Google Cloud Platform - Python Runtime Docker Image
This repository contains the source for the
docker base image. This image can be used as the base image
for running applications on
Google App Engine Flexible,
Google Kubernetes Engine, or any
other Docker host.
This image is based on Ubuntu Xenial 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
runtime: python env: flex entrypoint: gunicorn -b :$PORT main:app runtime_config: # You can also specify 2 for Python 2.7 python_version: 3
If you have an existing App Engine application using this runtime and want to
customize it, you can use the
to create a custom runtime:
gcloud beta app gen-config --custom
You can then modify the
.dockerignore as needed for you
Kubernetes Engine & other Docker hosts.
For other docker hosts, you'll need to create a
Dockerfile based on this image
that copies your application code, installs dependencies, and declares an
command or entrypoint. For example:
FROM gcr.io/google-appengine/python # Create a virtualenv for dependencies. This isolates these packages from # system-level packages. # Use -p python3 or -p python3.7 to select python version. Default is version 2. RUN virtualenv /env # Setting these environment variables are the same as running # source /env/bin/activate. ENV VIRTUAL_ENV /env ENV PATH /env/bin:$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
