 * tags: Defines the tags that will be attached to new nodes in the cluster. This is to grant access through ports via the firewall created in the next step.
 * scopes: Defines the Oauth scopes required by the nodes.
 * num-nodes: The number of nodes to be created in each of the cluster's zones. Default: 4. Depending on the needs of your game, this parameter should be adjusted.
