Ansible Display自定义错误消息“stat”

我想验证文件路径如果文件存在与否。我写下了下面的任务。Ansible Display自定义错误消息“stat”

- name: File Validation 
    stat: path={{src_file_path}}{{filename}} get_md5=yes 
    register: file 
- fail: msg="Whoops! File does not exist.!" 
    when: file.stat.exists == False

“失败”模块抛出下面的错误

TASK: [deploy-stack | fail msg="Whoops! File does not exist.!"] *************** 
failed: [192.168.36.128] => {"failed": true} 
msg: Whoops! File does not exist.! 

FATAL: all hosts have already failed -- aborting

我没有得到为什么失败模块是表现为它想。

谢谢Chandan，我想验证本地主机上的文件。如果文件存在，我会将它复制到远程服务器并验证校验和。在这种情况下，如果文件路径改变，我无法处理异常。 ansible正在“跳过”验证和文件复制任务。 – tgcloud

你可以简单地添加另一个条件，当它不存在时做任何你想做的事情，这样它就不会被跳过 - 更新了答案。 –
