initial
Deprecated
The number of nodes to create in this cluster. You must ensure that your Compute Engine [resource quota](https://cloud.google.com/compute/quotas) is sufficient for this number of instances. You must also have available firewall and routes quota. For requests, this field should only be used in lieu of a "node_pool" object, since this configuration (along with the "node_config") will be used to create a "NodePool" object with an auto-generated name. Do not use this and a node_pool at the same time. This field is deprecated, use node_pool.initial_node_count instead.
