Robusta can send playbooks results to a local file (in JSON format).

Add this to your generated_values.yaml

- file_sink:
    name: file_sink
    file_name: optional\path\to\file.json

The file_name is the path to the output file where the playbook finding data will be written. It has to be a valid path with write permissions. This parameter is optional. If you omit it the stdout (console) will be used as default output.

Save the file and run

 helm upgrade robusta robusta/robusta --values=generated_values.yaml
