edit 2 Addendum

OK, big thanks to @oakcroissant@feddit.org for bringing this to attention here: https://europe.pub/post/390395/686949

that gets to the root (har har) of my confusion here. am i missing the point of MicroOS, or is it the devs who are wrong? 😆

their INTENTION with MicroOS is for us to just use root, which is contrary to how i’ve lived Linux basically forever.

Podmans rootless containers are AWESOME on Aeon, where you’re using it interactively and already have none root users… but that would just be adding unnecessary complications to MicroOS

MicroOS is designed to use with root, and there is no need to create a non root user for anything.

IF there was a need to create a non root user then the installer would create a non-root user

which is exactly what was tripping me up. why weren’t they facilitating rootless activity, and thus making me jump through hoops to get there.

answer: because it’s not needed, and not the intention.

MicroOS: run as root.


edit Answer

yes, MicroOS only generates a root user at install.

if you want to do rootless containers, you will need to create new, non-root users after.

useradd will NOT generate entries for subuid/subgid by default for the new SYSTEM users.

if the system user already exists, you will need to add them manually:

usermod --add-subuids 100000-165535 <yourusername>
usermod --add-subgids 100000-165535 <yourusername>

otherwise, you must use the -F flag with useradd to generate subids for new system users.

thanks all!


hey all! i need a little help here.

i’m just starting to get into self-hosting, and have chosen MicroOS and podman as my environment and tool.

would someone be able to clarify something for me?

I have a MicroOS install for containers, and it seems to only come with a root user. so if i use podman, won’t all my pods be rootful?

i try to make a new non-root user, but podman just keeps complaining about privileges when i run it under that user.

so how is this intended to work exactly?

thanks for any help!

    Tldr:

    Rootful podman with podman run --userns=auto is more secure than one rootless host user running many pods, because those pods could (theoretically) attack each other.
    though you still have the possibility of an exploit in the image pull

    Rootless podman running one pod (as in service including database and so on) per host user with different subuid Ranges is the most secure, but you have to actually set that up which can be a lot of work depending on distribution.
