Yes, I know so much of Alpine’s lightweightness comes from not using glibc.
But still, the other options I see are far from being slimmed down. Debian, Ubuntu server, CentOS… They all could use some cuts.
What’s the most slimmed down non-desktop distro that still has a glibc base? I honestly don’t care if it has its own package manager (build tool handles this for me). Just wanna use it in containers for running server apps.
I assume with “non-desktop” you mean “container” and not, say, server or embedded? In that case Wolfi is a candidate.
What runtime do you need? If it’s Node.js, the “slim” Docker images are lightweight and based on Debian. (for example
node:lts-slim)250mb is a curios interpretation of “lightweight”
Standard
nodeimages are around 1 GB.node:lts-alpineis about 176 MB. So it’s fairly close toalpinein this case.Sure, but it you consider that 166MB of that is for the node part alone, the “slim” image ships 80MB of stuff to basically do nothing
It would be interesting to see what the difference is. The
slimimage doesn’t even haveviinstalled, although it does havebash. And of course,git, etc. are not present. Much of the difference could be the size difference between musl and libc, and the size difference betweenapkandaptmetadata.I don’t think OP is going to find a non-musl distro as small as Alpine. These stripped-down Debians are a lot bigger, but among the smallest non-Alpine that you’ll find.
The Wolfi based chainguard images for node are glibc based and come in at 111mb, so its definitely possible.
May be worth looking at distroless containers.
You can completely customize Gentoo Linux to be what you want it to be and slim it down to what you need.
My experience with gentoo docker images is that they’re pretty big. I’m not sure why. Maybe the build system or the python deps make it big. I tried squashing the image layers and it was still big, so it isn’t that.
