Docker Compose
Docker Compose is based on an older orchastration tool called ‘Fig2.’ The idea of Fig was to make it easy to define full-stack applications in a single configuration file yet still help maintain the “one process per application” design of Docker. Docker Compose extends this idea into an official tool that will allow you to define how applications are structured into Docker containers while bundling everything up into an easy-to-deploy configuration.
Compose will read a file and build the necessary docker run commands that we need, in the proper order, to deploy our application. Since you should understand how all of this works from a manual process, Compose will just make the work you have done thus far much, much easier.
Compose starts with a docker-compose.yml file which contains all of the information on each container inside of an application, and how it should be configured.

To boot up a Compose configuration, go into the directory containing the docker-compose.yml file, which in our case is in the root directory of our application. We can boot the entire configuration using docker-compose -d up, and we should see something similiar to the following:
