Hi there,
this Documentation should be helpful especially for docker https://www.keycloak.org/server/containers

To get started, I’ll give you my script for a small local test environment including postgress connectivity.

docker-compose.yml

# docker version
version: "3"

services:  
  Backend_Frontend:    
    image: quay.io/keycloak/keycloak:20.0.0

  postgres_svr: 
    image: postgres:10
    command: postgres -c 'max_connections=200' && postgres -c 'shared_buffers=24MB'    
    environment:
      # Environment Variables expecially for Postgres
      POSTGRES_DB: db_name
