How to remove the line breaker character '\n' from the result of lookup() module in Ansible?
提问by Nishant Singh
I am using [file lookup] which reads the whole file and stores the content in a variable. My play looks something like this:
我正在使用 [file lookup] 读取整个文件并将内容存储在变量中。我的游戏看起来像这样：
- name: Store foo.xml contents in a variable
set_fact:
foo_content: "{{ lookup('file', 'foo.xml' ) | replace('\n', '')}}"
So the above code reads the foo.xmlfile and stores it in the variable, but the problem is when the foo.xmlhas line breaks in it, it also includes the line break in the variable.
所以上面的代码读取foo.xml文件并将其存储在变量中，但问题是当其中foo.xml有换行符时，它还包括变量中的换行符。
My foo.xmlis this file:
我的foo.xml是这个文件：
<?xml version="1.0" encoding="utf-8"?>
<initialize_param>
<secrets>
<my_secret id="99">3VMjII6Hw+pd1zHV5THSI712y421USUS8124487128745812sajfhsakjfasbfvcasvnjasjkvbhasdfasgfsfaj5G8A9+n8CkLxk7Dqu0G8Jclg0eb1A5xeFzR3rrJHrb2GBBa7PJNVx8tFJP3AtF6ek/F/WvlBIs2leX2fq+/bGryKlySuFmbcwBsThmPJC5Z5AwPJgGZx</my_secret>
</secrets>
</initialize_param>
The output removes line break \n but also incudes the tabs \r & \t
输出删除换行符 \n 但也包括制表符 \r & \t
I need to got rid of the \n, need to get rid of extra formatting too (\r & \t), Moreover after the replace filter I get the error while firing a DB Update query as
我需要摆脱\n, 也需要摆脱额外的格式 (\r & \t)，而且在替换过滤器之后，我在触发数据库更新查询时出现错误
stderr: /bin/sh: 1: cannot open ?xml: No such file

You can do that with the replacefilter?
你可以replace用过滤器做到这一点吗？
contents: "{{ lookup('file', '/etc/foo.txt') | replace('\n', '')}}"
