The goal is to get a project off the ground from just a simple domain to an application running a g RPC server accessible via grpc-web on GKE.
Clone the repository so you have access to each individual yaml file. https://github.com/projectcontour/contour/blob/9c14f3d4a7/examples/contour/README.md
There is only one line to add to make this work on GKE.
Copy the files /examples/contour
to a new directory eg :my-dir
