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. If unspecified, the defaults are used.

Returned: success

accelerators

string

The number of accelerator cards exposed to an instance.

Returned: success

acceleratorType

string

The accelerator type resource name.

Returned: success

diskSizeGb

integer

Returned: success

diskType

string

Type of the disk attached to each node (e.g. ‘pd-standard’ or ‘pd-ssd’) If unspecified, the default disk type is ‘pd-standard’ .

Returned: success

imageType

string

The image type to use for this node. Note that for a given image type, the latest version of it will be used.

Returned: success

labels

dictionary

The map of Kubernetes labels (key/value pairs) to be applied to each node. These will added in addition to any default label(s) that Kubernetes may apply to the node. In case of conflict in label keys, the applied set may differ depending on the Kubernetes version – it’s best to assume the behavior is undefined and conflicts should be avoided. For more information, including usage and the valid values, see: http://kubernetes.io/v1.1/docs/user-guide/labels.html An object containing a list of “key”: value pairs.

Example: { “name”: “wrench”, “mass”: “1.3kg”, “count”: “3” }.

Returned: success

localSsdCount

integer

The number of local SSD disks to be attached to the node.

The limit for this value is dependant upon the maximum number of disks available on a machine per zone. See: https://cloud.google.com/compute/docs/disks/local-ssd#local_ssd_limits for more information.

Returned: success

machineType

string

The name of a Google Compute Engine machine type (e.g.

n1-standard-1). If unspecified, the default machine type is n1-standard-1.

Returned: success

metadata

dictionary

The metadata key/value pairs assigned to instances in the cluster.

Keys must conform to the regexp [a-zA-Z0-9-_]+ and be less than 128 bytes in length. These are reflected as part of a URL in the metadata server. Additionally, to avoid ambiguity, keys must not conflict with any other metadata keys for the project or be one of the four reserved keys: “instance-template”, “kube-env”, “startup-script”, and “user-data” Values are free-form strings, and only have meaning as interpreted by the image running in the instance. The only restriction placed on them is that each value’s size must be less than or equal to 32 KB.

The total size of all keys and values must be less than 512 KB.

An object containing a list of “key”: value pairs.

Example: { “name”: “wrench”, “mass”: “1.3kg”, “count”: “3” }.

Returned: success

minCpuPlatform

string

Minimum CPU platform to be used by this instance. The instance may be scheduled on the specified or newer CPU platform.

Returned: success

oauthScopes

list / elements=string

The set of Google API scopes to be made available on all of the node VMs under the “default” service account.

The following scopes are recommended, but not required, and by default are not included: https://www.googleapis.com/auth/compute is required for mounting persistent storage on your nodes.

https://www.googleapis.com/auth/devstorage.read_only is required for communicating with gcr.io (the Google Container Registry).

If unspecified, no scopes are added, unless Cloud Logging or Cloud Monitoring are enabled, in which case their required scopes will be added.

Returned: success

preemptible

boolean

Whether the nodes are created as preemptible VM instances. See: https://cloud.google.com/compute/docs/instances/preemptible for more information about preemptible VM instances.

Returned: success

serviceAccount

string

The Google Cloud Platform Service Account to be used by the node VMs. If no Service Account is specified, the “default” service account is used.

Returned: success

shieldedInstanceConfig

complex

Shielded Instance options.

Returned: success

enableIntegrityMonitoring

boolean

Defines whether the instance has integrity monitoring enabled.

Enables monitoring and attestation of the boot integrity of the instance.

The attestation is performed against the integrity policy baseline. This baseline is initially derived from the implicitly trusted boot image when the instance is created.

Returned: success

enableSecureBoot

boolean

Defines whether the instance has Secure Boot enabled.

Secure Boot helps ensure that the system only runs authentic software by verifying the digital signature of all boot components, and halting the boot process if signature verification fails.

Returned: success

tags

list / elements=string

The list of instance tags applied to all nodes. Tags are used to identify valid sources or targets for network firewalls and are specified by the client during cluster or node pool creation. Each tag within the list must comply with RFC1035.

Returned: success

taints

complex

List of kubernetes taints to be applied to each node.

For more information, including usage and the valid values, see: https://kubernetes.io/docs/concepts/configuration/taint-and-toleration/ .

Returned: success

effect

string

Effect for taint.

Returned: success

key

string

Key for taint.

Returned: success

value

string

Value for taint.

Returned: success

nodeIpv4CidrSize

integer

The size of the address space on each node for hosting containers.

This is provisioned from within the container_ipv4_cidr range.

Returned: success

enablePrivateEndpoint

boolean

Whether the master’s internal IP address is used as the cluster endpoint.

Returned: success

boolean

Whether nodes have internal IP addresses only. If enabled, all nodes are given only RFC 1918 private addresses and communicate with the master via private networking.

Returned: success

masterIpv4CidrBlock

string

The IP range in CIDR notation to use for the hosted master network. This range will be used for assigning internal IP addresses to the master or set of masters, as well as the ILB VIP. This range must not overlap with any other ranges in use within the cluster’s network.

Returned: success

privateEndpoint

string

The internal IP address of this cluster’s master endpoint.

Returned: success

publicEndpoint

string

The external IP address of this cluster’s master endpoint.

Returned: success

releaseChannel

complex

ReleaseChannel indicates which release channel a cluster is subscribed to.

Release channels are arranged in order of risk and frequency of updates.

Returned: success

channel

string

Which release channel the cluster is subscribed to.

Returned: success

resourceLabels

dictionary

The resource labels for the cluster to use to annotate any related Google Compute Engine resources.

Returned: success

servicesIpv4Cidr

string

The IP address range of the Kubernetes services in this cluster, in CIDR notation (e.g. 1.2.3.4/29). Service addresses are typically put in the last /16 from the container CIDR.
