module: gcp_compute_backend_bucket
description:
- Backend buckets allow you to use Google Cloud Storage buckets with HTTP(S) load
balancing.
- An HTTP(S) load balancer can direct traffic to specified URLs to a backend bucket
rather than a backend service. It can send requests for static content to a Cloud
Storage bucket and requests for dynamic content a virtual machine instance.
short_description: Creates a GCP BackendBucket
version_added: 2.6
author: Google Inc. (@googlecloudplatform)
requirements:
- python >= 2.6
- requests >= 2.18.4
- google-auth >= 1.3.0
options:

- Whether the given object should exist in GCP
choices: ['present', 'absent']
default: 'present'

description:
- Cloud Storage bucket name.
required: true
description:
description:
- An optional textual description of the resource; provided by the client when the
resource is created.
required: false
enable_cdn:
description:
- If true, enable Cloud CDN for this BackendBucket.
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.
