Tic Tac Toe on DynamoDB

TicTacToe is a lightweight application that runs on Python and depends on two packages, Flask(2.2) and Boto3(1.21). You'll also need the boto3_alternator file from https://github.com/scylladb/alternator-load-balancing/blob/master/python/boto3_alternator.py. If you want in depth information about the application and DynamoDB check out Tic Tac Toe on DynamoDB.

Below are instructions that will help you launch the application. These instructions will also require you to have access to a terminal.

Note: May need administrative privileges for these installations

Installing Python

If you don't have Python installed by default, download Python (use v3.6+) by following the instructions on https://www.python.org/download/

Installing required dependencies:

Download/install pip (Follow the instructions here http://pip.readthedocs.org/en/latest/installing.html)

Once you have pip up to date and installed, clone this repo, cd to its dir and run:.

    pip3 install -r /path/to/requirements.txt

Configuring Tic Tac Toe

Once you have these dependencies set up, you will have to run the application with your own configurations.

The full list of options is as follows:

  python3 application.py [-h] [--config pathToConfig] [--mode (local | service)]
                        [--endpoint ENDPOINT] [--port dbPort] [--serverPort flaskPort]

Example:

  python3 application.py --mode local --endpoint $yourAlternatorIP

Run Alternator

You can easily get an Alternator instance started by running the following:

  docker run --name scylladb-alternator scylladb/scylla:latest --smp 1 --memory 512M --alternator-port 8000 --alternator-write-isolation always
  sleep 1m
  yourAlternatorIP="$(docker inspect --format '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' scylladb-alternator)"
  # then you can run the application.py passing variable $yourAlternatorIP
