Hi Hernán, Please see following links: - https://github.com/pharo-contributions/Docker-Alpine - https://hub.docker.com/r/pierceng/pharovm-alpine - https://hub.docker.com/r/pierceng/pharo7-alpine - https://www.samadhiweb.com/blog/2019.07.20.alpine.pharo.minimal.html - https://www.samadhiweb.com/blog/2019.08.11.minimizing.pharo.html 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. > I am also interested in which stage you use to install packages into the > image, and why? Do you copy the contained image into docker already built? 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. > [1] http://subuser.org/news/0.3.html Interesting. I use Firejail for big programs such as Chromium. Pierce
