I am trying to deploy my node js application with docker but when I am running the docker compose it giving an error at the end. I saw some solution like

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password'

, but where to specify this query in the docker.

docker-compose.yml

version: '3'
services:
  db:
    build:
      context: .
      dockerfile: ./docker/Dockerfile-mysql
    container_name: mydb
    environment:
      - MYSQL_ALLOW_EMPTY_PASSWORD=yes
      - MYSQL_DATABASE=dbautokab
      - MYSQL_USER=root
      - MYSQL_PASSWORD=
    networks:
      - helicopter-network
    healthcheck:
      test: "exit 0"

  helicopter-api:
    build:
      context: .
      dockerfile: ./docker/Dockerfile-api
    depends_on:
      - db
    networks: ['helicopter-network']
    environment:
        - PORT=3000
        - DATABASE_HOST=db
        - DATABASE_PASSWORD=
        - EGG_SERVER_ENV=local
        - NODE_ENV=development
    ports:
      - "3000:3000"

networks:
  helicopter-network:
    driver: bridge
