module: gcp_compute_target_pool
description:
- Represents a TargetPool resource, used for Load Balancing.
short_description: Creates a GCP TargetPool
version_added: 2.6
author: Google Inc. (@googlecloudplatform)
requirements:
- python >= 2.6
- requests >= 2.18.4
- google-auth >= 1.3.0
options:
state:
description:
- Whether the given object should exist in GCP
choices: ['present', 'absent']
default: 'present'
backup_pool:
description:
- A reference to TargetPool resource.
required: false
description:
description:
- An optional description of this resource.
required: false
failover_ratio:
description:
- 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.
required: false
health_check:
description:
- A reference to HttpHealthCheck resource.
required: false
instances:
description:
- A list of virtual machine instances serving this pool.
- They must live in zones contained in the same region as this pool.
required: false
name:
description:
- 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.
required: true
session_affinity:
description:
- '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."
required: false
choices: ['NONE', 'CLIENT_IP', 'CLIENT_IP_PROTO']
region:
description:
- A reference to Region resource.
required: true
