docker-compose

Docker Compose is a tool that allows you to define and run multi-container Docker applications. It uses a YAML file to define the services, networks, and volumes required for your application, and then starts and stops all the containers as a single unit.

With Docker Compose, you can easily spin up multiple containers that work together to create a complete application. For example, you could define a web server container, a database container, and a caching container, and then use Docker Compose to start all three containers at once.

Docker Compose also allows you to manage the configuration of your containers and easily scale your application up or down as needed. It is a powerful tool for managing complex applications and making them more portable and easy to deploy.
