UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.
Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/
sudo amazon-linux-extras install docker
sudo service docker start
TL|DR: Use this to easily deploy a FastAI Python model using NodeJS.
You've processed your data and trained your model and now it's time to move it to the cloud.
If you've used a Python-based framework like fastai to build your model, there are several excellent solutions for deployment like Django or Starlette. But many web devs prefer to work in NodeJS, especially if your model is only part of a broader application.
My friend Navjot pointed out that NodeJS and Python could run together if we could send remote procedure calls from NodeJS to Python.
