Setting up load balancer frontend with on GCP with Pulumi - google-cloud-platform

Question

Right now I'm learning how to setup a website served by a GCP bucket using Pulumi however, I've stuck at the last step exposing an IP address and attaching it to the LB. Everything looks good except This load balancer has no frontend configured
I think the ForwardingRule is what I need but it doesn't except the BucketBackend (see code and output below).
Any suggestions on how to move forward?

Answer 1

I was using the wrong fowarding rule class. Because of the LB setup regional forwarding was wrong.
# Forwarding rule for External Network Load Balancing using Backend Services
web_forward = gcp.compute.GlobalForwardingRule("webforward",
project="myproj",
port_range="443",
target=nbprod_target_https_proxy.self_link
)
