Question

我有以下剧本，它仅在一台服务器上失败，并且在所有服务器上都没有任何错误

---
- hosts: user_host
  tasks:
  - name: check sdf user exists
    command: grep -Fq "sdf" /etc/passwd
    register: user_sdf_exist
    ignore_errors: True
    changed_when: False

 - name: check authorized_keys file exits
    stat: path=/home/sdf/.ssh/authorized_keys
    register: authorized_keys_file
    when: user_sdf_exist.rc == 0

关注是我收到的错误

fatal: [xxx.xxx.xxx.xxx]:FAILED! => {"failed": true, "msg": "The conditional check 'user_sdf_exist.rc == 0' failed. The error was: error while evaluating conditional (user_sdf_exist.rc == 0): 'dict object' has no attribute 'rc'\n\nThe error appears to have been in '/home/sdf/bin/configs/ansible/playbooks/roles/ansible_pub_key_for_sdf/tasks/main.yml': line 8, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: check authorized_keys file exits\n  ^ here\n"}

但是，仅针对该主机运行该Playbook时，该Playbook会通过并返回user_sdf_exist.rc ==0。我们拥有一个cron，它将在所有主机上每隔一小时运行一次此Playbook，在此期间，Playbook仅在此主机上失败一位主持人。

输出

        "changed": false, 
        "cmd": [

您需要使用when: user_sdf_exist.rc == 0

条件检查“ user_sdf_exist.rc == 0”失败
