NodeConfig

Parameters that describe the nodes in a cluster.

GKE Autopilot clusters do not recognize parameters in NodeConfig. Use AutoprovisioningNodePoolDefaults instead.

Fields
machineType

string

The name of a Google Compute Engine machine type

If unspecified, the default machine type is e2-medium.
diskSizeGb

integer

Size of the disk attached to each node, specified in GB. The smallest allowed disk size is 10GB.

If unspecified, the default disk size is 100GB.
oauthScopes[]

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 Artifact Registry).

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

string

The Google Cloud Platform Service Account to be used by the node VMs. Specify the email address of the Service Account; otherwise, if no Service Account is specified, the "default" service account is used.
metadata

map (key: string, value: string)

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 reserved keys:

  • "cluster-location"
  • "cluster-name"
  • "cluster-uid"
  • "configure-sh"
  • "containerd-configure-sh"
  • "enable-os-login"
  • "gci-ensure-gke-docker"
  • "gci-metrics-enabled"
  • "gci-update-strategy"
  • "instance-template"
  • "kube-env"
  • "startup-script"
  • "user-data"
  • "disable-address-manager"
  • "windows-startup-script-ps1"
  • "common-psm1"
  • "k8s-node-setup-psm1"
  • "install-ssh-psm1"
  • "user-profile-psm1"

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.
