Docker container exits despite "ng serve --host 0.0.0.0"

Question

I'm trying to run an angular app inside a docker container. The docker container exits shortly after the command "ng serve --host 0.0.0.0" is executed.

docker-compose.yml:

services
  frontend:
    build:
      context: .
      dockerfile: ./docker/Dockerfile-frontend
    command: sh -c "cd public; npm install && npm run start"
    container_name: frontend-mol
    environment:
      - PORT=4200
    networks:
      - fullstack
    ports:
      - 4200:4200
    volumes:
      - ./:/app
    working_dir: /app

  networks:
    fullstack:
      driver: bridge

package.json:

"scripts" : {
    "start": "ng serve --host 0.0.0.0"
}

I did not alter the angular.json file. This is a fresh installation of Angular 17, I'm just trying to make a "hello world" app running in the container. What am I missing here?

The problem was the Node version indeed. Using Node v 18 in favour of v 16 solved the problem.
