docker stats returns zero inside LxC

[dfc643]

I have a docker running inside LxC (os: alpine),
PVE version: 7.2-3
Docker version: 20.10.11

add following options for LxC container:

lxc.mount.auto: cgroup:rw
lxc.mount.auto: proc:rw
lxc.mount.auto: sys:rw
lxc.apparmor.profile: unconfined
lxc.cgroup.devices.allow: a
lxc.cap.drop:

and docker running seems be ok.

but docker stats returns zero:

i tried add kernel options:

cgroup_enable=memory swapaccount=1 systemd.unified_cgroup_hierarchy=1

but it was useless.

so does anyone know how to make docker stats work?

You're ignoring all advice and running Docker in a container? Weird things happen, that's why the advice.

where can i read about the advice? so no way to fix this? Docker runs otherwise quite well

In the manual: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#chapter_pct

Besides the manual, which based on questions here it appears nobody ever reads, there are the cries of Docker troubles right here on this forum every time a PVE upgrade comes out.
