module: rax_cdb
short_description: create / delete or resize a Rackspace Cloud Databases instance
description:
- creates / deletes or resize a Rackspace Cloud Databases instance
and optionally waits for it to be 'running'. The name option needs to be unique since
it's used to identify the instance.
version_added: "1.8"
options:
api_key:
description:
- Rackspace API key (overrides I(credentials))
aliases:
- password
credentials:
description:
- File to find the Rackspace credentials in (ignored if I(api_key) and
I(username) are provided)
default: null
aliases:
- creds_file
region:
description:
- Region to create an instance in
default: DFW
username:
description:
- Rackspace username (overrides I(credentials))
name:
description:
- Name of the databases server instance
default: null
flavor:
description:
- flavor to use for the instance 1 to 6 (i.e. 512MB to 16GB)
default: 1
volume:
description:
- Volume size of the database 1-150GB
default: 2
state:
description:
- Indicate desired state of the resource
choices: ['present', 'absent']
default: present
wait:
description:
- wait for the instance to be in state 'running' before returning
default: "no"
choices: [ "yes", "no" ]
wait_timeout:
description:
- how long before wait gives up, in seconds
default: 300
requirements: [ "pyrax" ]
author: Simon JAILLET
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, ...)
