For https://edu.oggm.org (repo), we need an environment with a lot of packages from the python-GIS stack. Our docker image was 4.3Gb large, so I spent some time moving to a pure pip install, reducing the image size from 4.3Gb to 3.3Gb.
However, the resulting image is still very large because conda is still installed per default (I suppose).
As per https://mybinder.readthedocs.io/en/latest/faq.html#what-factors-influence-how-long-it-takes-a-binder-session-to-start , I understand that reducing the image size is not the biggest priority, but wouldn’t there still be a gain if we managed to get down to 1Gb?
This would only be possible by ditching conda altogether, which is something repo2docker may not be able to do anyway: I just wanted to ask here if this would be a possibility, and especially if reducing the image size is really worth the trouble in the first place.
