Help me understand how to manage a local supabase setup

Hello!

I'm playing with Supabase docker deployment.

I create my local deployment using the CLI, with the

supabase start

supabase start

supabase start

supabase start command.

I would like to know:

How can I setup secrets? It seems that creating a .env has no effect
Are edge functions working with a local deployment?
Can I use the CLI tools with a docker deployment? I cannot generate an access token from my local Supabase studio, it gives me a 404 error.

In general, what doesn't work with docker deployments except the settings page in the studio?

Thanks
