Docker Compose

Docker Compose is a console tool for running multiple containers using one command. It provides an easy way to manage and coordinate multiple containers, making it easier to build, test, and deploy complex applications. With Docker Compose, you can define your application’s services, networks, and volumes in a single YAML file, and then start and stop all services from the command line.

To use Docker Compose, you first need to define your application’s services in a docker-compose.yml file. This file should include information about the services you want to run, their configuration, and how they are connected. The file should also specify which Docker images to use for each service.

The docker-compose.yaml file is a central configuration file that’s used by Docker Compose to manage the deployment and running of applications. It is written in YAML syntax.

The structure of the docker-compose.yaml file is divided into several sections, each...
