Explain what Docker Compose is and what role it plays in container management?

Docker Compose is a tool for defining and running multi-container Docker applications. Using the docker-compose.yml file, you can describe the configuration of multiple containers, their networks, volumes, and dependencies.

The role of Docker Compose in container management:

• Allows running complex applications composed of multiple services with a single command.
• Simplifies the setup and scaling of services.
• Eases management of configurations and development environments.

Example of a simple docker-compose.yml:

version: '3'
services:
  web:
    image: nginx
    ports:
      - "80:80"
  db:
    image: postgres
    environment:
      POSTGRES_PASSWORD: example
