What is the purpose of Docker Compose?

The purpose of Docker Compose is to define and manage multi-container Docker applications. It allows developers to describe an entire application stack within a single file using YAML syntax, specifying all the service configurations, networks, and volumes required for the application. This makes it easy to start, stop, and manage the application as a whole with simple commands, rather than having to manage each container individually.

Docker Compose streamlines the process of setting up development environments, deploying applications, and ensuring that all the required components work together seamlessly. It is particularly useful in microservices architectures, where applications are composed of various interconnected services that need to communicate with each other.

The other options do not align with the core functionalities of Docker Compose. Monitoring Docker containers, converting applications across operating systems, and uninstalling Docker are tasks that fall outside the scope of what Docker Compose is designed to handle. By focusing on the orchestration of multiple containers, Docker Compose plays a crucial role in modern DevOps practices and container management workflows.
