CORS error when trying to access supabase from a docker container

Hello,

I would like to dockerize a Svelte app that uses Supabase Auth. I am running Supabase CLI locally and the API url is available at

http://localhost:54321

http://localhost:54321

To access this url from within the Docker container I use the

http://host.docker.internal:54321

http://host.docker.internal:54321

url (https://docs.docker.com/desktop/networking/#i-want-to-connect-from-a-container-to-a-service-on-the-host)

This approach however produces a CORS error when trying to use Auth - see attached screenshot.

I could not find a

cors

cors

parameter in the

config.toml

config.toml

settings file of Supabase CLI. How can I add/update CORS to include the

host.docker.internal

host.docker.internal

origin?

In general, what is the recommended practice for using Supabase locally together with a dockerized web app?

Many thanks for the help!
