Docker Compose is a tool that is specifically designed for defining and managing multi-container applications. The purpose of Docker Compose is to simplify the process of deploying and orchestrating multiple containers that work together as part of a larger application.

With Docker Compose, you create a YAML file (commonly named docker-compose.yml) that outlines the services, networks, and volumes that your application needs. This comprehensive definition allows users to specify the configuration for each container, including images, build instructions, environment variables, ports, volumes, and various dependencies between containers. Once the configuration is set up, you can use a single command to build and start all the defined services simultaneously, making it easier to manage complex application stacks.

This is particularly beneficial in environments where multiple services need to interact with each other, such as a web server, database, and cache service working together. Docker Compose handles the orchestration of these components, ensuring they are properly configured and linked.

Other options do not accurately capture the primary function of Docker Compose. For example, creating and managing networks is an aspect of Docker networking capabilities but is not the main purpose of Docker Compose itself. Similarly, deploying single containers only is misleading, as Docker Compose is explicitly focused on multiple containers, making it ill-s
