when i build with this docker-compose the app can see the database and interact with it, but i cannot access the db with dbeaver or similar applications over the internet, how do i expose the database so that i can connect to it via dbeaver or directly from the outside.

this is the error:

Could not connect to myip here:3306 : A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
