Most of your image size would come from the underlying OS (Ubuntu, Debian, Alpine), and Docker handles it pretty well by re-using OS layers when possible (push, pull, building, etc.). So what's the idea of checking your image size?
Btw, I wonder what dependencies added 1.3GB to your images. I guess some of them brought some dev dependencies that could be removed after all dependencies has been installed. Also, I usually see a line in Dockerfiles that removes apt cache. Maybe it makes sense for the Alpine package manager (apk)?

Thanks for your suggestions.
apkhas--no-cache, so it won't store any cache
