module: rax_facts
short_description: Gather facts for Rackspace Cloud Servers
description:
- Gather facts for Rackspace Cloud Servers.
version_added: "1.4"
options:
address:
description:
- Server IP address to retrieve facts for, will match any IP assigned to
the server
api_key:
description:
- Rackspace API key (overrides C(credentials))
credentials:
description:
- File to find the Rackspace credentials in (ignored if C(api_key) and
C(username) are provided)
default: null
aliases: ['creds_file']
id:
description:
- Server ID to retrieve facts for
name:
description:
- Server name to retrieve facts for
default: null
region:
description:
- Region to create the load balancer in
default: DFW
username:
description:
- Rackspace username (overrides C(credentials))
requirements: [ "pyrax" ]
author: Matt Martz
notes:
- The following environment variables can be used, C(RAX_USERNAME),
C(RAX_API_KEY), C(RAX_CREDS_FILE), C(RAX_CREDENTIALS), C(RAX_REGION).
- C(RAX_CREDENTIALS) and C(RAX_CREDS_FILE) points to a credentials file
appropriate for pyrax. See U(https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#authenticating)
- C(RAX_USERNAME) and C(RAX_API_KEY) obviate the use of a credentials file
- C(RAX_REGION) defines a Rackspace Public Cloud region (DFW, ORD, LON, ...)
