The easiest way to target a group of host is to sepcify it when you trigger
call your ansible-playbook command, to have it working properly you need to
target all hosts in the playbook itself,
# group-configure.yaml
- name: group-configure
hosts: all
tasks:
…
# /group-configure.yaml
Then run the playbook on the group of your inventory
ansible-playbook -l target_hosts group-configure.yaml
hope that help.
