# The Google App Engine python runtime is Debian Jessie with Python installed

# libraries. The source is on github at:

# Create a virtualenv for the application dependencies.
# If you want to use Python 3, add the -p python3.4 flag.
RUN virtualenv /env

# Set virtualenv environment variables. This is equivalent to running
# source /env/bin/activate. This ensures the application is executed within
# the context of the virtualenv and will have access to its dependencies.

# Kinto Example

This is a basic example of running Mozillas [Kinto](https://github.com/Kinto/kinto/blob/master/docs/index.rst)
on Managed VMs. Kinto provides a framework to sync JSON data across many devices and provide push notifications.
Thius example uses a custom runtime to install Kinto and edit the config to run it on port 8080, which is the port that
the base Docker image is expecting.

Since Kinto is being imported as a Python library and run as-is, no additional code is necessary.

Note that this is using Kinto's basic in-memory backend. As such, the instances are tied to 1. A production
version of Kinto would use a PostgreSQL database and Redis cluster, which would allow scaling to many instances.

If you are interested in seeing this example expanded to use PostgreSQL, you can file an Issue on the Issue
Tracker, or submit a Pull Request if you've accomplished it yourself.
