module: ovh_ip_failover
short_description: Manage OVH IP failover address
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 )
service:
required: true
description:
- The name of the OVH service this IP address should be routed
endpoint:
required: true
description:
- The endpoint to use ( for instance ovh-eu)
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)
application_key:
required: true
description:
- The applicationKey to use
application_secret:
required: true
description:
- The application secret to use
consumer_key:
required: true
description:
- The consumer key to use
timeout:
required: false
default: 120
description:
- The timeout in seconds used to wait for a task to be
completed. Default is 120 seconds.
