ansibleのhandlerは便利なのですが、想定通り動かない場合にデバッグが難しいです。
サンプル
handlersは、notifyで通知された名前のhandlerを実行します。複数のタスクを実行する方法が分かりません...
handlerでシェルを起動する際、結果はどうあれ、出力を記録したかったのですが... handlerの２つ目のdebugは、普通に動きませんでした。
$ cat site.yml
---
- hosts: appservers
tasks:
- shell: ls
notify: aaa
handlers:
- name: aaa
shell: ls -l
register: result
- debug: var="result.stdout_lines"
$ ansible-playbook -i hosts site.yml
PLAY ***************************************************************************
TASK [setup] *******************************************************************

RUNNING HANDLER [aaa] **********************************************************

PLAY RECAP *********************************************************************
appserv1 : ok=3 changed=2 unreachable=0 failed=0
$
とりあえず...
-vvオプションでとりあえず実効結果は確認できますが、分かりにくい...
$ ansible-playbook -i hosts site.yml -vv
Using /home/vagrant/.ansible.cfg as config file
1 plays in site.yml
