Declarative db schema without local instance

I would like to use the supabase CLI to execute declarative schemas defined in my git repo to the cloud server. This does not seem to be possible?

I am running my project inside a devcontainer, an agentic coding best practice. Given I am a solo dev, I dont need to add the complexity of docker in docker etc. to have a local database as it does not add sufficient value. I think this is a very common situation - so requesting CLI support for this use case.
