What is Docker Compose?
A tool for defining and running multi-container Docker applications using YAML.
Docker Compose lets you define multi-container applications in a docker-compose.yml file. You specify services (containers), their images, environment variables, ports, volumes, networks, and dependencies. Running 'docker compose up' starts all services in the right order. It's ideal for local development and testing. Health checks with 'depends_on: condition: service_healthy' ensure services start in the correct order.
