Ansible shell和perl腳本失敗

Question

我想在使用Ansible的主機上調用Perl腳本。 Perl腳本必須由特定用戶「PresenceUser」執行。我看到的是，雖然Ansible報告沒有錯誤腳本未能執行和/或完成作業。

我已經添加到執行此操作的任務是這樣的。

- name: Extract out Presence Collector application [Failing] 
    shell: perl extract.pl PresenceCollector_{{ app_version }}.tbz 
    become_user: PresenceUser 
    args: 
    chdir: "{{ app_path }}" 
    tags: 
    - application_install 
    register: result 

- debug: var=result.stdout_lines 
    tags: 
    - application_install 

從Ansible結果表明該

調試輸出顯示什麼都沒有。

TASK [presencecollector : debug] *********************************************** 
task path: /home/vagrant/ansible/roles/presencecollector/tasks/main.yml:180 
ok: [pres7] => { 
    "result.stdout_lines": [] 
} 

如果我以PresenceUser身份登錄到該主機，則可以成功手動執行該命令。

我試着用Ansible「command」模塊，並得到了相同的結果。

我注意到的一點是，即使我指定了「shell」模塊，它表明模塊名稱是「command」？

有沒有一種方法可以進一步調試Ansible試圖執行命令時發生了什麼。

嘗試引用傳遞給shell模塊的整個值並將stderror重定向到stdout。例如：

- name: Extract out Presence Collector application 
    shell: "perl extract.pl PresenceCollector_{{ app_version }}.tbz 2>&1" 
    become_user: PresenceUser 
    args: 
    chdir: "{{ app_path }}" 
    tags: 
    - application_install 
    register: result
