module: gcp_compute_instance_group
description:
- Represents an Instance Group resource. Instance groups are self-managed and can
contain identical or different instances. Instance groups do not use an instance
template. Unlike managed instance groups, you must create and add instances to an
instance group manually.
short_description: Creates a GCP InstanceGroup
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'
description:
description:
- An optional description of this resource. Provide this property when you create
the resource.
required: false
name:
description:
- The name of the instance group.
- The name must be 1-63 characters long, and comply with RFC1035.
required: false
named_ports:
description:
- Assigns a name to a port number.
- 'For example: {name: "http", port: 80}.'
- This allows the system to reference ports by the assigned name instead of a port
number. Named ports can also contain multiple ports.
- 'For example: [{name: "http", port: 80},{name: "http", port: 8080}] Named ports
apply to all instances in this instance group.'
required: false
suboptions:
name:
description:
- The name for this named port.
- The name must be 1-63 characters long, and comply with RFC1035.
required: false
port:
description:
- The port number, which can be a value between 1 and 65535.
required: false
network:
description:
- A reference to Network resource.
required: false
region:
description:
- A reference to Region resource.
required: false
subnetwork:
description:
- A reference to Subnetwork resource.
required: false
zone:
description:
- A reference to Zone resource.
