When running ansible commands, specific hosts are addressed by wildcard or group name.
The default pattern is '*', meaning all ansible hosts.
This is required for all ansible commands.

ssh-agent bash
ssh-add ~/.ssh/id_rsa.pub

ansible -p "atlanta-web*" -f 10 -n command -a "/sbin/reboot"

To just transfer a file directly to many different servers:

To use templating, first run the setup module to put the template variables you would
like to use on the remote host. Then use the template module to write the
files using the templates. Templates are written in Jinja2 format.
ansible -p webservers -n setup -a "favcolor=red ntp_server=192.168.1.1"
ansible -p webservers -n template -a "src=/srv/motd.j2 dest=/etc/motd"
