  springboot:
    build:
      context: ./
      dockerfile: ./Dockerfile
    image: springboot
    networks:

    ports:
      - "8081:8081"
      - "5005:5005"
    volumes:
      - "./springboot:/home/spring_curso"
    environment:
      - ADDITIONAL_OPTS=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005 -Xmx1G -Xms128m -XX:MaxMetaspaceSize=128m

o problema que ocorre e que quando dou o docker-compose up --build --force-recreate ele criar o db, adminer e executa e fica online mas quando chega no springboot e não consegue logar no mysql, alguem já teve esse problema, ou sabem de alguma alternativa?
