services:
  database:
    image: mysql:8.0.15
    environment:
      MYSQL_ROOT_PASSWORD: password
      MYSQL_DATABASE: dbname
    volumes:
      - databasevolume:/var/lib/mysql
    networks:
      - databasenetwork
    deploy:
      mode: replicated
      replicas: 1
      labels: [ database=MYSQL_DATABASE ]


  soofybackendservice:
    image: tomcatsoofybackend:latest
    #build:
    #  context: ./onlineshopping/soofy-trade
    #  dockerfile: Dockerfile
    environment:
      mysqlhost: shop_database

    depends_on:
      - database
    networks:

The proper URL for communication between services (ex. tomcatsoofyfrontend calling the soofybackendservice) is the name of the service in the docker-compose. In your case it's soofybackendservice, therefore the endpoit is http://soofybackendservice:8080/api/departments

If your application is calling the endpoint from the remote browser/host, then you need to call http://<<ip or the domain name of docker host>>:81/api/departments.

Angular is likely making client side calls. You need to expose your api and configure the URL accordingly. You'll likely need to specify localhost in your API url.
