Jenkins on-prem / bare metal with no cloud

Hello everyone.

I have set up a test k8s rancher cluster, and everything works fine. However, I am now trying to follow the tutorial on how to set Jenkins up along with Rancher, and have gotten to a point in which a Cloud server is needed. I am unable to use any cloud provider for the project I am working on, so I wondered if there was any way I could install the Jenkins Plugin without any external Cloud Provider.

Thanks in advance!
