私は基本的にRedhatでもDebianでもリモートホストから動的情報を取得し、それに応じてOSのバージョンに従ってhttpパッケージをインストールする特定のファイルを実行したいと思います。

[root@ansi1 ansible]# cat include.yml
---
 - hosts: all
   tasks:
   - name: Getting os info
     include_vars: "{{ ansible_os_family }}.yml"

   - include: setup-RedHat.yml
     when: ansible_os_family == 'RedHat'
[root@ansi1 ansible]#
[root@ansi1 ansible]#
[root@ansi1 ansible]#
[root@ansi1 ansible]# cat setup-RedHat.yml
---
 - hosts: all
   tasks:
   - name: htttp install
     yum: name=httpd state=present

アンサーブルプレイブックinclude.yml

間違い：

ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.

The error appears to have been in '/etc/ansible/setup-RedHat.yml': line 2, column 4, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

---
 - hosts: all
   ^ here
