Ansible : Playbook を利用する (include)
2021/06/16
 
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

[cent@dlp ~]$
mkdir tasks

[cent@dlp ~]$
vi tasks/included.yml
# タスクの部分のみの記述で OK

- name: General packages are installed
  yum:
    name: "{{ packages }}"
    state: present
  vars:
    packages:
    - tar
    - wget
    - unzip
  tags: General_Packages

[cent@dlp ~]$
ansible-playbook playbook_sample.yml --ask-become-pass

BECOME password:

[2] Playbook を他からインクルードする場合は、[import_playbook] を利用します。
[1] の例に加えて、[httpd] の起動状態を保つ Playbook をインクルードします。
[cent@dlp ~]$
vi playbook_sample.yml
- hosts: target_servers
  become: yes
  become_method: sudo
  tasks:
    - include: tasks/included.yml
# 他の Playbook をインクルード
- import_playbook: 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: present
  - name: httpd is running and enabled
    service:
      name: httpd
      state: started
      enabled: yes

[cent@dlp ~]$
