我在ansible剧本中得到了以下任务

- name: Check if default ssh user exist  
  shell: whoami  
  remote_user: "{{default_ssh_user_info.name}}"  
  ignore_errors: yes  
  register: results
目标是检查远程计算机上是否配置了用户
{{default\u ssh\u user\u info.name}
，如果不是，我将以根用户身份连接并使用以下任务创建它

但是，
ignore\u errors
似乎没有捕获错误。。。这是我唯一的剧本站。有没有办法抓住这种错误？是虫子吗

以下是错误消息：

FATAL: all hosts have already failed -- aborting
后续行动

我正在尝试以下解决方案：

  - name: Check if default ssh user exist
    shell: id -u {{ default_ssh_user_info.name }}
    remote_user: "{{ init_ssh_user_info.name }}"
    ignore_errors: yes
    register: results
    sudo: yes
    when: init_ssh_user_info.name is defined
我唯一的问题是SSH连接仍然失败，因为它找不到私钥。是否可以在Ansible中指定特定任务的私钥路径？我在文档中找不到它

这里的问题是，Ansible不会直接在您的任务中失败，而是在连接到主机时已经失败了。这是一个致命错误，您不能忽略此级别的错误

我知道你有三个选择

  • 以root用户身份运行任务（不一定，如果您确实知道存在另一个用户，则可以使用该用户），并检查该用户是否存在：

    - shell: id -u {{ default_ssh_user_info.name }}
  register: results
  sudo: yes
  • 通过shell任务创建您自己的ssh连接：

    - shell: ssh {{ default_ssh_user_info.name }}@{{ inventory_hostname }} whoami
  delegate: localhost
  register: results
但我想知道你为什么一开始就需要这样一张支票。当您使用Ansible时，它只会在用户不存在的情况下创建用户（呃…它怎么可能不存在；-）。如果您想根据用户是否刚创建而触发自己的操作，则可以注册该输出并检查
更改的
属性


- user: name={{ default_ssh_user_info.name }}
  sudo: yes
  register: user_created

- debug: msg="User was created"
  when: user_created | changed


请包括错误和命令执行结果。
