module: rax_cbs_attachments
short_description: Manipulate Rackspace Cloud Block Storage Volume Attachments
description:
- Manipulate Rackspace Cloud Block Storage Volume Attachments
version_added: 1.6
options:

credentials:
description:
- File to find the Rackspace credentials in (ignored if I(api_key) and
I(username) are provided)
default: null
aliases:
- creds_file
env:
description:
- Environment as configured in ~/.pyrax.cfg,
see U(https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#pyrax-configuration)
identity_type:
description:
- Authentication machanism to use, such as rackspace or keystone
default: rackspace
region:
description:
- Region to create an instance in
default: DFW
tenant_id:
description:
- The tenant ID used for authentication
tenant_name:
description:
- The tenant name used for authentication
username:
description:
- Rackspace username (overrides I(credentials))
verify_ssl:
description:
- Whether or not to require SSL validation of API endpoints
device:
description:
- The device path to attach the volume to, e.g. /dev/xvde
default: null
required: true
volume:
description:
- Name or id of the volume to attach/detach
default: null
required: true
server:
description:
- Name or id of the server to attach/detach
default: null
required: true
state:
description:
- Indicate desired state of the resource
choices:
- present
- absent
default: present
required: true
wait:
description:
- wait for the volume to be in 'in-use'/'available' state before returning
default: "no"
choices:
- "yes"
- "no"
wait_timeout:
description:
- how long before wait gives up, in seconds
default: 300
requirements:
- pyrax
author: Christopher H. Laco, 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, ...)
