ansible - 多行模板 - Ansible 中的字符串转义

Question

我试图获得类似于本文的效果:https://gryzli.info/2017/12/21/ansible-debug-print-variables/

这意味着在我的情况下:

- name: Gather facts
  vars:
    msg: |
    "{{ansible_distribution}}"
    "{{ansible_distribution_major_version}}"
    "{{ansible_distribution_release}}"
    "{{ansible_distribution_version}}"

问题是如果没有引号，添加引号会引发错误。使用引号会引发相同的错误:

We could be wrong, but this one looks like it might be an issue with missing quotes. Always quote template expression brackets when theystart a value....

如何正确转义此多行字符串以便 Ansible 可以解析它？或者这种代码不再有效？

Q: "How do I correctly escape this multiline string so that Ansible can parse it?"

A:问题是块的缩进。引自 Example 8.3. Invalid Block Scalar Indentation Indicators

ERROR:

• A leading all-space line must not have too many spaces.
• A following text line must not be less indented.
• The text is less indented than the indicated level.

正确的语法是(带或不带引号)

  vars:
    msg: |
      "{{ansible_distribution}}"
      "{{ansible_distribution_major_version}}"
      "{{ansible_distribution_release}}"
      "{{ansible_distribution_version}}"
