google.cloud.gcp_compute_autoscaler_info module – Gather info for GCP Autoscaler

Note

This module is part of the google.cloud collection (version 1.4.1).

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. You need further requirements to be able to use this module, see Requirements for details.

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

Note

The google.cloud collection will be removed from Ansible 12 due to violations of the Ansible inclusion requirements. The collection has unresolved sanity test failures. See the discussion thread for more information.

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
access_token string	An OAuth2 access token if credential type is accesstoken.
auth_kind string / required	The type of credential used. Choices: `"application"` `"machineaccount"` `"serviceaccount"` `"accesstoken"`
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.
filters list / elements=string	A list of filter value pairs. Available filters are listed here https://cloud.google.com/sdk/gcloud/reference/topic/filters. Each additional filter in the list will act be added as an AND condition (filter1 and filter2) .
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.
zone string / required	URL of the zone where the instance group resides.

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_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 access_token using the GCP_ACCESS_TOKEN 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	Description
resources complex	List of resources Returned: always
autoscalingPolicy complex	The configuration parameters for the autoscaling algorithm. You can define one or more of the policies for an autoscaler: cpuUtilization, customMetricUtilizations, and loadBalancingUtilization. If none of these are specified, the default will be to autoscale based on cpuUtilization to 0.6 or 60%. Returned: success
coolDownPeriodSec integer	The number of seconds that the autoscaler should wait before it starts collecting information from a new instance. This prevents the autoscaler from collecting information when the instance is initializing, during which the collected usage would not be reliable. The default time autoscaler waits is 60 seconds. Virtual machine initialization times might vary because of numerous factors. We recommend that you test how long an instance may take to initialize. To do this, create an instance and time the startup process. Returned: success
cpuUtilization complex	Defines the CPU utilization policy that allows the autoscaler to scale based on the average CPU utilization of a managed instance group. Returned: success
predictiveMethod string	Indicates whether predictive autoscaling based on CPU metric is enabled. Valid values are: - NONE (default). No predictive method is used. The autoscaler scales the group to meet current demand based on real-time metrics. OPTIMIZE_AVAILABILITY. Predictive autoscaling improves availability by monitoring daily and weekly load patterns and scaling out ahead of anticipated demand. Returned: success
utilizationTarget string	The target CPU utilization that the autoscaler should maintain. Must be a float value in the range (0, 1]. If not specified, the default is 0.6. If the CPU level is below the target utilization, the autoscaler scales down the number of instances until it reaches the minimum number of instances you specified or until the average CPU of your instances reaches the target utilization. If the average CPU is above the target utilization, the autoscaler scales up until it reaches the maximum number of instances you specified or until the average utilization reaches the target utilization. Returned: success
customMetricUtilizations complex	Configuration parameters of autoscaling based on a custom metric. Returned: success
metric string	The identifier (type) of the Stackdriver Monitoring metric. The metric cannot have negative values. The metric must have a value type of INT64 or DOUBLE. Returned: success
utilizationTarget string	The target value of the metric that autoscaler should maintain. This must be a positive value. A utilization metric scales number of virtual machines handling requests to increase or decrease proportionally to the metric. For example, a good metric to use as a utilizationTarget is www.googleapis.com/compute/instance/network/received_bytes_count. The autoscaler will work to keep this value constant for each of the instances. Returned: success
utilizationTargetType string	Defines how target utilization value is expressed for a Stackdriver Monitoring metric. Returned: success
loadBalancingUtilization complex	Configuration parameters of autoscaling based on a load balancer. Returned: success
utilizationTarget string	Fraction of backend capacity utilization (set in HTTP(s) load balancing configuration) that autoscaler should maintain. Must be a positive float value. If not defined, the default is 0.8. Returned: success
maxNumReplicas integer	The maximum number of instances that the autoscaler can scale up to. This is required when creating or updating an autoscaler. The maximum number of replicas should not be lower than minimal number of replicas. Returned: success
minNumReplicas integer	The minimum number of replicas that the autoscaler can scale down to. This cannot be less than 0. If not provided, autoscaler will choose a default value depending on maximum number of instances allowed. Returned: success
mode string	Defines operating mode for this policy. Returned: success
scaleInControl complex	Defines scale in controls to reduce the risk of response latency and outages due to abrupt scale-in events . Returned: success
maxScaledInReplicas complex	A nested object resource. Returned: success
fixed integer	Specifies a fixed number of VM instances. This must be a positive integer. Returned: success
percent integer	Specifies a percentage of instances between 0 to 100%, inclusive. For example, specify 80 for 80%. Returned: success
timeWindowSec integer	How long back autoscaling should look when computing recommendations to include directives regarding slower scale down, as described above. Returned: success
creationTimestamp string	Creation timestamp in RFC3339 text format. Returned: success
description string	An optional description of this resource. Returned: success
id integer	Unique identifier for the resource. Returned: success
name string	Name of the resource. The name must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9][a-z0-9])?` which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash. Returned:* success
target dictionary	URL of the managed instance group that this autoscaler will scale. Returned: success
zone string	URL of the zone where the instance group resides. Returned: success
