gcp_compute_instance_group – Creates a GCP InstanceGroup

New in version 2.6.

Synopsis

  • Represents an Instance Group resource. Instance groups are self-managed and can contain identical or different instances. Instance groups do not use an instance template. Unlike managed instance groups, you must create and add instances to an instance group manually.

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 Choices/Defaults Comments
auth_kind
string / required
    Choices:
  • application
  • machineaccount
  • serviceaccount
The type of credential used.
description
string
An optional description of this resource. Provide this property when you create 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.
instances
list
added in 2.8
The list of instances associated with this InstanceGroup.
All instances must be created before being added to an InstanceGroup.
All instances not in this list will be removed from the InstanceGroup and will not be deleted.
Only the full identifier of the instance will be returned.
name
string
The name of the instance group.
The name must be 1-63 characters long, and comply with RFC1035.
named_ports
list
Assigns a name to a port number.
For example: {name: "http", port: 80}.
This allows the system to reference ports by the assigned name instead of a port number. Named ports can also contain multiple ports.
For example: [{name: "http", port: 80},{name: "http", port: 8080}] Named ports apply to all instances in this instance group.
name
string
The name for this named port.
The name must be 1-63 characters long, and comply with RFC1035.
port
integer
The port number, which can be a value between 1 and 65535.
network
dictionary
The network to which all instances in the instance group belong.
This field represents a link to a Network 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_network task and then set this network field to "{{ name-of-resource }}"
project
string
The Google Cloud Platform project to use.
region
string
The region where the instance group is located (for regional resources).
scopes
list
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.
state
string
    Choices:
  • present ←
  • absent
Whether the given object should exist in GCP
subnetwork
dictionary
The subnetwork to which all instances in the instance group belong.
This field represents a link to a Subnetwork 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_subnetwork task and then set this subnetwork field to "{{ name-of-resource }}"
zone
string / required
A reference to the zone where the instance group resides.

Notes

Note

  • for authentication, you can set service_account_file using the c(gcp_service_account_file) env variable.
  • for authentication, you can set service_account_contents using the c(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.
