Flask app that will get you up and running on AWS (also uses RDS as a database)

Deploying a Flask application in AWS: An end-to-end tutorial

This is the code that goes along with the detailed writeup here:

It's a simple Flask app that writes and reads from a database. It uses Amazon RDS for the database backend, but you can make things even simpler and use a local DB.

To tool around with the app directly, here's a quickstart guide.

Clone this repo to your local machine. In the top level directory, create a virtual environment:

$ virtualenv flask-aws
$ source flask-aws/bin/activate

Now install the required modules:

$ pip install -r requirements.txt

To play with the app right away, you can use a local database. Edit config.py by commenting out the AWS URL and uncomment this line:

SQLALCHEMY_DATABASE_URI = 'sqlite:///test.db'

Next run:

$ python db_create.py

And the tables are created. Now you can launch the app:

$ python application.py

And point your browser to http://0.0.0.0:5000

Using the top form, you can write to the database:

Using the bottom form, you can see the last 1 to 9 entires of the database in reverse chronological order:
