google app engine - Multiple services with different dockerfiles on GAE Flexible

Question

I'm using Google AppEngine Flexible with python environment. Right now I have two services: default and worker that share the same codebase, configured by app.yaml and worker.yaml. Now I need to install native C++ library, so I had to switch to Custom runtime and added Dockerfile.

Here is the Dockerfile generated by gcloud beta app gen-config --custom command

FROM gcr.io/google-appengine/python
LABEL python_version=python3.6

RUN virtualenv --no-download /env -p python3.6

# Set virtualenv environment variables. This is equivalent to running
# source /env/bin/activate
ENV VIRTUAL_ENV /env
ENV PATH /env/bin:$PATH
ADD requirements.txt /app/
RUN pip install -r requirements.txt
ADD . /app/
CMD exec gunicorn --workers=3 --threads=3 --bind=:$PORT aces.wsgi

Previously my app.yaml and worker.yaml each had it's own entrypoint: config that specified the command needed to be run to start the service.

So, my question is how can I use two different commands to start the services?

EDIT 1

So far I was able to solve this by rewriting CMD line in dockerfile for each deploy of each service. However, I'm not quite satisfied with this solution.

gcloud app deploy command has --image-url flag that allows to set image url from GCR. I haven't researched that yet, but it seems that I can just upload images to GCR and use the urls since don't change that often
