module: rax_network
short_description: create / delete an isolated network in Rackspace Public Cloud
description:
     - creates / deletes a Rackspace Public Cloud isolated network.
version_added: "1.4"
options:
  state:
    description:
     - Indicate desired state of the resource
    choices: ['present', 'absent']
    default: present
  credentials:
    description:
     - File to find the Rackspace credentials in (ignored if C(api_key) and
       C(username) are provided)
    default: null
    aliases: ['creds_file']
  api_key:
    description:
     - Rackspace API key (overrides C(credentials))
  username:
    description:
     - Rackspace username (overrides C(credentials))
  label:
    description:
     - Label (name) to give the network
    default: null
  cidr:
    description:
     - cidr of the network being created
    default: null
  region:
    description:
     - Region to create the network in
    default: DFW
requirements: [ "pyrax" ]
author: Christopher H. Laco, Jesse Keating
notes:
  - The following environment variables can be used, C(RAX_USERNAME),
    C(RAX_API_KEY), C(RAX_CREDS), C(RAX_CREDENTIALS), C(RAX_REGION).
  - C(RAX_CREDENTIALS) and C(RAX_CREDS) points to a credentials file
    appropriate for pyrax
  - 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, ...)
