but i am not sure how to do this can someone please guide me

Answer: 
You cannot do this using gcloud or the cloud console, but you can achieve what you are trying to do if you use the raw [GKE API](https://cloud.google.com/container-engine/reference/rest/v1/projects.zones.clusters/create). In the request body you would need to specify multiple [NodePool objects](https://cloud.google.com/container-engine/reference/rest/v1/projects.zones.clusters.nodePools#NodePool), putting in the name you'd like for each one. You can make programmatic calls using a [client library](https://developers.google.com/discovery/libraries) so that you don't have to craft raw HTTP requests by hand.
What you are trying to achieve is not possible without using the additional steps you are following. All the [clusters are created](https://cloudplatform.googleblog.com/2016/05/introducing-Google-Container-Engine-GKE-node-pools.html) using a default node pool named “default pool”
. Therefore, there is no option on the WUI or [flag on gcloud](https://cloud.google.com/sdk/gcloud/reference/container/clusters/create) that can be used for this. You might want to reply to Robert’s comment, your use case and feedback is important to improve Google’s products.
