This project requires Python 3.
Note that as one, of many, considerations to scaling your web app that you should review the use of WEB_CONCURRENCY and Gunicorn. WEB_CONCURRENCY can be set to 3 for the Test/QA environment in order to set the number of Worker processes that Gunicorn will use to process requests. Test/QA usually can use a t2.small instance with 1 CPU core. # of Worker process was set using a formula of '(2 x $num_cores) + 1'.

export WEB_CONCURRENCY=3This repo is where our Bounty Snake lives, hunts and slithers. Of course our snake is of the python variety. Should you be unlucky enough to have crossed paths with a Blacktail then you are already aware of the venomous fangs, evil eyes and forked tongue that await you.

If you would like to persist the data between game turns logging to redis can be turned on in the settings.conf file.
Redis must be running on localhost. The easiest way to do this is to run the docker container.
docker run -d -p 6379:6379 redis
Logging is accomplished via standard Python logging. If running under Docker you will find logs under /var/logs/nginx/ and /var/logs/supervisor/. If running a Dockerized container under AWS Elastic Beanstalk with the template Dockerrun.aws.json deployment configuration you will find logs under the host system under /var/logs/containers/ and you will also be able to download these logs based on volume mounts in the Elastic Beanstalk Webapp Console in AWS.
