Using set-up facts before doing tasks

[변규섭]

Hello fellas. 

I'm new 'bout Ansible and English as well

I'v tried to use var_prompt module in my yml file. 

and now i am stuck by it.

I wanna show my remote's ip address when my prompt is shown up

but as far as i know, i can't use vars_prompt with task.

This is my yml as below.

###########################################################

---

- hosts: all

  remote_user: root

  vars_prompt:

      - name: "check_it"

        prompt: "Are you sure that you wanna update it? '{{ansible_host}}' "

        default: "Default is 'no'"

        private: no

  tasks:

     - include: "./vios.yml"

       when: check_it == "yes" 

###############################################################

and what i want to is 

##########################################################

---

- hosts: all

  remote_user: root

  tasks:

    

  vars_prompt:

      - name: "check_it"

        prompt: "Are you sure that you wanna update it? '{{ansible_host}}' "

        default: "Default is 'no'"

        private: no

     - include: "./vios.yml"

       when: check_it == "yes"
