Is it possible to connect a GKE cluster to a VPC within AWS? For this specific use case, I want the GKE cluster to be able to talk with the EKS cluster behind a VPC in AWS.
gcloud container clusters describe _cluster_name_ | grep clusterIpv4CidrDo I need to create a VPC for my GKE cluster in addition to the VPC for my EKS cluster, or do I just need the CIDR range for the GKE cluster for AWS?
Google searching renders very few results for connecting clusters from different providers.
In my opinion, it's possible with VPN connection. At first, I think you should have a look at Kubernetes Engine Communication Through VPN demo. And then, move to the more close example for your case - site-to-site VPN between GCP and AWS. In addition, check some Google Cloud Router documentation and example for some extra information about networking at GKE.
