      MYSQL_USER: 'raw'
      MYSQL_PASSWORD: '123456789'
    volumes:
      - ./data/mysql:/var/lib/mysql

right after that on port 81 i can't login as admin and i get the error
login.bundle.js?v=2.2.3:25 POST http://1.1.1.1:81/api/tokens 502 (Bad Gateway)

Now this command
node --abort_on_uncaught_exception --max_old_space_size=250 index.js
Gives the error

[root@docker-dd466fd29d69:/app]# node --abort_on_uncaught_exception --max_old_space_size=250 index.js

i don't understand depends_on however in other hand i can show you a different way how to reach this with private static ip.
my yml

      config:
      - subnet: 172.55.0.0/16

Now that we've set a static ip for each container and we have the mysql ip 172.55.0.72 config file will be

{
  "database": {
    "engine": "mysql",

    "name": "nginx",
    "user": "raw",
    "password": "123456789",
    "port": 3306
  }
}

You can close the issue after you read, since the project doesn't have anything wrong and mysql has been told that it's needed to be installed manually by us just wanted to share a full yml template.
