# Example commands to configure the ansible controller:
#
# ubuntu@hamzy-dev:~$ cat << __EOF__ | sudo tee -a /etc/ansible/hosts
# # @BEGIN
# 192.168.0.15
# hamzy-test ansible_host=192.168.0.15
#
# [molteniron]
# hamzy-test
# # @END
# __EOF__
# ubuntu@hamzy-dev:~$ ansible molteniron -m ping
# hamzy-test | SUCCESS => {
#     "changed": false,
#     "ping": "pong"
# }
#
# Remember to add the controller's public ssh key to:
# ubuntu@192.168.0.15/24:/home/ubuntu/.ssh/authorized_keys
