  • The parameterDefinitions section defines which parameters are exposed in the pipeline template. Multiple parameter types are supported, such as booleans, drop-down lists, credentials, passwords, and text.
  • The jenkinsfileTemplate section defines a jenkinsfile for the Jenkins pipeline and can reference the parameters exposed in parameterDefinitions part.
