Deploy node-pool in different subnetwork in same yaml file - google-cloud-platform

Question

I am creating a yaml config to deploy a gke cluster with multi-node-pool. I like to be able to create a new cluster and put each node-pool in a different subnetwork. Can this be done.
I have tried putting the subnetwork in different part of the properties under the second node-pool but it errors out. Below is the following error.
message: '{"ResourceType":"gcp-types/container-v1:projects.locations.clusters.nodePools","ResourceErrorCode":"400","ResourceErrorMessage":{"code":400,"message":"Invalid
JSON payload received. Unknown name \"subnetwork\": Cannot find field.","status":"INVALID_ARGUMENT","details":[{"#type":"type.googleapis.com/google.rpc.BadRequest","fieldViolations":[{"description":"Invalid

The current code for the both node-pools. first node is creates but second one error out.
resources:
- name: myclus
type: gcp-types/container-v1:projects.locations.clusters

parent: projects/[PROJECT_ID]/locations/[ZONE/REGION]
cluster:

subnetwork: dev-web ### leave this field blank if using the default network
initialClusterVersion: "1.13"

I like the expected out come to have 2 node-pools in 2 different subnetworks.

Answer 1

I found out that this is actually not a limitation of Deployment Manager but a limitation of GKE.
We can’t assign a different subnet to different node pools, the network and subnets are defined at the cluster level. There is no “Subnetwork” field in the node pool API.
Here is a link you can refer to for more information.
