Ansible : Playbook を利用する#52015/04/22

	タスクや Playbook は他からインクルードすることができます。
[1]	タスクを他からインクルードする場合は、tasks 内に include: ～と記述します。

[cent@dlp ~]$

vi playbook_sample.yml

# tasks ディレクトリ配下の included.yml をインクルード

- hosts: target_servers
  become: yes
  become_method: sudo
  tasks:
    - include: tasks/included.yml
      vars:
        general_packages: vim-enhanced,wget,unzip

[cent@dlp ~]$

mkdir tasks

[cent@dlp ~]$

vi tasks/included.yml

# タスクの部分のみの記述でOK

# item は general_packages の値を参照

- name: General packages are installed
  yum: name="{{ item }}" state=installed
  with_items:
    - "{{ general_packages }}"
  tags: General_Packages

[cent@dlp ~]$

ansible-playbook playbook_sample.yml --ask-become-pass

[2]	Playbook を他からインクルードする場合の例です。タスクのインクルードとは記述する階層が異なります。以下は、[1]の例に加えて、httpd の起動状態を保つ Playbook をインクルードする例です。

[cent@dlp ~]$

vi playbook_sample.yml

- hosts: target_servers
  become: yes
  become_method: sudo
  tasks:
    - include: tasks/included.yml
      vars:
        general_packages: vim-enhanced,wget,unzip

# 他の Playbook をインクルード

- include: httpd.yml

[cent@dlp ~]$

vi httpd.yml

# 通常の Playbook と同様の書式で記述する

- hosts: target_servers
  become: yes
  become_method: sudo
  tasks:
  - name: httpd is installed
    yum: name=httpd state=installed
  - name: httpd is running and enabled
    service: name=httpd state=started enabled=yes

[cent@dlp ~]$
