docker-compose

Docker Compose is a tool for defining and running multi-container Docker applications. It allows you to define your application’s services, networks, and volumes in a single YAML file, and then spin up your entire application with a single command. It simplifies the process of managing complex, multi-container application environments by allowing you to declare and configure all of your application’s dependencies in a single file, and then launch and manage them with a single command. With Docker Compose, you can easily scale your application up or down, manage multiple environments (e.g. development, staging, production), and make changes to your application's configuration without having to manually update each container.
