short_description: Add and Delete public ips on servers in CenturyLink Cloud.
|
||||
description:
|
||||
- An Ansible module to add or delete public ip addresses on an existing server or servers in CenturyLink Cloud.
|
||||
version_added: 1.0
|
||||
options:
|
||||
protocol:
|
||||
descirption:
|
||||
- The protocol that the public IP will listen for.
|
||||
default: TCP
|
||||
choices: ['TCP', 'UDP', 'ICMP']
|
||||
required: False
|
||||
ports:

- A list of servers to create public ips on.
|
||||
required: True
|
||||
state:
|
||||
description:
|
||||
- Determine wheteher to create or delete public IPs. If present module will not create a second public ip if one
|
||||
already exists.
|
||||
default: present
|
||||
choices: ['present', 'absent']
|
||||
required: False
|

- 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.

||||
