Note: This update is an early-access release. This chapter has not yet been updated to Vapor 4.
Docker is a popular containerization technology that has made a huge impact in the way applications are deployed. Containers are a way of isolating your applications, allowing you to run multiple applications on the same server.
Using a container, instead of a full-fledged virtual machine, allows your containerized applications to share more of the host machine’s resources. In turn, this leaves more resources for your application to use rather than consuming them to support the virtual machine itself.
Docker can run almost anywhere, so it provides a good way to standardize how your application should run, from local testing to production.
This chapter will also show you how to use Docker Compose. Docker Compose is a way to specify a list of different containers that work together as a single unit. These containers share the same virtual network, making it simple for them cooperate with each other.
For example, with Docker Compose, you can spin up both your Vapor app and a PostgreSQL database instance with just one command. They can communicate with each other but are isolated from other instances running on the same host.
Setting up Vapor and PostgreSQL for Development
Begin by setting up a simple development configuration to test your app in a Linux environment. To facilitate debugging any problems that arise, this will be a much simpler configuration than you’ll use in production.

There are several changes you can make to your Docker configuration to simplify managing your app in a production environment. In this section, you’ll split your app into a “builder” container and a production image. You’ll also configure the PostgreSQL container to save its database in your host’s file system, making your data persist across changes to your app and its configuration.

You’ve seen some basic recipes for how to run your app in a Docker environment. Because Docker is so flexible, these recipes only scratch the surface of the possibilities available to you. For example, you might want to allow your app to save uploaded files in the host’s file system. Or, you might want to configure the app to run behind an nginx proxy server to get secure HTTPS access.
