Having a devil of a time writing my first plugin. The idea is simple, but
the examples I find are not helping as much as I had hoped.
First off, to make life more interesting, the plugin is one that is needed
for a role. I am trying to write an ansible cookbook to deploy Filebeat.
I was able to do this fairly easily on Chef (my first Chef project), but
Ansible is proving more cantankerous.
So, the problem I am trying to solve is simple, and requires aggregation of
values. I found a plugin that will read the contents of a file, and load
into into a variable value. I plan to modify this so I can send it a list
of files, and have it load the contents of ALL the files into a variable.
The problems I am currently struggling with are these:
Where does the plugin go within the role folder hierarchy, or does it need
to be global? I have found various contradictory sources that state it
goes in "plugins/lookup" or "lookup_plugins",or in Ansible root. Below
is my heirarchy, and the challenge is that I need to load a list of files
to load based on the default, membership in groups or instanceID. That
list will be built by checking for and loading any group.yaml, EC2ID.yaml
that exist. Once I have that list, I need to aggregate the values from the
corresponding files in the prospectors folders into a variable I can then
plug into my template.
Ansible doesnt handle aggregation in loops well. I am looking at one or
two plugins to do this. One would be a modification of the example that
loads a file into a variable to it takes a file list instead.
