ansible.builtin.nested – composes a list with nested elements of other lists

Note

This module is part of ansible-base and included in all Ansible installations. In most cases, you can use the short module name nested 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 1.1: of ansible.builtin
