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', 'deleted']
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, ...)
