动态 include

- name: Include tasks based on OS type
  include_tasks: "{{ ansible_os_family }}.yaml"

动态引入变量文件

- name: Include variables based on environment
  include_vars: "{{ lookup_vars }}.yaml"
  vars:
    lookup_vars: "{{ lookup('env', 'ENVIRONMENT') | default('dev', true) }}"

动态引入role

- name: Include roles based on a condition
  hosts: all
  tasks:
    - name: Include webserver role if the environment is production
      include_role:
        name: webserver
      when: environment == 'production'

引入playbook

---
- name: Main Playbook
  hosts: localhost
  vars:
    lookup_vars: "{{ lookup('env', 'ENVIRONMENT') | default('dev', true) }}"
  tasks:
    - name: Include environment-specific playbook
      include_playbook: "{{ lookup_vars }}.yaml"
