google.cloud.gcp_compute_node_group module – Creates a GCP NodeGroup

Note

This module is part of the google.cloud collection (version 1.0.2).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install google.cloud.

To use it in a playbook, specify: google.cloud.gcp_compute_node_group.

Synopsis

  • Represents a NodeGroup resource to manage a group of sole-tenant nodes.

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 2.6

  • requests >= 2.18.4

  • google-auth >= 1.3.0

Parameters

Parameter

Comments

auth_kind

string / required

The type of credential used.

Choices:

  • application

  • machineaccount

  • serviceaccount

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.

This only alters the User Agent string for any API requests.

maintenance_policy

string

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.

Default: “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

Whether the given object should exist in GCP

Choices:

  • present ← (default)

  • absent

zone

string / required

Zone where this node group is located .

  • API Reference: https://cloud.google.com/compute/docs/reference/rest/v1/nodeGroups

  • 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.
