5. What is the Jenkins pipeline?

Once set up is done for Jenkins, you'll need to establish some projects for Jenkins to work on. While you can construct scripts using the web UI, the current best practice is to write a Jenkinsfile pipeline script and check it into your repository.

A Jenkins Pipeline is a series of jobs, tasks, or events that are linked together in a logical order. In other words, it's a collection of plugins that make it simple to integrate and deploy continuous delivery pipelines. Extendable automation is used to assist a pipeline in the design of both sophisticated and basic delivery pipelines using code and a domain-specific language (DSL).

A Jenkins Pipeline's definition is often written into a text file (known as a Jenkinsfile), which is then checked into a project's source control repository. The Benefits of using JenkinsFile are mentioned below.

1. It is easy to review the code in the pipeline.

2. It can assist in executing pull requests for all of the pipelines you've developed for various branches.

3. It's the only place where one can modify pipelines.

4. It can assist you in performing a Jenkins pipeline audit.
