DEVOPS: What is the Jenkinsfile?๐Ÿ’ก

ยท devops

It is a text file which defines a Jenkins Pipeline.โš™

The Jenkinsfile can be committed to a projectโ€™s source control repository.

This is the foundation of "Pipeline-as-code";

Treating the CD pipeline a part of the application to be versioned and reviewed like any other code.๐Ÿ‘จโ€๐Ÿ’ป

โ€•Automatically creates a Pipeline build process for all branches and pull requests.

โ€•Code review/iteration on the Pipeline (along with the remaining source code).

โ€•Audit trail for the Pipeline.

โ€•Single source of truth for the Pipeline, which can be viewed and edited by multiple members of the project.

While the syntax for defining a Pipeline, either in the web UI or with a Jenkinsfile is the same,

it is generally considered best practiceโœ… to define the Pipeline in a Jenkinsfile and check that in to source control.
