# Pull the official Selenium Docker image
docker pull selenium/standalone-chrome:4.0.0-alpha-4

# Run the Selenium Docker container
docker run -d \
  --name selenium-grid \
  -p 4444:4444 \
  -v /dev/shm:/dev/shm \
  selenium/standalone-chrome:4.0.0-alpha-4

# Alternatively, if you want to run a grid in AWS
# 1. Create an AWS ECS cluster and service
# 2. Use the following Docker Compose file to define the service
version: '3'
services:
  selenium-grid:
    image: selenium/standalone-chrome:4.0.0-alpha-4
    ports:
      - "4444:4444"
    shm_size: 2g
    deploy:
      mode: replicated
      replicas: 1
      resources:
        limits:
          cpus: '0.5'
          memory: 2G

# 3. Run the AWS CLI command to start the service
aws ecs start-service --cluster your-cluster-name --service your-service-name
