services:
  selenium-hub:
    image: selenium/hub:4.0.0
    ports:
      - '4444:4444'
  chrome:
    image: selenium/node-chrome:4.0.0
    depends_on:
      - selenium-hub
    environment:
      - HUB_HOST=selenium-hub
  firefox:
    image: selenium/node-firefox:4.0.0
    depends_on:
      - selenium-hub
    environment:
      - HUB_HOST=selenium-hub

This sets up a Selenium Grid with a hub and nodes for Chrome and Firefox.
