Updated health checks failing on GAE with custom runtime

[Mike Hardy]

Hi There, we're having problems getting our app to function correctly using a custom runtime and updated health checks. We're using the custom runtime to add tests + migrations to our deployment. Below are our Dockerfile, urls.py, and app.yaml. I'm also including a snapshot of the logs Where are we going wrong? Any suggestions? Note: if we use the standard python runtime with legacy checks, the app works fine, but no tests/migrations.

Dockerfile

FROM gcr.io/google-appengine/python

# Use python 3 version of GAE base image

LABEL python_version python3.5

RUN virtualenv --no-download /env -p python3.5

ENV VIRTUAL_ENV /env

ENV PATH /env/bin:$PATH

# Install all dependencies in requirements.txt

ADD requirements.txt /app/requirements.txt

RUN pip install -r /app/requirements.txt

# Add the application source code.

ADD . /app

# Run staging migrations then tests. Then run the gunicorn server

WORKDIR /app

EXPOSE 8080

CMD python manage.py migrate --settings app.settings.staging && \

    gunicorn -b :8080 app.wsgi
