k8s ingress gce multi domain and managed ssl

• Version gke 1.21.x
• GKE Dataplane V2 (Cilium + eBPF) is implemented without kube-proxy and does not rely on iptables for service routing. This removes a major bottleneck for scaling Kubernetes services in very large clusters
• The maximum number of rules for a URL map is 50. This means that you can specify a maximum of 50 rules in an Ingress
• Managed certificates support up to 100 non-wildcard domains, whereas self-managed certificates can support wildcards
• GKE clusters have a limit of 1000 nodes. When services are deployed with NEGs, there is no GKE node limit
