How to pass database parameters to keycloak 20 docker?-CodePudding

I am trying to setup containers with keycloak postgres, but as long as the KC_DB en variable is set to postgres, then KC_DB_HOST nor KC_DB_URL seems to have any effect, and he startup fails with can't connect to localhost:5432.

Here is the docker-compose.yml :

services:
  
  db-keycloak:
    image: postgres:latest
    volumes:
      - "./_me_data/db-keycloak:/var/lib/postgresql/data"
    environment:
      POSTGRES_DB: keycloak
      POSTGRES_USER: keycloak
      POSTGRES_PASSWORD: keycloak
 
  keycloak:
    image: quay.io/keycloak/keycloak:latest
    ports:
      - "8082:8080"
    command: start-dev
    environment:
      KC_DB: postgres
      # KC_DB_URL=jdbc:postgres://db-keycloak:5432/keycloak
      KC_DB_HOST: db-keycloak
      KC_DB_USERNAME: keycloak
      KC_DB_PASSWORD: keycloak
      KEYCLOAK_ADMIN: root
      KEYCLOAK_ADMIN_PASSWORD: oooo

Replace KC_DB_HOST with KC_DB_URL_HOST (see Docs)
