如何从用户输入添加用户动态条目以及库存文件的动态条目？

Question

---
- hosts: localhost
  become: yes
  gather_facts: no
  tasks:
    - name: delete file
      ignore_errors: yes
      file:
        state: present
        path: /root/ansible/inventory
  vars_prompt:
    - name: server_name
      prompt: "Enter the server name:"
      private: false
  tasks:
    - name: Add user input to file
      lineinfile:
        path: /root/ansible/inventory
        line: "{{ server_name }}"
        force: no
      delegate_to: localhost

但是我想用角色，我不能用

vars_prompt

ansible 不会拿
