notes:
|
|
||||||
- This module will return C(floating_ip) on success, which will contain the
|
|
||||||
public IP address associated with the instance.
|
|
||||||
- There may be a delay between the time the floating IP is assigned and when
|
|
||||||
the cloud instance is reachable via the new address. Use wait_for and pause
|
|
||||||
to delay further playbook execution until the instance is reachable, if
|
|
||||||
necessary.
