module: rax_cdb_user
2014-08-08 20:32:55 +02:00
short_description: create / delete a Rackspace Cloud Database
description:
- create / delete a database in the Cloud Databases.
2014-08-08 20:32:55 +02:00
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))
cdb_id:
description:
- The databases server UUID
default: null
db_username:
description:
- Name of the database user
default: null
db_password:
description:
- Database user password
default: null
databases:
description:
- Name of the databases that the user can access
default: []
host:
description:
- Specifies the host from which a user is allowed to connect to
the database. Possible values are a string containing an IPv4 address
or "%" to allow connecting from any host
default: '%'
state:
description:
- Indicate desired state of the resource
choices: ['present', 'absent']
default: present
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, ...)
