Ansible 文件内联不适用于循环

Question

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。我使用下面的代码没有运气参考：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' }

Ansible 错误：

# ansible-playbook test-2.yml

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

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"}

您的 with_items 在任务中的缩进不正确。

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，您将 with_items 作为参数传递给 lineinfile 模块，而 ansible 抱怨 lineinfile 模块没有 with_items 参数。

你的任务应该是这样的 -

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' }
