Anaconda Dockerimages

I am playing currently with Docker. Given the following simple Dockerfile:

# Set the base image to Ubuntu
FROM continuumio/miniconda3

# File Author / Maintainer
MAINTAINER Thomas Schmelzer

ADD . /pybank

WORKDIR /pybank

# build the environment
RUN conda install -y --file production.txt && conda clean --all --yes && nosetests

The resulting image is like 1.0 GB. In production.txt are pandas and nose. The folder for the pybank project is 230 KB within the running image. I am reading a lot about hacks trying to squezze the resulting images. Any ideas?

Here's the output of docker history:

This solution works if you don't care about the image history:

Create a container from the image

docker run --name my_container -it my_image:my_tag my_command

Export the container

docker export my_container > my_container.tar.gz

Import the container as an image:

cat my_container.tar.gz | docker import - my_small_image:my_tag

Check the new image entry

docker images
