# Example playbook to demonstrate the group_by action plugin.
|
|
#
|
|
# as we know, the setup module will automatically run in each play, and sets up various
|
|
# facts. We can then create temporary (in memory only) groups based on those facts, which
|
|
# are useful ways of selecting similar sets of hosts.
|
|
#
|
|
# Additionally, we can use the 'register' keyword in Ansible to set similar variables
|
|
# and use those for grouping. This is not shown in this example.
|

# the following host group does not exist in inventory and was created by the group_by
|
|
# module.
