Ansible 包含基于条件的任务文件

Question

刚刚进入 ansible 并想知道您是否可以根据 --extra-vars 中传递的变量将文件包含在任务 main.yml 中？

示例；

main.yml -- 来自 role/tasks

# Upload latest json to s3
- include: upload-code.yml

playbook.yml -- 来自剧本

- name: Launch cloudformation stack
  hosts: 127.0.0.1
  connection: local
  roles:
    - launch.cloudformation

如您所见，playbook.yml 包含 role，main.yml 包含 upload-code.yml

如何根据如下条件

添加 upload-code.yml

ansible-playbook playbook.yml --extra-vars "include=upload"

Answer 1

您可以通过对包含任务应用 when 条件来执行此操作。

- include: upload-code.yml
  when:
    - include is defined
    - include == "upload"

或者，如果您有多个包含文件，您也可以使用 include 作为名称的一部分。

- include: "{{ include }}-code.yml"
  when: include is defined

Ansible include task files based on conditional
