I have a current GKE that runs a Node JS/React application. My project is hosted on Github and I am currently using Jenkins for my CI/CD pipeline. I have recently heard about Jenkins X and am interested in trying to use it for my GKE cluster.

On the official docs / most tutorials I seen, it mostly describes how to set up Jenkins X on a new Kubernetes cluster and a new Github repo. I'm wondering what would be the best/easiest approach to integrate Jenkins X into my current GKE & Github repo.

Any help would be appreciated, thanks!
