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

The below article will cover the intricacies of setting up databases and heroku in respect to a flask app. This is more like a memo and will have out of sequence instructions or solutions to errors so read thoroughly.
You'll need the packages

CREATE ROLE readaccess; | |
-- Grant access to existing tables | |
GRANT USAGE ON SCHEMA public TO readaccess; | |
GRANT SELECT ON ALL TABLES IN SCHEMA public TO readaccess; | |
-- Grant access to future tables | |

First install pip for Python2. Download the get-pip.py file from https://bootstrap.pypa.io/get-pip.py | |
$ cd <download location> | |
$ sudo -H python ./get-pip.py | |
Installing pip also installs Python3 | |
To run Python3 | |
$ python3 | |
Install pip3 by just executing the same file as in the step above, but this time using Python3 | |
$ sudo -H python3 ./get-pip.py |
