Microservice Patterns and Best Practices

Configuring the container

With config.yaml and requirements.txt ready, let's modify Dockerfile. While the execution of the requirements.txt file is all the same as before, the difference is due to ENTRYPOINT and CMD, because now they will use the Nameko framework. See also that, in CMD, we are passing the config.yaml file that we just created:

FROM python:3.6.1 
COPY . /app 
WORKDIR /app 
RUN pip install -r requirements.txt 
ENTRYPOINT ["nameko"] 
CMD ["run", "--config",  "config.yaml", "service"] 
EXPOSE 8000
