Gather info for GCP Autoscaler

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.
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		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		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 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.

Examples ¶

- name: get info on an autoscaler
  gcp_compute_autoscaler_info:
    zone: us-central1-a
    filters:
    - name = test_object
    project: test_project
    auth_kind: serviceaccount
    service_account_file: "/tmp/auth.pem"

Return Values ¶

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

Key				Returned	Description
resources complex				always	List of resources
	autoscalingPolicy complex			success	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%.
		coolDownPeriodSec integer		success	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.
		cpuUtilization complex		success	Defines the CPU utilization policy that allows the autoscaler to scale based on the average CPU utilization of a managed instance group.
			utilizationTarget string	success	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.
		customMetricUtilizations complex		success	Defines the CPU utilization policy that allows the autoscaler to scale based on the average CPU utilization of a managed instance group.
			metric string	success	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.
			utilizationTarget string	success	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.
			utilizationTargetType string	success	Defines how target utilization value is expressed for a Stackdriver Monitoring metric. Either GAUGE, DELTA_PER_SECOND, or DELTA_PER_MINUTE.
		loadBalancingUtilization complex		success	Configuration parameters of autoscaling based on a load balancer.
			utilizationTarget string	success	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.
		maxNumReplicas integer		success	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.
		minNumReplicas integer		success	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.
	creationTimestamp string			success	Creation timestamp in RFC3339 text format.
	description string			success	An optional description of this resource.
	id integer			success	Unique identifier for the resource.
	name string			success	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.
	target dictionary			success	URL of the managed instance group that this autoscaler will scale.
	zone string			success	URL of the zone where the instance group resides.
