description:
- Create or delete Server Groups at Centurylink Centurylink Cloud
version_added: "2.0"
options:
name:
description:
- The name of the Server Group
required: True
description:
description:
- A description of the Server Group
required: False
parent:
description:
- The parent group of the server group. If parent is not provided, it creates the group at top level.
required: False
location:
description:
- Datacenter to create the group in. If location is not provided, the group gets created in the default datacenter
associated with the account
required: False
state:
description:
- Whether to create or delete the group
default: present
choices: ['present', 'absent']
wait:
description:
- Whether to wait for the tasks to finish before returning.
type: bool
default: True
required: False
requirements:
- python = 2.7
- requests >= 2.5.0
- clc-sdk
author: "CLC Runner (@clc-runner)"
notes:
- To use this module, it is required to set the below environment variables which enables access to the
Centurylink Cloud
- CLC_V2_API_USERNAME, the account login id for the centurylink cloud
- CLC_V2_API_PASSWORD, the account password for the centurylink cloud
- Alternatively, the module accepts the API token and account alias. The API token can be generated using the
CLC account login and password via the HTTP api call @ https://api.ctl.io/v2/authentication/login
- CLC_V2_API_TOKEN, the API token generated from https://api.ctl.io/v2/authentication/login
- CLC_ACCT_ALIAS, the account alias associated with the centurylink cloud
- Users can set CLC_V2_API_URL to specify an endpoint for pointing to a different CLC environment.
