If present module will not create a second public ip if one already exists. default: present choices: ['present', 'absent'] required: False wait: description: - Whether to wait for the tasks to finish before returning. choices: [ True, False ] default: True required: False requirements: - python = 2.7 - requests >= 2.5.0 - clc-sdk 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 passwod 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.
