I have two kubernetes clusters, one in Google Cloud Platform over GKE and one in Amazon Web Services built using Kops.

How do I implement multi cluster communication between a pod in AWS Kops Cluster and a pod in GKE ?

My Kops cluster uses flannel-vxlan mode of networking, hence there are no routes in the route table on the AWS side. So creating a VPC level VPN tunnel is not helpful. I need to achieve a VPN tunnel between the Kubernetes clusters and manage the routes.

Please advise me as to how I can achieve this.
