ansible lineinfile 模块以匹配 variable_value

  • 772

如何通过 lineinfile 模块中的正则表达式参数匹配变量的值？

- name: emptyline before search
  lineinfile:
    dest: ~/file
    insertbefore: '^{{ search_text }}$'
    line: ''

我在上面尝试了单引号/双引号，它似乎不起作用

ansible search

    对于一个文件test.txt

    hello
something
test
hello
something

    运行一个测试剧本，比如

    ---
- hosts: localhost
  become: false
  gather_facts: false

  vars:

    BEFORE: "test"

  tasks:

  - name: Add line before
    lineinfile:
      path: test.txt
      insertbefore: '^{{ BEFORE }}$'
      line: ''

    结果输出为

    hello
something

test
hello
something

    预期的。
