Ansible: Ad-hoc commands

You need to run a single command on multiple machines? This can be achieved with ad-hoc commands by using the raw module.

ansible all -i hosts-inventory -m raw -a "yum install package-abc" --become

Parameters:

• -i inventory: specify the file containing the hosts definition

• -m raw module: specify the raw module, executing a command directly on the remote host

• -a CMD argument: the command that will be run, given as parameter to the module

• --become: run the command as a different user, in this case run with sudo
