The configuration information for the Kubernetes Engine nodes running the Apache Airflow software.

Attributes

• diskSizeGb (type: integer(), default: nil) - Optional. The disk size in GB used for node VMs. Minimum size is 20GB. If unspecified, defaults to 100GB. Cannot be updated.

• ipAllocationPolicy (type: GoogleApi.Composer.V1beta1.Model.IPAllocationPolicy.t, default: nil) - Optional. The IPAllocationPolicy fields for the GKE cluster.

• location (type: String.t, default: nil) - Optional. The Compute Engine zone in which to deploy the VMs used to run the Apache Airflow software, specified as a relative resource name. For example: "projects/{projectId}/zones/{zoneId}".

  This location must belong to the enclosing environment's project and location. If both this field and nodeConfig.machineType are specified, nodeConfig.machineType must belong to this location; if both are unspecified, the service will pick a zone in the Compute Engine region corresponding to the Cloud Composer location, and propagate that choice to both fields. If only one field (location or nodeConfig.machineType) is specified, the location information from the specified field will be propagated to the unspecified field.

• machineType (type: String.t, default: nil) - Optional. The Compute Engine machine type used for cluster instances, specified as a relative resource name. For example: "projects/{projectId}/zones/{zoneId}/machineTypes/{machineTypeId}".

  The machineType must belong to the enclosing environment's project and location. If both this field and nodeConfig.location are specified, this machineType must belong to the nodeConfig.location; if both are unspecified, the service will pick a zone in the Compute Engine region corresponding to the Cloud Composer location, and propagate that choice to both fields. If exactly one of this field and nodeConfig.location is specified, the location information from the specified field will be propagated to the unspecified field.

  The machineTypeId must not be a shared-core machine type.

  If this field is unspecified, the machineTypeId defaults to "n1-standard-1".

• network (type: String.t, default: nil) - Optional. The Compute Engine network to be used for machine communications, specified as a relative resource name. For example: "projects/{projectId}/global/networks/{networkId}".

  If unspecified, the default network in the environment's project is used. If a Custom Subnet Network is provided, nodeConfig.subnetwork must also be provided. For Shared VPC subnetwork requirements, see nodeConfig.subnetwork.

• oauthScopes (type: list(String.t), default: nil) - Optional. The set of Google API scopes to be made available on all node VMs. If oauth_scopes is empty, defaults to ["https://www.googleapis.com/auth/cloud-platform"]. Cannot be updated.

• serviceAccount (type: String.t, default: nil) - Optional. The Google Cloud Platform Service Account to be used by the node VMs. If a service account is not specified, the "default" Compute Engine service account is used. Cannot be updated.

• subnetwork (type: String.t, default: nil) - Optional. The Compute Engine subnetwork to be used for machine communications, specified as a relative resource name. For example: "projects/{projectId}/regions/{regionId}/subnetworks/{subnetworkId}"

  If a subnetwork is provided, nodeConfig.network must also be provided, and the subnetwork must belong to the enclosing environment's project and location.

• tags (type: list(String.t), default: nil) - Optional. The list of instance tags applied to all node VMs. Tags are used to identify valid sources or targets for network firewalls. Each tag within the list must comply with RFC1035. Cannot be updated.
