What is the use of Docker Compose?

Docker Compose is primarily used to define and run multi-container Docker applications. This tool allows developers to configure their applications using a YAML file where you can specify the services, networks, and volumes required for running the application. With Docker Compose, you can easily spin up and manage multiple containers that work together as a single application unit.

For instance, when building a web application, you might have separate containers for the web server, database, and caching system. Docker Compose enables you to orchestrate these containers smoothly, ensuring that they can communicate with each other according to the specifications laid out in the configuration file. This makes it significantly easier to set up and tear down complex applications with multiple interdependent components, which can save time and reduce errors during the development and deployment processes.

By focusing on the definition and management of these multi-container setups, Docker Compose plays a crucial role in streamlining development workflows and supporting containerized applications.
