Hi@MD,
A cluster consists of at least one cluster master machine and multiple worker machines called nodes. Nodes are Compute Engine virtual machine (VM) instances that run the Kubernetes processes necessary to make them part of the cluster. You deploy applications to clusters, and the applications run on the nodes.
The following command creates a one-node cluster. Replace cluster-name with the name of your cluster.
$ gcloud container clusters create cluster-name --num-nodes=1
