Ansible - 将注册的变量保存到文件 [英] Ansible - Save registered variable to file

问题描述

如何将已注册的变量保存到文件中?我从教程:

How would I save a registered Variable to a file? I took this from the tutorial:

- hosts: web_servers

  tasks:

     - shell: /usr/bin/foo
       register: foo_result
       ignore_errors: True

     - shell: /usr/bin/bar
       when: foo_result.rc == 5

我如何将 foo_result 变量保存到文件中，例如foo_result.log 使用 ansible?

How would I save foo_result variable to a file e.g. foo_result.log using ansible?

推荐答案

感谢 tmoschou 将此评论添加到过时的接受答案:

Thanks to tmoschou for adding this comment to an outdated accepted answer:

As of Ansible 2.10, The documentation for ansible.builtin.copy says: 

If you need variable interpolation in copied files, use the
ansible.builtin.template module. Using a variable in the content field will
result in unpredictable output.

有关详细信息，请参阅this 和 说明

原答案:

您可以使用带有参数 content= 的 copy 模块.

You can use the copy module, with the parameter content=.

我在这里给出了完全相同的答案:将变量写入Ansible 中的一个文件

I gave the exact same answer here: Write variable to a file in Ansible

在您的情况下，您似乎希望将此变量写入本地日志文件，因此您可以将其与 local_action 符号结合起来:

In your case, it looks like you want this variable written to a local logfile, so you could combine it with the local_action notation:

- local_action: copy content={{ foo_result }} dest=/path/to/destination/file
