Note: By default Ansible will use the same username as your current machine’s username. 

Ansible ad hoc command, python not installed on host
ansible -i realhosts host1 -m raw -a "uname -r" -u root

realhosts file:  
[web]  
  host1 ansible_ssh_host=12.123.456.789 
  
Ping a host (mybox) defined in your hosts file:
ansible -i hosts mybox -m ping --connection=local


Pass variable to command: -e
ansible-playbook -i hosts task.yml -e file_state=touch


2 ways of accessing localhost:
1. through ssh (slower)
2. directly (connection: local)!
