dict object' 没有属性 'ansible_facts',同时检查 Ansible 中的主机是否可访问

问题描述

我有以下建议的剧本代码,以检查库存主机是否可访问。

---
- hosts: "{{ENV}}_*"
  user: "{{USER}}"
  tasks:

    - fail:
        msg: "Server is UNREACHABLE."
      when: hostvars[item].ansible_facts|list|length == 0
      with_items: "{{ ansible_play_hosts }}"

我在运行剧本时遇到以下错误:

TASK [] ****************************************
fatal: [remotehost.com]: FAILED! => {"msg": "The conditional check 'hostvars[item].ansible_facts|list|length == 0' failed. The error was: error while evaluating conditional (hostvars[item].ansible_facts|list|length == 0): 'dict object' has no attribute 'ansible_facts'\n\nThe error appears to have been in '/web/aes/admin/playbooks/restart.yml': line 9,column 10,but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n       - fail\n         ^ here\n"}

需要有关如何修复此错误的建议?
