i'll be happy to answer any questions about the tool (i'm the main author) :-)

This looks pretty amazing, thanks for sharing. I've just been playing with this on a couple containers. The first went from 197MB to 71.5MB - not bad! I did some testing and it didn't work without including a few extra pieces but pretty painless.

The second container went from 176MB to 4.7MB!! I've not really tested that so there's a pretty good chance things aren't going to work too well in practice (but we'll see).

If it all continues as well as it's started then we'll definitely be using it.

Do you mind sharing a bit of information about your container images? What's the app language for both? What kind of application is it? How do you init your apps in the containers? docker-slim is definitely not perfect and there's lots of room for improvement. Can you ping me offline (on github/gitter, twitter or email, my email is kcq.public@gmail.com)?

Please add a better description of what the tools does, like "Docker-slim removes all files which you container doesn't touch when running"

Considering CI/CD attacks these days I spend a while scanning if this tool was some kind of joke trying to show that developers download anything from the Internet.

PS: Thanks for this :)

Thank you for the your feedback! It's very important for a tool like this to be clear and transparent about what it's doing. The docs definitely need to be improved. It's already a lot for some info to be lost and not enough, at the same time, in other areas.

By the way, if you don't feel comfortable with the minification functionality you can still use docker-slim as a Docker image inspection and profiling tool (take a look at the report files it generates). Additional package level reporting is on the todo list. Image and Dockerfile linting functionality is coming soon too.
