Telegraf Docker SmartCTL not working

Telegraf
1

Hi,

i have a problem to get SmartCTL working in Telegraf in Docker.

What i have done:

Edited sudoers File /etc/sudoers:

# For smartctl add the following lines:
Cmnd_Alias SMARTCTL = /usr/sbin/smartctl
telegraf ALL=(ALL) NOPASSWD: SMARTCTL
Defaults!SMARTCTL !logfile, !syslog, !pam_session

Edited telegraf.conf:

[[inputs.smart]]
path_smartctl = "/usr/sbin/smartctl" 
use_sudo = true
attributes = true

In Docker i added this docker-compose.yml:

version: "3.0"
name: "telegraf"
services:
    telegraf:
        image: telegraf:latest
        container_name: telegraf
        network_mode: host
        privileged: true #for smartctl
        environment:
          - TZ=Europe/Berlin
          - HOST_ETC=/hostfs/etc
          - HOST_PROC=/hostfs/proc
          - HOST_SYS=/hostfs/sys
          - HOST_USR=/hostfs/usr
          - HOST_MOUNT_PREFIX=/hostfs
        volumes:
            - /var/run/docker.sock:/var/run/docker.sock
            - /home/docker/telegraf/telegraf.conf:/etc/telegraf/telegraf.conf:ro
            - /:/hostfs:ro
            - /run/udev:/run/udev:ro
            - /usr/sbin:/usr/sbin:ro            
        logging:
          driver: json-file   
        restart: unless-stopped

I get this Error from the Telegraf Logs:


2025-07-01T12:27:49Z W! [inputs.smart] nvme not found: verify that nvme is installed and it is in your PATH (or specified in config) to gather vendor specific attributes: provided path does not exist: []
2025-07-01T12:28:00Z E! [inputs.smart] Error in plugin: failed to run command '/usr/sbin/smartctl [--scan]': exec: "sudo": executable file not found in $PATH -

Ideas how to get smartctl working ?

It cant work because Telegraf has no sudo and no smartmontools installed inside the Container.
Its a shame

Use this instead the official Telegraf Docker:

https://hub.docker.com/r/golift/telegraf

Then it works fine
