docker-compose: install

1. Preface
Compose is a tool for Docker cluster management. You can define a multi-container application in a file, then start your application with a single command, and it will automatically resolve the container dependencies, download the image, and start the application.
Docker Compose is a tool for orchestrating Docker containers. It defines and runs multi-container applications, and can start multiple containers with one command.


Using Compose is basically divided into three steps:


Dockerfile defines the running environment
of the application docker-compose.yml defines the services that make
up the application docker-compose up Starts the entire application
