Cadvisor fails on Raspberry PiOS Bullseye - cgroup v2 error

[bdollerup]

Hi there,

I'm trying to get the cadvisor container to work on my RPI 4 with Bullseye Lite. And I'm seeing the below in the container log:

Here's what mount says:

mount | grep cgroup
cgroup2 on /sys/fs/cgroup type cgroup2 (rw,nosuid,nodev,noexec,relatime)

Here's my docker-compose file:

version: "3.8"
services:
  cadvisor:
    container_name: cadvisor
    devices:
      - /dev/kmsg
    expose:
      - 8080
    hostname: proxydns-02
    image: zcube/cadvisor:latest
    ipc: shareable
    privileged: true
    restart: unless-stopped
    security_opt:
      - label=disable
    volumes:
      - /:/rootfs:ro
      - /var/run:/var/run:ro
      - /sys:/sys:ro
      - /var/lib/docker/:/var/lib/docker:ro
      - /dev/disk/:/dev/disk:ro

I've tried adding the cgroup_enable=memory cgroup_memory=1 option to the /boot/cmdline.txt file, but I'm getting the above error no matter what I do.

Any suggestions are greatly appreciated.

@bdollerup have you tried the suggestions that were made in the other thread? While cadvisor may complain about warning and error messages like the following:

I have not seen issues with the grafana reporting the data correctly. Give the suggestions in that thread a try to see if that helps.
