I have running kubernetes cluster in europe region and there are 4 nodes running in same region within cluster GCP, Now my requirement is i want 2 node in Asia region and other 2 node keep in europe, Is it possible to run node in multi region within cluster ? Or Can we setup node pool region wise to the cluster?
I am not talking about multi region cluster and cluster federation.
If you use GKE - then no, it is not possible to use nodes from different regions in single cluster. But it is possible to use several clusters and one Istio control plane. Read more here: https://istio.io/docs/concepts/multicluster-deployments
If you are using vanilla Kubernetes on GCP Compute instances - then yes, it is possible to create multi-region cluster in single VPC.
