ansible.builtin.host_list – Parses a ‘host list’ string


This module is part of ansible-base and included in all Ansible installations. In most cases, you can use the short module name host_list even without specifying the collections: keyword. Despite that, we recommend you use the FQCN for easy linking to the module documentation and to avoid conflicting with other collections that may have the same module name.

New in version 2.4: of ansible.builtin


  • Parses a host list string as a comma separated values of hosts

  • This plugin only applies to inventory strings that are not paths and contain a comma.


# define 2 hosts in command line
# ansible -i ',' -m ping all

# DNS resolvable names
# ansible -i ', host2' -m user -a 'name=me state=absent' all

# just use localhost
# ansible-playbook -i 'localhost,' play.yml -c local
