  • google-auth >= 1.3.0

Parameters

Parameter Choices/Defaults Comments
auth_kind
string / required
    Choices:
  • application
  • machineaccount
  • serviceaccount
The type of credential used.
backup_pool
-
This field is applicable only when the containing target pool is serving a forwarding rule as the primary pool, and its failoverRatio field is properly set to a value between [0, 1].
backupPool and failoverRatio together define the fallback behavior of the primary target pool: if the ratio of the healthy instances in the primary pool is at or below failoverRatio, traffic arriving at the load-balanced IP will be directed to the backup pool.
In case where failoverRatio and backupPool are not set, or all the instances in the backup pool are unhealthy, the traffic will be directed back to the primary pool in the "force" mode, where traffic will be spread to the healthy instances with the best effort, or to all instances when no instance is healthy.
This field represents a link to a TargetPool 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_target_pool task and then set this backup_pool field to "{{ name-of-resource }}"
description
-
An optional description of this resource.
failover_ratio
-
This field is applicable only when the containing target pool is serving a forwarding rule as the primary pool (i.e., not as a backup pool to some other target pool). The value of the field must be in [0, 1].
If set, backupPool must also be set. They together define the fallback behavior of the primary target pool: if the ratio of the healthy instances in the primary pool is at or below this number, traffic arriving at the load-balanced IP will be directed to the backup pool.
In case where failoverRatio is not set or all the instances in the backup pool are unhealthy, the traffic will be directed back to the primary pool in the "force" mode, where traffic will be spread to the healthy instances with the best effort, or to all instances when no instance is healthy.
health_check
-
A reference to a HttpHealthCheck resource.
A member instance in this pool is considered healthy if and only if the health checks pass. If not specified it means all member instances will be considered healthy at all times.
This field represents a link to a HttpHealthCheck 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_http_health_check task and then set this health_check field to "{{ name-of-resource }}"
instances
-
A list of virtual machine instances serving this pool.
They must live in zones contained in the same region as this pool.
name
- / required
Name of the resource. Provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, 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.
project
string
The Google Cloud Platform project to use.
region
- / required
The region where the target pool resides.
scopes
list
Array of scopes to be used.
service_account_contents
string
A string representing the contents of a Service Account JSON file.
This should not be passed in as a dictionary, but a string that has the exact contents of a service account json file (valid JSON)
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.
session_affinity
-
    Choices:
  • NONE
  • CLIENT_IP
  • CLIENT_IP_PROTO
Session affinity option. Must be one of these values: - NONE: Connections from the same client IP may go to any instance in the pool.
- CLIENT_IP: Connections from the same client IP will go to the same instance in the pool while that instance remains healthy.
- CLIENT_IP_PROTO: Connections from the same client IP with the same IP protocol will go to the same instance in the pool while that instance remains healthy.
state
-
    Choices:
  • present ←
  • absent
Whether the given object should exist in GCP

Notes

Note

  • API Reference: https://cloud.google.com/compute/docs/reference/rest/v1/targetPools
  • Official Documentation: https://cloud.google.com/compute/docs/load-balancing/network/target-pools
  • 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 service_account_contents using the GCP_SERVICE_ACCOUNT_CONTENTS 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
backupPool
dictionary
success

backupPool and failoverRatio together define the fallback behavior of the primary target pool: if the ratio of the healthy instances in the primary pool is at or below failoverRatio, traffic arriving at the load-balanced IP will be directed to the backup pool.
In case where failoverRatio and backupPool are not set, or all the instances in the backup pool are unhealthy, the traffic will be directed back to the primary pool in the "force" mode, where traffic will be spread to the healthy instances with the best effort, or to all instances when no instance is healthy.

description
string
success
An optional description of this resource.

string
success
This field is applicable only when the containing target pool is serving a forwarding rule as the primary pool (i.e., not as a backup pool to some other target pool). The value of the field must be in [0, 1].
If set, backupPool must also be set. They together define the fallback behavior of the primary target pool: if the ratio of the healthy instances in the primary pool is at or below this number, traffic arriving at the load-balanced IP will be directed to the backup pool.
In case where failoverRatio is not set or all the instances in the backup pool are unhealthy, the traffic will be directed back to the primary pool in the "force" mode, where traffic will be spread to the healthy instances with the best effort, or to all instances when no instance is healthy.
