|

description:
|
||||
- Manage OVH (French European hosting provider) IP Failover Address. For now, this module can only be used to move
|
||||
an ip failover (or failover block) between services
|
||||
version_added: "2.8"
|
||||
author: "Pascal HERAUD (@pascalheraud)"
|
||||
notes:
|
||||
- Uses the python OVH Api U(https://github.com/ovh/python-ovh).
|
||||
You have to create an application (a key and secret) with a consummer
|
||||
key as described into U(https://eu.api.ovh.com/g934.first_step_with_api)
|
||||
requirements:
|
||||
- ovh >= 0.4.8
|
||||
options:
|
||||
name:
|
||||
required: true
|
||||
description:

- The IP address to manage (can be a single IP like 1.1.1.1
|
||||
or a block like 1.1.1.1/28 )

wait_completion:

required: false
|

default: true
|
||||
type: bool
|
||||
description:
|
||||
- If true, the module will wait for the IP address to be moved.
|
||||
If false, exit without waiting. The taskId will be returned
|
||||
in module output
|
||||
wait_task_completion:
|
||||
required: false
|
||||
default: 0
|
||||
description:
|
||||
- If not 0, the module will wait for this task id to be
|
||||
completed. Use wait_task_completion if you want to wait for
|
||||
completion of a previously executed task with
|
||||
wait_completion=false. You can execute this module repeatedly on
|
||||
a list of failover IPs using wait_completion=false (see examples)
