Fields
name

string

The name of this cluster. The name must be unique within this project and location (e.g. zone or region), and can be up to 40 characters with the following restrictions:

  • Lowercase letters, numbers, and hyphens only.
  • Must start with a letter.
  • Must end with a number or a letter.
description

string

An optional description of this cluster.
initialNodeCount
(deprecated)

integer

The number of nodes to create in this cluster. You must ensure that your Compute Engine resource quota 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 "nodePool" object, since this configuration (along with the "nodeConfig") will be used to create a "NodePool" object with an auto-generated name. Do not use this and a nodePool at the same time.

This field is deprecated, use nodePool.initial_node_count instead.
nodeConfig
(deprecated)

object (NodeConfig)

Parameters used in creating the cluster's nodes. For requests, this field should only be used in lieu of a "nodePool" object, since this configuration (along with the "initialNodeCount") will be used to create a "NodePool" object with an auto-generated name. Do not use this and a nodePool at the same time. For responses, this field will be populated with the node configuration of the first node pool. (For configuration of each node pool, see nodePool.config)

If unspecified, the defaults are used. This field is deprecated, use nodePool.config instead.
masterAuth

object (MasterAuth)

The authentication information for accessing the master endpoint. If unspecified, the defaults are used: For clusters before v1.12, if masterAuth is unspecified, username will be set to "admin", a random password will be generated, and a client certificate will be issued.
loggingService

string

The logging service the cluster should use to write logs. Currently available options:

  • logging.googleapis.com/kubernetes - The Cloud Logging service with a Kubernetes-native resource model

  • none - no logs will be exported from the cluster.

If left as an empty string,logging.googleapis.com/kubernetes will be used for GKE 1.14+ or logging.googleapis.com for earlier versions.
monitoringService

string

The monitoring service the cluster should use to write metrics. Currently available options:

  • "monitoring.googleapis.com/kubernetes" - The Cloud Monitoring service with a Kubernetes-native resource model
  • monitoring.googleapis.com - The legacy Cloud Monitoring service (no longer available as of GKE 1.15).
  • none - No metrics will be exported from the cluster.

If left as an empty string,monitoring.googleapis.com/kubernetes will be used for GKE 1.14+ or monitoring.googleapis.com for earlier versions.

Warning: changing cluster locations will update the NodePool.Locations of all node pools and will result in nodes being added and/or removed.
enableKubernetesAlpha

boolean

Kubernetes alpha features are enabled on this cluster. This includes alpha API groups (e.g. v1alpha1) and features that may not be production ready in the kubernetes version of the master and nodes. The cluster has no SLA for uptime and master/node upgrades are disabled. Alpha enabled clusters are automatically deleted thirty days after creation.
