This repository contains the source for the gcr.io/google_appengine/pythondocker base image. This image can be used as the base image for running applications on Google App Engine Flexible, Google Container Engine, or any other Docker host.

This image is based on Debian Jessie and contains packages required to build most of the popular Python libraries. For more information about this runtime, see the documentation.

When using App Engine Flexible, you can use the runtime without worrying about docker by specifying runtime: python in your app.yaml:

runtime: pythonvm: trueentrypoint: gunicorn -b :$PORT main:appruntime_config: # You can also specify 2 for Python 2.7python_version: 3

If you want to use this runtime as a base and customize it, you can generate a Dockerfile using the Cloud SDK:

gcloud beta app gen-config --custom 

You can then modify the Dockerfile and .dockerignore as needed for you application.

For other docker hosts, you'll need to create a Dockerfile based on this image that copies your application code, installs dependencies, and declares an command or entrypoint. For example:

FROM gcr.io/google_appengine/python # Create a virtualenv for dependencies. This isolates these packages from # system-level packages. RUN virtualenv /env # Setting these environment variables are the same as running # source /env/bin/activate. ENV VIRTUAL_ENV /env ENV PATH /env/bin:$PATH # Copy the application's requirements.txt and run pip to install all # dependencies into the virtualenv. ADD requirements.txt /app/requirements.txt RUN pip install -r /app/requirements.txt # Add the application source code. ADD . /app # Run a WSGI server to serve the application. gunicorn must be declared as # a dependency in requirements.txt. CMD gunicorn -b :$PORT main:app
