# this is a bit of an advanced topic.

# generally Ansible likes to pass simple key=value arguments to modules. It occasionally comes up though
|
|
# that you might want to write a module that takes COMPLEX arguments, like lists and dictionaries.
|
|
#
|
|
# happen, at least right now, it should be a Python module, so it can leverage some common code in Ansible that
|
|
# makes this easy. If you write a non-Python module, you can still pass data across, but only hashes that
|
|
# do not contain lists or other hashes. If you write the Python module, you can do anything.
|
|
#
|
|
# note that if you were to use BOTH the key=value form and the 'args' form for passing data in, the key=value
|
|
# parameters take a higher priority, so you can use them for defaults, which can be useful.

- name: this is the basic way data passing works for any module
|
|
action: ping data='Hi Mom'
|
|
|
|
- name: of course this can also be written like so, which is shorter
|
|
ping: data='Hi Mom'
|
|
|
|
- name: but what if you have a complex module that needs complicated data?
|

action: ping

|

data:
|
|
moo: cow

- name: here is an example of how it works with defaults, notice the key=value format wins
|
