google.cloud.gcp_compute_region_instance_group_manager – Creates a GCP RegionInstanceGroupManager

Note

This plugin 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_region_instance_group_manager.

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

This field represents a link to a InstanceTemplate 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_instance_template task and then set this instance_template field to "{{ name-of-resource }}"

named_ports
list / elements=dictionary
Named ports configured for the Instance Groups complementary to this Instance Group Manager.
name
string
The name for this named port. The name must be 1-63 characters long, and comply with RFC1035.
port

string / required
The region the managed instance group resides.
scopes
list / elements=string

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

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
target_pools
list / elements=dictionary
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
The target number of running instances for this managed instance group. Deleting or abandoning instances reduces this number. Resizing the group changes this number.

Return Values

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

Key Returned Description
autoHealingPolicies
complex
success
The autohealing policy for this managed instance group .

healthCheck
string
success
The URL for the health check that signals autohealing.

initialDelaySec
integer
success
The number of seconds that the managed instance group waits before it applies autohealing policies to new instances or recently recreated instances .

baseInstanceName
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.

creationTimestamp
string
success
The creation timestamp for this managed instance group in RFC3339 text format.

currentActions
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.

creatingWithoutRetries
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.

instanceGroup
dictionary
success
The instance group being managed.

instanceTemplate
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.

namedPorts
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 the managed instance group resides.

targetPools
list / elements=string
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.
