In order to simplify the workflow with the GCE modules, it's now possible to add the parameters and project name as arguments to the various GCE modules. The inventory plugin also returns the IP of the host in `ansible_ssh_host` so that you don't have to specify IPs into the inventory file. Some update to the documentation are also added. Closes #5583.

module: gce_pd
|
|
version_added: "1.4"
|
|
short_description: utilize GCE persistent disk resources
|
|
description:
|
|
- This module can create and destroy unformatted GCE persistent disks
|
|
U(https://developers.google.com/compute/docs/disks#persistentdisks).
|
|
It also supports attaching and detaching disks from running instances
|
|
but does not support creating boot disks from images or snapshots. The
|
|
'gce' module supports creating instances with boot disks.
|
|
Full install/configuration instructions for the gce* modules can
|
|
be found in the comments of ansible/test/gce_tests.py.
