ansible: Execute a command on a group of hosts by invoking command module with arguments.
$ ansible ${group} -m command -a '${my_command}'
try on your machine
This command is an example of using Ansible to execute a command on a group of hosts specified by the variable ${group}
.
Here's the breakdown of the command:
ansible
: This is the basic command to run Ansible.${group}
: This is a variable representing the group of hosts you want to target. You would replace${group}
with the actual group name, such asweb_servers
ordatabase_servers
.-m command
: This specifies the Ansible module to use, in this case, thecommand
module. Thecommand
module allows you to run arbitrary commands on the remote hosts.-a '${my_command}'
: This is the argument for thecommand
module. It specifies the command you want to execute on the remote hosts and is passed as a variable${my_command}
. You would replace${my_command}
with the actual command you want to run, such asls
orapt-get update
. The command should be enclosed in single quotes ('
) to preserve any special characters or variables within it.
So, when you run this command, Ansible will execute the specified command (${my_command}
) on the hosts in the specified group (${group}
).

never run a command you are not sure if it is safe.
