Demonstration how to use the newly introduced https redirect support in native GKE ingress resources (GCLB).
These files accompany my medium article At last: Redirect http to https in GKE ingress.
As mentioned in the article, your GKE cluster needs to be running at least a recent version 1.17-gke for this to work.
You will need a static reserved ip address going by the name of gke-https-redirect. Create it like this:
gcloud compute addresses create gke-https-redirect --global
You will want to override the domain names listed in managedcertificate.yaml. Also make sure they exist and point to the IP adress you created above.
