How to use the keycloak latest tag instead of the legancy tag, in you docker-compose.

Hi everyone.

Some time ago, and after a long time, I was trying to use again a new keycloak version.
But I've had some problem to start my container with this compose:

version: '3.8'
volumes:
  postgres_data:
    driver: local
  keycloak_data:
    driver: local
networks:
  local:
    name: localhost
    external: true
services:
  postgres:
    image: 'postgres:latest'
    networks:
      - local
    volumes:
      - 'postgres_data:/var/lib/postgresql/data'
    environment:
      POSTGRES_DB: keycloak
      POSTGRES_USER: keycloak
      POSTGRES_PASSWORD: password
  keycloak:
    image: 'quay.io/keycloak/keycloak:latest'
    networks:
      - local
    environment:
      DB_VENDOR: POSTGRES
      DB_ADDR: postgres
      DB_DATABASE: keycloak
      DB_USER: keycloak
      DB_SCHEMA: public
      DB_PASSWORD: password
      KEYCLOAK_USER: admin
      KEYCLOAK_PASSWORD: admin123
    ports:
      - '8000:8080'
    depends_on:
      - postgres
  pgadmin4:
    image: 'dpage/pgadmin4:latest'
    environment:
      PGADMIN_DEFAULT_EMAIL: andremoriya@gmail.com
      PGADMIN_DEFAULT_PASSWORD: admin123
    networks:
      - local
    depends_on:
      - postgres
    ports:
      - '6543:80'
Enter fullscreen mode Exit fullscreen mode

I just wanted to see if this compose worked, but when I ran docker-compose, I received the following error.

Changing

So, in our compose, we must change and add a few simple configurations.

The admin environment variable in Keycloak has been changed from KEYCLOAK_USER and KEYCLOAK_PASSWORD to KEYCLOAK_ADMIN and KEYCLOAK_ADMIN_PASSWORD respectively.
And we must include the 'command: start-dev' in our compose.

After changing, our compose should look like this:

....
  keycloak:
    image: 'quay.io/keycloak/keycloak:latest'
    networks:
      - local
    environment:
      DB_VENDOR: POSTGRES
      DB_ADDR: postgres
      DB_DATABASE: keycloak
      DB_USER: keycloak
      DB_SCHEMA: public
      DB_PASSWORD: password
      KEYCLOAK_ADMIN: admin //Changed
      KEYCLOAK_ADMIN_PASSWORD: admin123 //Changed
    ports:
      - '8000:8080'
    command: start-dev // Added
    depends_on:
      - postgres
....
Enter fullscreen mode Exit fullscreen mode

After that, we can run again, and the console output should look like this.:

That's it.

That's something I've recently discovered.
