Ansible Fileinline无法与循环一起使用 [英] Ansible fileinline not working with loop

问题描述

我正在尝试使用lineinfile在文件中添加或编辑多行，但无法正常工作.我正在使用以下没有运气的代码Ref: ansible:lineinfile中有几行?

I am trying to add or edit multiple lines in a file using lineinfile but not working. I am using below code with no luck Ref: ansible: lineinfile for several lines?

# vim /etc/ansible/playbook/test-play.yml 

- hosts: tst.wizvision.com
  tasks:
  - name: change of line
    lineinfile:
      dest: /root/test.txt
      regexp: "{{ item.regexp }}"
      line: "{{ item.line }}"
      backrefs: yes
      with_items:
      - { regexp: '^# line one', line: 'NEW LINE ONE' }
      - { regexp: '^# line two', line: 'NEW LINE TWO' }

错误:

# ansible-playbook test-2.yml

任务[换行] ********************************************* *****************

TASK [change of line] **********************************************************

致命:[localhost]:失败！ => {"failed":true，"msg":字段'args'的值无效，该值似乎包含未定义的变量.错误为:'item'未定义\ n \ n错误显示为已位于"/etc/ansible/playbook/test-2.yml"中:第3行第5列，但是\ n根据确切的语法问题可能\ n不在文件的其他位置.\ n \ n出现问题的行似乎是:\ n \ n任务:\ n-名称:更改行\ n ^这里\ n}

fatal: [localhost]: FAILED! => {"failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'item' is undefined\n\nThe error appears to have been in '/etc/ansible/playbook/test-2.yml': line 3, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n tasks:\n - name: change of line\n ^ here\n"}

推荐答案

您的with_items在任务中未正确缩进.

Your with_items is not indented correctly within the task.

with_items应该在模块级别，而不是作为模块本身的参数.在您的情况下，您要将with_items作为参数传递给lineinfile模块，而ansible抱怨说对于lineinfile模块没有参数作为with_items.

with_items should be at the level of the module, not as a parameter to the module itself. In your case, you are passing with_items as a parameter to lineinfile module, and ansible is complaining that there is no parameter as with_items for lineinfile module.

您的任务应如下所示-

tasks:
- name: change of line
  lineinfile:
    dest: /root/test.txt
    regexp: "{{ item.regexp }}"
    line: "{{ item.line }}"
    backrefs: yes
  with_items:
    - { regexp: '^# line one', line: 'NEW LINE ONE' }
    - { regexp: '^# line two', line: 'NEW LINE TWO' }
