What is Docker Compose primarily used for?

Docker Compose is primarily utilized for defining and running multi-container Docker applications. It allows developers to configure multiple services that can work together in an application using a single YAML file. This file specifies all the services, networks, and volumes required for the application, making it easier to manage complex applications that consist of different interconnected containers.

With Docker Compose, users can streamline the orchestration of containers, ensuring that they start, stop, and communicate with each other seamlessly. This is particularly useful in development and testing environments where applications may depend on several different services, such as databases, caches, or web servers running in separate containers. By simplifying the setup process, Docker Compose enhances productivity and facilitates a smoother workflow when deploying multi-container applications.
