google/python-runtime

google/python-runtime is a docker base image that makes it easy to dockerize standard Python application.

It can automatically bundle a Python application and its dependencies with a single line Dockerfile.

It is based on google/python base image.

Create a Dockerfile in your python application directory with the following content:
```
  FROM google/python-runtime
```
Run the following command in your application directory:
```
  docker build -t app .
```

See the sources for google/python-hello based on this image.

The image assumes that your application:

has a requirements.txt file to specify its dependencies
listens on port 8080
either has a main.py script as entrypoint or defines ENTRYPOINT ["/env/bin/python", "/app/some_other_file.py"] in its Dockerfile

When building your application docker image, ONBUILD triggers:

Create a new virtualenv under the /env directory in the container
Fetch the dependencies listed in requirements.txt into the virtualenv using pip install and leverage docker caching appropriately
Copy the application sources under the /app directory in the container
