Taken from [this](https://r4nd0m6uy.ch/unpriviledged-containers-in-void-linux.html)
|
|
Void linux requires additional steps to set up, as Systemd is no present to automatically take care of everything.
|
|
|
|
> sudo xbps-install cgmanager dbus bridge-utils lxc
|
|
|
|
Next, startup services:
|
|
|
|
> sudo ln -s /etc/sv/dbus/ /var/service/
|
|
|
|
> sudo ln -s /etc/sv/cgmanager/ /var/service/
|
|
|
|
> sudo sv start dbus
|
|
|
|
> sudo sv start cgmanager
|
|
|
|
|
|
> sudo sv start dbus
|
|
|
|
> sudo sv start cgmanager
|
|
|
|
Maps your user account to the lxc g/u ids:
|
|
|
|
> sudo usermod --add-subuids 100000-165536 $USER
|
|
|
|
> sudo usermod --add-subgids 100000-165536 $USER
|
|
|
|
Then add a bridge interface to connect the container.
|
|
|
|
> sudo brctl addbr lxbr0
|
|
|
|
Then add an interface. I have no idea how this is done or what it means, so I tried my wifi 'wlp3s0', and that was refused. I tried the guide's one, which obviously didn't work as I didn't have the same interface as in the guide. Finally, I tried `ip addr show` and noticed other devices 'lo' and 'wwp0s20u4i6'. This gave me:
|
|
|
|
> sudo brctl addif lxbr0 wwp0s20u4i6
|
|
|
|
... which worked.
|
|
|
|
If you don't want to redo this each boot, you can make a runit service for it apparently - more research is required for this. For now, I'm just copy-pasting the guide (almost) and sticking this in ~/.config/lxc/default.conf:
|
|
|
|
`lxc.network.type = veth`
|
|
|
|
`lxc.network.link = wwp0s20u4i6`
|
|
|
|
`lxc.network.flags = up`
|
|
|
|
`lxc.network.hwaddr = 00:16:3e:BB:CC:DD`
|
|
|
|
`lxc.id_map = u 0 100000 65536`
|
|
|
|
`lxc.id_map = g 0 100000 65536`
|
|
|
|
You can now configure a different bridge each boot to connect with the lxc containers, or ....
|
|
|
|
Next, do this at *every boot* (or script it):
|
|
|
|
> sudo cgm create all $USER
|
|
|
|
> sudo cgm chown all $USER $(id -u) $(id -g)
|
|
|
|
> cgm movepid all $USER $$
|
|
|
|
|
