- 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 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.
