如何在Ansible lineinfile模块中转义'＃'注释字符？

How can I escape characters in Ansible's lineinfile module?

如何在Ansible的lineinfile模块中转义字符?

Here's the line I want to insert on the server:

这是我要在服务器上插入的行:

EMAIL='hi@demo.com' # Server notification email address enter only 1 address

EMAIL='hi@demo.com'#服务器通知电子邮件地址只输入1个地址

But when I try the following, Ansible refuses to parse it due to YAML errors:

但是当我尝试以下操作时,Ansible由于YAML错误而拒绝解析它:

line="EMAIL='{{ email_address }}' # Server notification email address enter only 1 address"

line =“EMAIL ='{{email_address}}'#服务器通知电子邮件地址只输入1个地址”

I'm guessing it's because I have a strange combination of double quotes, single quotes, equal character and pound character.

我猜它是因为我有一个奇怪的组合,双引号,单引号,相等的字符和英镑字符。

The problem indeed is the # in your string - for whatever reason.

问题确实是你的字符串中的# - 无论出于何种原因。

Though you can easily prevent the parsing error by using this trick:

line="EMAIL='{{ email_address }}' {{ '#' }} Server notification email address enter only 1 address"

For longer form comments or for readability you could also add comments as vars:.

对于更长的表单注释或可读性,您还可以添加注释为vars:。

name: Do something
vars:
  comment: '# Server notification email address enter only 1 address'
lineinfile:
  ...
  line="EMAIL='{{ email_address }}' {{ comment }}"
