[UX] - Using smaller base image in Dockerfiles to reduce overall size of refinery #145
Description
What would you improve?
The images of the Python services are all based on a python base image provided by dockerhub. Multiple versions of this base image exist which all differ in the amount of preinstalled packages and in size. At the moment the services are based on the largest base image but not all services need all the preinstalled images. Switching to a smaller base image if possible would reduce the overall size of refinery a lot.
