Is there a guide around that teaches you to build a container from scratch with chroot, namespaces and cgroups?

  It's not a tutorial, but "Docker implemented in around 100 lines of Bash" might help: https://news.ycombinator.com/item?id=33218094 https://news.ycombinator.com/item?id=33218094

  I did one with just the chroot part: https://earthly.dev/blog/chroot/ https://earthly.dev/blog/chroot/ Liz Rice has a good talk about the cgroups and namespaces. https://www.youtube.com/watch?v=_TsSmSu57Zo https://www.youtube.com/watch?v=_TsSmSu57Zo

  This might be what you're looking for? IIRC it was written for the older cgroup (v1) sysfs interface, so you may need to cross reference it with the cgroup2 documentation https://ericchiang.github.io/post/containers-from-scratch/ https://ericchiang.github.io/post/containers-from-scratch/
