Try:

FROM ubuntu:trusty

#install python
RUN apt-get install -y -qq wget python unzip
#install GAE
RUN wget https://dl.google.com/dl/cloudsdk/channels/rapid/google-cloud-sdk.zip && unzip google-cloud-sdk.zip && rm google-cloud-sdk.zip
RUN google-cloud-sdk/install.sh --usage-reporting=true --path-update=true --bash-completion=true --rc-path=/.bashrc --additional-components app-engine-python
ENV PATH /google-cloud-sdk/bin:$PATH

WORKDIR CFSA_Testapp
COPY CFSA_Testapp/ .
RUN pwd
CMD python guestbook.py
#Expose the ports
EXPOSE 8080
CMD ["dev_appserver.py", "--host=0.0.0.0", "."]

I tested it using Google's example app simply by putting it in CFSA_Testapp folder.

You can run it with docker run -it --rm -p 8080:8080 image_name.

Then you just open your browser on localhost:8080 and you are done.
