How to get Apache Airflow running on a bare AWS EC2 node

Amazon Managed Workflows for Apache Airflow (AWS MWAA) is prohibitively expensive for someone tinkering around on a personal account, and unprepared to pay a few hundred dollars a month at a minimum for their smallest environment. Here are the commands I used to get it running on Ubuntu 20.

Prepare the box

sudo apt-get update

sudo yum update -y

# install Docker
# RE: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/docker-basics.html
sudo amazon-linux-extras install docker
sudo service docker start
sudo usermod -a -G docker ec2-user

# install docker-compose
# RE: https://docs.docker.com/compose/install/
