Deploying with AWS Written by Jonas Schwartz

Note: This update is an early-access release. This chapter has not yet been updated to Vapor 4.

Amazon Web Services (AWS) is by far the largest Cloud provider today. It provides a number of service offerings which simplify the deployment and maintenance of applications. In this chapter, you’ll learn how to use a few of these to deploy a Vapor app.

Before starting

To perform the steps in this chapter, you must have an AWS account. If you don’t already have one, follow the instructions at https://aws.amazon.com/premiumsupport/knowledge-center/create-and-activate-aws-account/ to create one.

Setup your AWS instance

Your first step is to start an EC2 instance. EC2 is AWS Virtual Machine product. This gives you a plain Linux machine you can use to run your Vapor application.

Install Swift

To build your Vapor app, you must install Swift on your EC2 instance. The easiest way to install and update Swift on Ubuntu is to use the Vapor APT repository.

What is APT?

APT (Advanced Package Tool) is the default package manager for Debian-based Linux systems, like Ubuntu. The Vapor team maintains an APT repository for Swift and the Vapor Toolbox.

Install Swift from APT

To install Swift from the Vapor APT, enter the following commands:

# 1
wget -q https://repo.vapor.codes/apt/keyring.gpg -O- | \
  apt-key add -
# 2
echo "deb https://repo.vapor.codes/apt $(lsb_release -sc) main"\
  | tee /etc/apt/sources.list.d/vapor.list
# 3
apt-get update
# 4
apt-get install swift ctls

Setting up your application

To set up your application, you will first clone it from GitHub.

Setting up a PostgreSQL server

For your database, you will use Amazon Relational Database Service (RDS). This AWS database service is based on AWS S3 and can emulate a number of popular relational database systems including PostgreSQL.

Installing and configuring nginx

nginx is a popular web server, typically used as a proxy server in front of other web apps. For Vapor apps, this is useful because it provides additional features such as compression, caching, HTTP/2 support, TLS (HTTPS) and more.

Running your app as a system service

You want your app to run when your instance boots and to restart if it crashes due to a critical error. The easiest way to accomplish this is to integrate it as a system service. The versions of Linux that Swift — and, therefore, Vapor — supports use a service called systemd to accomplish this.

Where to go from here?

You now have the basics of how to set up a Vapor app on AWS. There are many more things AWS allows, such as scaling, IP pooling, automatic backups, replication and so on. Spend some time with the AWS documentation and tutorials to learn more.
