Use GKE beta features with GCP Deployment Manager - google-cloud-platform

Question

I'm trying to create GKE REGION cluster (beta feature) with GCP deployment manager.
But I got error. Is there any way to use GKE beta features (include region cluster) with deployment manager?
ERROR: (gcloud.beta.deployment-manager.deployments.create) Error in

In the error message, link of gcp help.
https://cloud.google.com/kubernetes-engine/docs/reference/api-organization#beta
Configured as described there but error still appears.
My deployment manager yaml file looks like,
resources:
- name: source-cluster
type: container.v1.cluster
properties:
zone: us-central1
cluster:
name: source
initialNodeCount: 3
Yet, zonal cluster is completely work. So I think it's related to usage of container v1beta api in deployment-manager commands.
resources:
- name: source-cluster
type: container.v1.cluster
properties:
zone: us-central1-b
cluster:
name: source
initialNodeCount: 3
Thanks.

The error message you are receiving appears to be related to the fact that you are attempting to use a beta feature but you are specifying a Deployment Manager resource as using API v1 (i.e. container.v1.cluster). This means there's inconstancy between the beta resource you are trying to create and the specified resource.
I've had a look into this and discovered that the ability to add regional clusters via Deployment Manager is a very recent addition to Google Cloud Platform as detailed in this public feature request which has only recently been implemented.
It seems you would need to specify the API type as 'gcp-types/container-v1beta1:projects.locations.clusters' for this to work, and rather than using the 'zone' or 'region' key in the YAML, you would instead use a parent property that includes locations.
So your YAML would look something like this (replace PROJECT_ID with your own).
resources:
- type: gcp-types/container-v1beta1:projects.locations.clusters
name: source-cluster
properties:
parent: projects/PROJECT_ID/locations/us-central1
cluster:
name: source
initialNodeCount: 3
