If you build containers, you should be looking into Docker Slim (lemmy.fancywhale.ca)

As the title says. I build containers for my platforms/clients/myself-selfhosted@home and you would not believe how much smaller you can get your images. Here's an example when slimming one of my images:

cmd=build info=results status='MINIFIED' by='18.97X' size.original='1.0 GB' size.optimized='55 MB'

That's a Python app that I didn't have to do multi-staged build with docker because of the Slim command. And it's a working version of that app that I'm using today.

Same for one of my flutter apps that I thought it was as small as it could be:

cmd=build info=results status='MINIFIED' by='1.98X' size.original='66 MB' size.optimized='33 MB'

TLDR: slim your container images!! https://github.com/slimtoolkit/slim

Great write up! That's everything exactly right. It's mostly useful to try and reduce the time it takes to pull images to run them. And also reduce the footprint of storing those in your registries.
