In this section, we will discuss the widely used container orchestration tool docker-compose. The docker-compose tool is a very simple, yet power tool and has been conceived and concretized to facilitate the running of a group of Docker containers. In other words, docker-compose is an orchestration framework that lets you define and control a multi-container service. It enables you to create a fast and isolated development environment as well as orchestrating multiple Docker containers in production. The docker-compose tool internally leverages the Docker Engine for pulling images, building the images, starting the containers in the correct sequence, and making the right connectivity/linking among the containers/services based on the definition given in the docker-compose.yml file.
