ansible.builtin.from_yaml filter – Convert YAML string into variable structure

Note

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

Synopsis

  • Converts a YAML string representation into an equivalent structured Ansible variable.

  • Ansible automatically converts YAML strings into variable structures in most contexts, use this plugin in contexts where automatic conversion does not happen.
