gcp_compute_instance_group_manager – Creates a GCP InstanceGroupManager

New in version 2.6.

Synopsis

  • Creates a managed instance group using the information that you specify in the request. After the group is created, it schedules an action to create instances in the group using the specified instance template. This operation is marked as DONE when the group is created even if the instances in the group have not yet been created. You must separately verify the status of the individual instances.
  • A managed instance group can have up to 1000 VM instances per group.

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

Notes

Note

  • For authentication, you can set service_account_file using the GCP_SERVICE_ACCOUNT_FILE 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.

Return Values

Common return values are documented here, the following are the fields unique to this module:

Key Returned Description
base_instance_name
string
 success
The base instance name to use for instances in this group. The value must be 1-58 characters long. Instances are named by appending a hyphen and a random four-character string to the base instance name.
The base instance name must comply with RFC1035.
creation_timestamp
string
 success
The creation timestamp for this managed instance group in RFC3339 text format.
current_actions
complex
 success
The list of instance actions and the number of instances in this managed instance group that are scheduled for each of those actions.
  abandoning
integer
 success
The total number of instances in the managed instance group that are scheduled to be abandoned. Abandoning an instance removes it from the managed instance group without deleting it.
  creating
integer
 success
The number of instances in the managed instance group that are scheduled to be created or are currently being created. If the group fails to create any of these instances, it tries again until it creates the instance successfully.
If you have disabled creation retries, this field will not be populated; instead, the creatingWithoutRetries field will be populated.
  creating_without_retries
integer
 success
The number of instances that the managed instance group will attempt to create. The group attempts to create each instance only once. If the group fails to create any of these instances, it decreases the group's targetSize value accordingly.
  deleting
integer
 success
The number of instances in the managed instance group that are scheduled to be deleted or are currently being deleted.
  none
integer
 success
The number of instances in the managed instance group that are running and have no scheduled actions.
  recreating
integer
 success
The number of instances in the managed instance group that are scheduled to be recreated or are currently being being recreated.
Recreating an instance deletes the existing root persistent disk and creates a new disk from the image that is defined in the instance template.
  refreshing
integer
 success
The number of instances in the managed instance group that are being reconfigured with properties that do not require a restart or a recreate action. For example, setting or removing target pools for the instance.
  restarting
integer
 success
The number of instances in the managed instance group that are scheduled to be restarted or are currently being restarted.
description
string
 success
An optional description of this resource. Provide this property when you create the resource.
id
integer
 success
A unique identifier for this resource.
instance_group
dictionary
 success
The instance group being managed.
instance_template
dictionary
 success
The instance template that is specified for this managed instance group. The group uses this template to create all new instances in the managed instance group.
name
string
 success
The name of the managed instance group. The name must be 1-63 characters long, and comply with RFC1035.
named_ports
complex
 success
Named ports configured for the Instance Groups complementary to this Instance Group Manager.
  name
string
 success
The name for this named port. The name must be 1-63 characters long, and comply with RFC1035.
  port
integer
 success
The port number, which can be a value between 1 and 65535.
region
string
 success
The region this managed instance group resides (for regional resources).
target_pools
list
 success
TargetPool resources to which instances in the instanceGroup field are added. The target pools automatically apply to all of the instances in the managed instance group.
target_size
integer
 success
The target number of running instances for this managed instance group. Deleting or abandoning instances reduces this number. Resizing the group changes this number.
zone
string
 success
The zone the managed instance group resides.
