Ansible - Including and Importing

include* vs. import*	( pre 2.4 only include existed and behaved differently)
import*	pre-processed when playbook is read
include*	processed when reached during playbook execution

Include playbooks inside master playbook (tasks/plays run in order ):

- import_playbook: webservers.yml
- import_playbook: databases.yml

Task files can be defined:

# common_tasks.yml
- name: placeholder foo
  command: /bin/foo
- name: placeholder bar
  command: /bin/bar

import or include task files:

tasks:
- import_tasks: common_tasks.yml
# or
- include_tasks: common_tasks.yml

Using variables with imports / includes:

tasks:
- import_tasks: wordpress.yml
  vars:
    wp_user: timmy
- import_tasks: wordpress.yml
  vars:
    wp_user: alice
- import_tasks: wordpress.yml
  vars:
    wp_user: bob

Using includes for handlers ( so you can share handlers between playbooks):

# more_handlers.yml
- name: restart apache
  service:
    name: apache
    state: restarted


handlers:
- include_tasks: more_handlers.yml
# or
- import_tasks: more_handlers.yml
