Ansible 任務創建選項問題

我想編寫一個 Ansible 劇本以僅在不存在特定包時安裝包，因此當/tmp/hosted文件存在時安裝不應繼續，但它失敗了：

---
- hosts: all
  sudo: yes
  tasks:
  - name: Ensure NTP (for time synchronization) is installed.
    yum:  name=ntp state=present
    args:
     creates: "/tmp/hosted"

錯誤：

[root@ns0 ansible]# ansible-playbook creates.yml -l ansi2
[DEPRECATION WARNING]: Instead of sudo/sudo_user, use become/become_user and make sure become_method is 'sudo' (default).
This feature will be removed in
a future release. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.

PLAY [all] ***********************************************************************************************************************************************

TASK [Gathering Facts] ***********************************************************************************************************************************
ok: [ansi2]

TASK [Ensure NTP (for time synchronization) is installed.] ***********************************************************************************************
fatal: [ansi2]: FAILED! => {"changed": false, "failed": true, "msg": "Unsupported parameters for (yum) module: creates. Supported parameters include: conf_file,disable_gpg_check,disablerepo,enablerepo,exclude,install_repoquery,installroot,list,name,skip_broken,state,update_cache,validate_certs"}
       to retry, use: --limit @/etc/ansible/creates.retry

PLAY RECAP ***********************************************************************************************************************************************
ansi2                      : ok=1    changed=0    unreachable=0    failed=1

這將起作用

---
- hosts: all
 become: yes
 tasks:
   - name: Check existence of /tmp/hosted
     shell: test -e /tmp/hosted
     register: hostedfile
     ignore_errors: yes

   - name: Ensure NTP (for time synchronization) is installed.
     yum:  name=ntp state=present
     when: hostedfile.rc != 0
