If you are going to use a GKE Gateway API you can take as a reference the following enabling steps:

1. In GCloud console select the project of GKE cluster

gcloud config set project PROJECT_ID

2. Enable Gateway Controller in you existing GKE cluster

gcloud container clusters update CLUSTER_NAME \
    --location=CLUSTER_LOCATION \
    --gateway-api=standard

3. Log in to the GKE cluster as user kubeadmin

gcloud container clusters get-credentials CLUSTER_NAME \
    --zone CLUSTER_LOCATION

4. Apply the following YAML containing the GatewayClass and a Self-Signed SSL certificate
