keycloak with postgres

Hi, I'm running my application, postgres and keycloak in docker. I have 2 queries: 1. Is it possible to connect keycloak with postgres to store keycloak data and configurations? If yes, could you please provide me the steps or a link to the right documentation? 2. Is there any way to retain keycloak data using docker-compose.yml without any database, so that everytime I spin up docker, keycloak data and configurations are not lost?

Thanks in advance!
