Question

我写了一个ansible任务来生成具有相同模板块但具有一些不同属性值的单个文件。该任务能够按预期生成新文件，但在每个块的开头添加“False”。

这是我的代码：

- name: Test to generate config file
  hosts: localhost
  tasks:
    - name: Blockfile test
      blockinfile:
        path: blockfile_test
        create: yes
        marker: no
        insertafter: EOF
        content: "{{ lookup('template', 'blockfile_template') }}"
      with_items:
        - One
        - Two
        - Three

模板：

This is test to generate new file
        Count # {{ item }}

生成的文件：

False
This is test to generate new file
        Count # One
False
This is test to generate new file
        Count # Two
False
This is test to generate new file
        Count # Three
False

ansible命令输出：

$ ansible-playbook test.yml

PLAY [Test to generate config file] *************************************************************************************************************************

TASK [Gathering Facts] **************************************************************************************************************************************
ok: [localhost]

TASK [Blockfile test] ***************************************************************************************************************************************
changed: [localhost] => (item=One)
changed: [localhost] => (item=Two)
changed: [localhost] => (item=Three)

PLAY RECAP **************************************************************************************************************************************************
localhost                  : ok=2    changed=1    unreachable=0    failed=0

想要生成没有“False”字符串的文件。

Answer 1

blockinfile模块不能在没有标记线的情况下工作并且要使此模块正常工作，$("button.close").closest("panel").find(".panel-body").hide();选项必须包含要用marker / {mark}替换的BEGIN字，以便随后的Ansible运行可以是幂等的。

正确使用END可能是：

blockinfile

结果将是：

- name: Blockfile test
  blockinfile:
    path: blockfile_test
    create: yes
    marker: "; {mark} block for item {{ item }}"
    insertafter: EOF
    content: "{{ lookup('template', 'blockfile_template') }}"
  with_items:
    - One
    - Two
    - Three

P.S。并且您可能不希望使用; BEGIN block for item One This is test to generate new file Count # One ; END block for item One ; BEGIN block for item Two This is test to generate new file Count # Two ; END block for item Two ; BEGIN block for item Three This is test to generate new file Count # Three ; END block for item Tree来生成配置，只需在内部使用一些循环制作一些config.j2模板以迭代您的项目并调用blockinfile模块一次。

将标记设置为＆＃34;＆＃34;，它将在块的开头添加空行

- name: Blockfile test
  blockinfile:
    path: blockfile_test
    create: yes
    marker: ""
    insertafter: EOF
    content: "{{ lookup('template', 'blockfile_template') }}"
  with_items:
    - One
    - Two
    - Three

输出：

This is test to generate new file
        Count # One

This is test to generate new file
        Count # Two

This is test to generate new file
        Count # Three

在块文件模块的块开始处添加“False”
