Ansible : Playbook を利用する (include)2024/09/11

	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。

freebsd@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: tasks/included.yml

freebsd@dlp:~ $

mkdir tasks

freebsd@dlp:~ $

vi tasks/included.yml

# タスクの部分のみの記述で OK

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

freebsd@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。

freebsd@dlp:~ $

vi playbook_sample.yml

- hosts: target_servers
  become: yes
  become_method: sudo
  tasks:
    - include_tasks: tasks/included.yml
# 他の Playbook をインクルード
- import_playbook: httpd.yml

freebsd@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: apache httpd is installed
    pkgng:
      name: apache24
      state: present
  - name: apache httpd is running and enabled
    service:
      name: apache24
      state: started
      enabled: yes
