[FR] For slim images remove docs, mans and other irrelevant files
HectorB-2020 opened this issue · 2 comments
Hello! I was surprised to find plenty of files under /usr/share/man and /usr/share/doc/
In my view Debian-based images lack a few lines in its configs line below:
path-exclude=/usr/share/man/*
path-exclude=/usr/share/doc/*Similar configuration exists for CentOS as well.
So I'll appreciate of you consider leaving all docs/mans/infos aside for the sake of image slimness.
Hello.
Do you indeed use a slim image? Slim images contain slim in their tags:
https://hub.docker.com/r/bellsoft/liberica-runtime-container
and they do not contain docs or mans.
For example:

@kholmanskikh, thanks for pointing me to slim images with glibc. 👍
We're afraid of using Alpine-based images due to their problems with DNS resolution in k8s under certain circumstances, so we ruled to switching to Debian-based images, hence my initial question.
So I wonder if you tested these images with glibc for various DNS cases.
