The big advantage of using Compose is you can define your application stack in a file, keep it at the root of. Docker Compose allows us developers to easily handle multiple docker containers at once by applying many rules which are declared in a docker-compose.yml file. With Compose, you can create a YAML file to define the services and with a single command, can spin everything up or tear it all down. In this tutorial we will discuss on how docker compose files work and file structure of docker compose.

The manual process that avoids using docker-compose works well and once you attach both containers (es and foodtrucks-web) to the same docker network foodtrucks-net, you can access es container from within foodtrucks-web with no problems. Docker compose is a great framework for deploying your production code in a short period of time.
