ansible.builtin.regex test – Does string match regular expression from the start

Note

This test plugin is part of ansible-core and included in all Ansible installations. In most cases, you can use the short plugin name regex 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 test plugin name.
