Refer to the ansible documentation at https://docs.ansible.com/ansible/latest/user_guide/index.html#getting-started

This playbook requires:

• ssh keys uploaded to the masternode for ansible to log in
• ansible to be installed on the controlling machine (can be your local machine or another server)
• a hosts file on the controlling machine that specifies the IP addresses, ssh ports and login usernames of the masternodes
• an ansible vault file on the controlling machine with the encrypted passwords that are needed for sudo

Command I use to run this playbook with ansible:

$ ansible-playbook -i hosts --ask-vault-pass update_dash_mns.yml -vv
