optimize playbook

[Alexey Lesovsky]

Hi all!

I write role for Ansible Galaxy, and have a little problem. I have 2 host groups and need execute different tasks for this groups. At this moment I doing it with the following configuration, this is the root playbook.yml

- hosts: all
  sudo: yes
  sudo_user: root
  vars_files:
    - 'defaults/main.yml'     # main configuration
    - 'defaults/repo.yml'     # repositories which must not be changed in normal case
  tasks:
  - include: 'tasks/install.yml'

- hosts: streaming-master
  sudo: yes
  sudo_user: root
  vars_files:
    - 'defaults/main.yml'
    - 'defaults/repo.yml'
  tasks:
  - include: 'tasks/configure-master.yml'
  - include: 'tasks/users.yml'
  - include: 'tasks/databases.yml'

- hosts: streaming-slaves
  sudo: yes
  sudo_user: root
  vars_files:
    - 'defaults/main.yml'
    - 'defaults/repo.yml'
  tasks:
  - include: 'tasks/configure-slaves.yml'

Аs you can see, there are many duplicate information (sudo/sudo_user/vars_files), how to avoid it?

Put in in ansible.cfg file, with contain default values for ansible. Like remote user or sudo. And many others :)
