[SOLVED] Error while creating zigbee2mqtt on LXC

[Bison]

Hello,

I'm using Proxmox 8.2.8 (just updating to have USB passthourgh).

I try to create a new container for zigbee2mqtt. I created a LXC in Proxmox and use other containers with success since months.




I tried to create this using a Stacks with Portainer but i got the same error with docker.

From host :

root@pve2yp:~# ls -l /dev/serial/by-id
total 0
lrwxrwxrwx 1 root root 13 Nov 16 19:39 usb-1a86_USB_Serial-if00-port0 -> ../../ttyUSB0

From CT "docker" i can see the mapping :

root@docker:~# ls -l /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0
crw-rw---- 1 root root 188, 0 Nov 16 18:41 /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0

I run this :

docker run \
   --name zigbee2mqtt \
   --restart=unless-stopped \
   --device=/dev/serial/by-id/usb-1a86_USB_Serial-if00-port0:/dev/ttyUSB0 \
   -p 8080:8080 \
   -v /srv/docker/zigbee2mqtt/data:/app/data \
   -v /run/udev:/run/udev:ro \
   -e TZ=Europe/Paris \
   koenkk/zigbee2mqtt

And got this error :

docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error creating device nodes: mount /dev/ttyUSB0:/var/lib/docker/overlay2/57907ebd0d70e18055abb8b88420afde7dcd73cbcc0c4c8c933e26e392a3324e/merged/dev/ttyUSB0 (via /proc/self/fd/6), flags: 0x1000: no such file or directory: unknown.
ERRO[0000] error waiting for container:

Could you help ? I tried many things since hours but nothing works.

Please post the results of

ls -lL /dev/serial/by-id

from the host.

What I tought. You may run into a permission problem here. You LX(C) container is probably unpriviledged, so that you will not have access to the file in LXC and therefore also not in your docker container.

My setup is like this:

• LXC docker-compose-stack
  
  app:
  image: koenkk/zigbee2mqtt
  hostname: zigbee2mqtt
  volumes:
  - data:/app/data
  - /run/udev:/run/udev:ro
  devices:
  - /dev/ttyUSB0:/dev/ttyUSB0
  
  and this file
  
  $ ls -l /dev/ttyUSB0
  crw-rw-rw- 1 nobody root 188, 0 Nov 17 10:22 /dev/ttyUSB0
  
  
• PVE / hypervisor setup
  
  root@proxmox /etc/pve > cat /etc/udev/rules.d/99-usb-serial.rules

  The group is also important, this is root in the unpriviledged container.

Oh it works with the Stacks i want to use, thank you !

As i allready tried like this i suspect what you said ...

GROUP="100000"

is very important because i didn't try with this option

I will now try in real condition with my other Zigbee key on ttyACM0 but i think it will be good.

Come soon to update and close.
