require Jenkins experts to help make the development process as smooth and effective as possible.
Interview Questions
What are the benefits of using Jenkins?
- Ability to cache build failures at the integration stage.
- It can generate automatic build report notification for each source code stage.
- Integrates with LDAP email server to notify developers of build report successes or failures.
- It helps developers achieve continuous integration and deployment in an agile, test-driven development environment.
- Enables easy bug tracking in the early stages of development to help prevent errors from deployment to production.
What is a Jenkins pipeline and what are the pipeline types?
A pipeline is a special type of Jenkins job that is essentially a sequence of automated steps controlled by a defined set of rules or logic. This then orchestrates long-running activities that sometimes span many construction agents. These pipelines, formerly known as workflows, help organize complex activities that are not easily achieved when working in a freer method.
Pipelines in Jenkins are either a declarative pipeline or a scripted pipeline. Declarative pipelines use a variety of generic, predefined build stages or steps (code snippets) to create work according to the specifics of a build or automation needs. Scripted pipelines allow custom definition of these steps or stages using Groovy syntax. This provides better control for developers while also allowing fine-tuning of execution levels.
What is the continuous integration process like in Jenkins?
Continuous integration is the practice of constantly integrating a developer's code changes into the main code branch and at the same time testing that code through automated means. The test results decide whether the change will actually be implemented or not.
When using Jenkins, the process generally looks like the following:
- The developer makes a change, followed by a commit or pull request to the feature or development branch.
- The source control management system generates necessary events.
- The specific plugins installed detect these events in the repository settings and are then used to trigger the build/dependent/test jobs in Jenkins.
- After the tests and dependent jobs are completed, the system applies the change/patch label according to the test status.
- If ready, the Continuous Deployment tool deploys the change to the main code branch.
