How can I set up authentication for Selenium Grid using Docker Compose?

To set up authentication for Selenium Grid with Docker Compose, you can use the following steps: 1. Define your services in the docker-compose.yml file. 2. Use environment variables to set up username and password for the Selenium Hub. 3. Configure the Node services to use the same credentials.

Can you provide a sample docker-compose.yml file for this setup?

Sure! Here's a basic example:

version: '3'
services:
  selenium-hub:
    image: selenium/hub
    environment:
      - HUB_AUTH=enabled
      - HUB_USERNAME=your_username
      - HUB_PASSWORD=your_password
    ports:
      - "4444:4444"

  chrome:
    image: selenium/node-chrome
    environment:
      - NODE_MAX_SESSION=5
      - NODE_MAX_INSTANCES=5
      - HUB_HOST=selenium-hub
      - NODE_USERNAME=your_username
      - NODE_PASSWORD=your_password
    depends_on:
      - selenium-hub

What if I want to add more nodes or different browsers?

You can add more nodes by duplicating the node service in your docker-compose.yml file and changing the image to the desired browser, like selenium/node-firefox for Firefox. Just ensure each node has the same HUB_HOST, NODE_USERNAME, and NODE_PASSWORD.

Is there a way to test if the authentication is working?

Yes, you can test the authentication by trying to access the Selenium Grid UI at http://localhost:4444/grid/console. If prompted for credentials, your setup is working correctly.
