Hi all,

I have my principal playbook with this content :

- hosts: all  
become: no  
gather\_facts: no  
roles:
- role

I have on file with content :

my\_host\_1 ansible\_user: my\_user

my\_host\_2 ansible\_user: my\_user

I want that when i run my task, ansible execute only on my\_host\_1  
and when ansible fish execut task, he execut in second host of my inventory “my\_host\_2”

Someone have an idea please ?

Thanks community Ansible !!! 😉

Regards,
