No docker data

[zangaby]

Hello, I just deployed your template and all seems fine except the docker data. I am using Client: Docker Engine - Community Version: 24.0.2 on Linux pi 6.1.21-v7l+ #1642 SMP Mon Apr 3 17:22:30 BST 2023 armv7l GNU/Linux

The only logs from the cadvisor logs are: W0613 19:39:05.043316 1 sysinfo.go:203] Nodes topology is not available, providing CPU topology W0613 19:39:05.046549 1 machine.go:65] Cannot read vendor id correctly, set empty.

This issue has been inactive for some time. Please let me know if it's still relevant and need attention or I will close it.

[zangaby]

Yes, the issue is still relevant. I assume it is related to the fact that I run docker rootless.

You could try adding additional capabilities to the cAdvisor container to see if that resolves the issue.

  cadvisor:
    container_name: monitoring-cadvisor
    image: gcr.io/cadvisor/cadvisor:v0.47.1
    hostname: rpi-cadvisor
    restart: unless-stopped
    privileged: true
    cap_add:
      - SYS_PTRACE
      - SYS_ADMIN
    networks:
      - internal
    expose:
      - 8080
    devices:
      - /dev/kmsg
    volumes:
      - /:/rootfs:ro
      - /run/user/$(id -u)/docker.sock:/var/run/docker.sock:ro
      - /sys:/sys:ro
      - ~/.local/share/docker/:/var/lib/docker:ro
      - /dev/disk/:/dev/disk:ro
      - /etc/machine-id:/etc/machine-id:ro

Thanks, unfortunately I ran into this error:

docker-compose up --force-recreate -d ERROR: Invalid interpolation format for "volumes" option in service "cadvisor": "/run/user/$(id -u)/docker.sock:/var/run/docker.sock:ro"

[oijkn]

The error you're encountering is due to the use of shell interpolation ($(id -u)) in your Docker Compose file, which is not directly supported. You can work around this by using an environment variable. Modify your Docker Compose file as follows:

volumes:
  - /run/user/${UID}/docker.sock:/var/run/docker.sock:ro

Then set the UID environment variable before running docker-compose up:

export UID=$(id -u)
docker-compose up --force-recreate -d

[zangaby]

As a regular user it seems not to work. export UID=$(id -u) -bash: UID: readonly variable I tried adding the actual UID on that line and now most of the data on the dashboard is populated, only I/O RX/TX FS is missing.

I'm glad I've helped you, keep looking in this direction for the rest :)

Thanks a lot for your help !
