Installation

You probably want the activerecord-postgres_enum gem, because it adds some good stuff for your migrations and allows you to keep using the schema.rb (instead of switching to a schema.sql:

gem 'activerecord-postgres_enum'

Your migration would then look like this:

class AddCountryToCities < ActiveRecord::Migration[5.2]

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/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start
