In case you want to run ansible (or ansible-playbook) command against a set of hosts that makes sense only for one run, you can don't bother to create one-time inventory file, but simply define a comma-separated list of hosts as argument of --invertory option (or its short form that's simply -i) as follows:

ansible --inventory=myhost1,myhost2,myhost3 all -m setup -a 'filter=*name*'

(note that all in this command line stands for the target hostname)

If you have only one host to run your playbook against, your inventory string must ends with ,
