Reduce the size of Ubuntu Docker images
Raw
gistfile1.txt
When you build from Ubuntu, apt-get update increases the size by about 600GB.
Instead, don't install the recommended updates, just what you need:
In your docker file:
RUN apt-get update && apt-get install --no-install-recommends --yes python3
