I guess the question is in which way dangerous?
It might lead for crash for sure, but is that crash controlled? If it is, then it is just a crash. Stability vs. minimal attack surface
But I agree, this is just bandaid for lazy bois. Better use Bazel etc. for distroless builds
This is dangerous in that it strips assets, resources, and files from your app without understanding how they are used.
If you forget a critical code path when you build using Docker-Slim, and a resource file is not used, that resource will be stripped. The feature which depends on it will be broken in production.
i would disagree i use em in production apps, i configured it and it works if you do it blindly it happens that sometimes things break but if you configure it, it will work
There is no guarantee that a blind code shaker will leave in everything important while stripping out everything that isn't. How could it possibly know?
If Docker-Slim is working for you in production apps, you are either getting lucky or your app is trivial enough to lack unseen code paths.
