Docker-Compose

Docker-compose is a tool used to run multi-container applications/services on a single host. The multi-container configuration setting can be done using a yaml file where requirements to deploy a service can be specified. Multiple container can be launched using a single command with help of the docker-compose.yml file. (https://docs.docker.com/compose/overview/)
