module: clc_aa_policy
short_description: Create or Delete Anti Affinity Policies at CenturyLink Cloud.
description:
- An Ansible module to Create or Delete Anti Affinity Policies at CenturyLink Cloud.
version_added: "2.0"
options:
name:
description:
- The name of the Anti Affinity Policy.
required: True
location:
description:
- Datacenter in which the policy lives/should live.
required: True
state:
description:
- Whether to create or delete the policy.
required: False
default: present
choices: ['present','absent']
wait:
description:
- Whether to wait for the tasks to finish before returning.
default: True
required: False
choices: [True, 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 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.
