ansible playbook 的变量的值如何在另一个 paybook 中使用？

Question

I have two different playbooks named as demo1.yml and demo2.yml .

In demo1.yml there is a play, returned values of play is stored in register variable named as results . variable results has following:

"volume_details": {
    "status": "Ready",
    "Id": "123456",
    "name": "test_volume"
}

I want to use the value of results.volume_details.Id and results.volume_details.name in one of the plays of another playbook demo2.yml .

Is there any way to do use values of variables from previous playbook to another upcoming playbooks. I want to appreciate your efforts in advance!!!

Answer 1

You can create a main playbook and import the others with import_playbook

---
  - import_playbook: demo1.yml
  - import_playbook: demo2.yml

If you do so it should be possible to use registered vars from the first playbook in tasks within the second playbook. With {{ results.volume_details }}

EDIT: To save a variable to a file you can use the copy module, with the parameter content=.

 - copy: 
     content="{{ variable }}" 
     dest=dest_file.yml

To load this file use the include_var module

- name: Include var of dest_file.yml into the new_var 
  include_vars:
    file: dest_file.yml
    name: new_var
