get Dockerfile for Google App Engine python 3 - google-app-engine

Question

I am developing a python web server in Google App Engine.
I want to debug it in VScode so I want to get the Dockerfile for the latest python 3 version in the gcr.io/google-appengine/python
Where do I get it?

Answer 1

Here is the Dockerfile you can use:
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
WORKDIR /app
# Run a WSGI server to serve the application. gunicorn must be declared as
# a dependency in requirements.txt.
ENTRYPOINT ["gunicorn", "-b", ":8080", "server:app"]
You can also look at the Github Repository

Answer 2

This is the github repo of the Python Runtime for App Engine Flex, in that repository you can find the Dockerfile and all the Scripts to create an Docker container similar than the used on App Engine Flex
# The Google App Engine base image is debian (jessie) with ca-certificates
# installed.
# Source: https://github.com/GoogleCloudPlatform/debian-docker
FROM ${OS_BASE_IMAGE}
ADD resources /resources
ADD scripts /scripts
# Install Python, pip, and C dev libraries necessary to compile the most popular
# Python libraries.
RUN /scripts/install-apt-packages.sh
# Setup locale. This prevents Python 3 IO encoding issues.
ENV LANG C.UTF-8
# Make stdout/stderr unbuffered. This prevents delay between output and cloud
# logging collection.
