ansible

Manage groups of computers remotely over SSH. (use the `/etc/ansible/hosts` file to add new groups/hosts).

Some subcommands such as `ansible galaxy` have their own usage documentation.

• List hosts belonging to a group:

ansible {group} --list-hosts

• Ping a group of hosts by invoking the ping module:

ansible {group} -m ping

• Display facts about a group of hosts by invoking the setup module:

ansible {group} -m setup

• Execute a command on a group of hosts by invoking command module with arguments:

ansible {group} -m command -a '{my_command}'

• Execute a command with administrative privileges:

ansible {group} --become --ask-become-pass -m command -a '{my_command}'

• Execute a command using a custom inventory file:

ansible {group} -i {inventory_file} -m command -a '{my_command}'

• List the groups in an inventory:

ansible localhost -m debug -a '{var=groups.keys()}'
