Parameters

Parameter Choices/Defaults Comments
auth_kind
string / required
    Choices:
  • application
  • machineaccount
  • serviceaccount
The type of credential used.
autoscaling_policy
dictionary
If you use sole-tenant nodes for your workloads, you can use the node group autoscaler to automatically manage the sizes of your node groups.
max_nodes
integer / required
Maximum size of the node group. Set to a value less than or equal to 100 and greater than or equal to min-nodes.
min_nodes
integer
Minimum size of the node group. Must be less than or equal to max-nodes. The default value is 0.
mode
string / required
The autoscaling mode. Set to one of the following: - OFF: Disables the autoscaler.
- ON: Enables scaling in and scaling out.
- ONLY_SCALE_OUT: Enables only scaling out.
You must use this mode if your node groups are configured to restart their hosted VMs on minimal servers.
Some valid choices include: "OFF", "ON", "ONLY_SCALE_OUT"
description
string
An optional textual description of the resource.
env_type
string
Specifies which Ansible environment you're running this module within.
This should not be set unless you know what you're doing.

Specifies how to handle instances when a node in the group undergoes maintenance. Set to one of: DEFAULT, RESTART_IN_PLACE, or MIGRATE_WITHIN_NODE_GROUP. The default value is DEFAULT.
name
string
Name of the resource.
node_template
dictionary / required
The URL of the node template to which this node group belongs.
This field represents a link to a NodeTemplate resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'selfLink' and value of your resource's selfLink Alternatively, you can add `register: name-of-resource` to a gcp_compute_node_template task and then set this node_template field to "{{ name-of-resource }}"
project
string
The Google Cloud Platform project to use.
scopes
list / elements=string
Array of scopes to be used
service_account_contents
jsonarg
The contents of a Service Account JSON file, either in a dictionary or as a JSON string that represents it.
service_account_email
string
An optional service account email address if machineaccount is selected and the user does not wish to use the default email.
service_account_file
path
The path of a Service Account JSON file if serviceaccount is selected as type.
size
integer / required
The total number of nodes in the node group.
state
string
    Choices:
  • present ←
  • absent
Whether the given object should exist in GCP
zone
string / required
Zone where this node group is located .

  • Sole-Tenant Nodes: https://cloud.google.com/compute/docs/nodes/

  • for authentication, you can set service_account_file using the gcp_service_account_file env variable.

  • for authentication, you can set service_account_contents using the GCP_SERVICE_ACCOUNT_CONTENTS env variable.

  • For authentication, you can set service_account_email using the GCP_SERVICE_ACCOUNT_EMAIL env variable.

  • For authentication, you can set auth_kind using the GCP_AUTH_KIND env variable.

  • For authentication, you can set scopes using the GCP_SCOPES env variable.

  • Environment variables values will only be used if the playbook values are not set.

  • The service_account_email and service_account_file options are mutually exclusive.
