NodeConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)The configuration information for the Kubernetes Engine nodes running the Apache Airflow software.
Attributes
| Name | Description |
location |
str
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.
This field is supported for Cloud Composer environments in
versions composer-1.\ *.*-airflow-*.*.*.
|
machine_type |
str
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".
This field is supported for Cloud Composer environments in
versions composer-1.\ *.*-airflow-*.*.*.
|
network |
str
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.
|
subnetwork |
str
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.
|
disk_size_gb |
int
Optional. The disk size in GB used for node VMs. Minimum size is 30GB. If unspecified, defaults to 100GB. Cannot be updated. This field is supported for Cloud Composer environments in versions composer-1.\ *.*-airflow-*.*.*. |
oauth_scopes |
MutableSequence[str]
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.
This field is supported for Cloud Composer environments in
versions composer-1.\ *.*-airflow-*.*.*.
|
service_account |
str
Optional. The Google Cloud Platform Service Account to be used by the workloads. If a service account is not specified, the "default" Compute Engine service account is used. Cannot be updated. |
tags |
MutableSequence[str]
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.
This field is supported for Cloud Composer environments in
versions composer-1.\ *.*-airflow-*.*.*.
|
ip_allocation_policy |
google.cloud.orchestration.airflow.service_v1beta1.types.IPAllocationPolicy
Optional. The IPAllocationPolicy fields for the GKE cluster. |
max_pods_per_node |
int
Optional. The maximum number of pods per node in the Cloud Composer GKE cluster. The value must be between 8 and 110 and it can be set only if the environment is VPC-native. The default value is 32. Values of this field will be propagated both to the default-pool node pool of the newly created
GKE cluster, and to the default "Maximum Pods per Node"
value which is used for newly created node pools if their
value is not explicitly set during node pool creation. For
more information, see [Optimizing IP address allocation]
(https://cloud.google.com/kubernetes-engine/docs/how-to/flexible-pod-cidr).
Cannot be updated.
This field is supported for Cloud Composer environments in
versions composer-1.\ *.*-airflow-*.*.*.
|
enable_ip_masq_agent |
bool
Optional. Deploys 'ip-masq-agent' daemon set in the GKE cluster and defines nonMasqueradeCIDRs equals to pod IP range so IP masquerading is used for all destination addresses, except between pods traffic. See: https://cloud.google.com/kubernetes-engine/docs/how-to/ip-masquerade-agent |
