Allow cors ERPNext docker setup in production

I have successfully installed ERPNext on GCP Ubuntu. However I have one issue where I have a custome mobile application and need to get data to the Mobile application through ERPNexts REST API Feature. All requests are blocked due to a cors policy, understand the documentation talks about adding a configuration of allow_cors to the site configuration but I seem to be unable to do this. When I try to setup that command to allow the cors, it fails.

Here is my compose file to for the docker setup.

Any help to guide me on how to allow the cors policy will be highly appreciated, thank you :slight_smile:

For wildcard

bench --site {site.name} set-config -p allow_cors \"*\"

For list of secured domains only:

bench --site {site.name} set-config -p allow_cors "[\"https://frappe.io\"]"

this image is incorrect. you need frappe/frappe-socketio image as websocket

Thank you so much @revant_one.
