Jenkins was built by Kohsuke Kawaguchi in 2004 and is one of the most popular CI/CD tools for Continuous Integration and Continuous Delivery. Jenkins is a hub for automating the various aspects of the software development lifecycle which includes building, testing, and deploying the application. We can call Jenkins a pipeline orchestrator where the developer can manage the pipelines of the projects that they have been developed.
| Project / Job | A Project or a Job is a collection of configurable instructions used for building developed source code, testing, collecting artifacts, sending notifications in emails, deploying in required environments, and much more. |
| Pipelines | A Jenkins pipeline is set of instructions and build steps configured in Jenkins to run all the processes in multiple environments in various steps. |
| Build Executor Status | All the currently running builds/jobs are displayed in this section. |
| Build Queue Status | All the scheduled builds/jobs in a queue and are yet to run are displayed in this section of the home page. |
| Plugins | More than 1500 community-contributed plugins in Jenkins support building software varieties, automate tests, and deploy projects for production releases. |
| Master – Agent | Executes in remote parallel machines for shorter build and test running time using additional resources in the cloud. |
Continuous Integration (CI) our team members can automate project workflows and simplify the process of building, testing, and deployment of software to different stages in the environment. Here environments are nothing but Staging, Dev, Test, QA, SIT, UAT and Prod. Continuous Integration (CI) will improve communication, track changes, fix bugs, and reduce conflicts in the code.
Continuous Delivery (CD) in Agile methodology is a software delivery process of short iterations and releasing new functionality once, it is ready for release. CD involves the seamless and automated delivery of software in a small and incremental way. The primary goal of continuous delivery is to enable frequent release of software into production rapidly and predictably aligned with the principles of agile methodologies.
