HN discussionI find plain Linux namespaces as sufficient for many things, for example: unshare --map-root-user chroot ~/rootfs /bin/sh Sure, it might not be able to clone the rootfs for you, but you don't need snapd to install it and it comes as part of util-linux, essentially being part of almost all Linux systems. ( https://ilearnedhowto.wordpress.com/tag/unshare/ is a nice introduction.) Edit: https://ericchiang.github.io/pos…

HN discussionThis 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/

HN discussionIf this struck your interest, but you want more nitty gritty examples and details, you may find the following article interesting: https://ericchiang.github.io/post/containers-from-scratch/ If I'm remembering correctly from when I ran through the instructions at home, it was written for the original cgroup sysfs interface rather than the more modern cgroup2 [0]. You can figure out which you're running with > mount |…

HN discussionStart with namespaces and cgroups. Once you realize that docker is basically a management interface over those, everything will click. I’m trying to find a really good blog from years ago but having trouble. This looks good though: https://ericchiang.github.io/post/containers-from-scratch/

HN discussion> How does this work? Essentially, like this: https://ericchiang.github.io/post/containers-from-scratch/ https://earthly.dev/blog/chroot/ > The way Docker Desktop (and podman.io) implement "containers on macOS" is a bit of a cop-out It's not, it's a requirement for running Linux containers: https://news.ycombinator.com/item?id=37656401 DfM is more like running the CLI locally to a remote Linux machine, and all it do…
