playlets are self-contained playbooks which are never intended to be
directly executed. They are only to be used as an 'include' from our other
playbooks.
All of these playbooks must have:
hosts: $parent_group
the general structure is:
playlet_name/
vars/vars.yml
files/myfile.conf
myfile2.conf.j2
handlers/handlers.yml
book.yml
template for book.yml
---
- name: give the play let a name
hosts: $parent_group
tags:
- playlet_tag_name
vars_files:
- vars/somefile.yml
tasks:
- name: my task
action: stuff which I do
