Hi Hern��n,

Please see following links:

The Alpine-based VM can be made smaller by removing unused/irrelevant
modules.

Image-wise, currently I am using Pharo 7 minimal, which is just under
30MB, and that forms the lower bound of the Pharo image size.

However there is also the Pharo Candle effort that aims to make really
small images, which I hope to try out soon.

For Pharo, I start with the regular or minimal image, then load my
packages.

For Docker, I first build a container image for the VM only. Using that
I build a new container image from the Pharo image and other required
files.
