I am trialling a new cluster deployment using Istio on GKE for an upcoming project. I have reserved an external regional static IP on GCP.
I have an A record forwarded from a subdomain to this IP address. When creating my
ingressgateway I would like to be able to provide this external IP within my template so that the new cluster uses the existing reserved IP.
I can convert an auto assigned ephermeral IP to static, but that requires updating the A record which is slow and is simply not suitable.
Is it possible to assign the reserved IP with a
networking.istio.io/v1alpha3 and if so, how?
Apologies if this is simple, I’m new to this. Thanks!
