ansible.builtin.nested lookup – composes a list with nested elements of other lists
Note
This lookup plugin is part of ansible-core
and included in all Ansible
installations. In most cases, you can use the short
plugin name
nested
even without specifying the collections:
keyword.
However, we recommend you use the FQCN for easy linking to the
plugin documentation and to avoid conflicting with other collections that may have
the same lookup plugin name.
