How to access via http to a cloud node deployed by jenkins

Jenkins setup:

Hello, i have configured kubernetes in jenkins using the kubernetes plugin, I am able to create dynamically nodes using a Pod template, nevertheless these pods are not reachable from external servers at least that they have some sort of kubernetes user, I am constrained to not do that, instead of that I wanted to set up a deployment with an ingress to expose one port of the cloud node, but I can not pass multiple files to the kubernetes plugin in the jenkins pipeline, how can I work this around without using a kubernetes user with high level of access?
