Telegraf error in container creation

[hepelayo]

Hi @gcgarner, what a great job!!

When creating the Telegraf container, an error occurs when mounting volumes:

ERROR: for telegraf Cannot start service telegraf: b'OCI runtime create failed: container_linux.go:346: starting container process caused "process_linux.go:449: container init caused \\"rootfs_linux.go:58: mounting \\\\\\"/home/pi/IOTstack/services/telegraf/telegraf.conf\\\\\\" to rootfs \\\\\\"/var/lib/docker/overlay2/391d10a5f71b6968d5917f777ed56d92e1561f8db14d4c319c3fff27aaa439d9/merged\\\\\\" at \\\\\\"/var/lib/docker/overlay2/391d10a5f71b6968d5917f777ed56d92e1561f8db14d4c319c3fff27aaa439d9/merged/etc/telegraf/telegraf.conf\\\\\\" caused \\\\\\"not a directory\\\\\\"\\"": unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type'

In my case, the error disappears if I map the directory ./services/telegraf in the volumes section of the service in docker compese.yml

The Telegraf service at docker-compose.yml would be:

telegraf:
    container_name: telegraf
    image: telegraf
    volumes:
      - ./services/telegraf:/etc/telegraf
      - ./services/telegraf/telegraf.conf:/etc/telegraf/telegraf.conf:ro
    depends_on:
      - influxdb
      - mosquitto

Thanks for your effort,

Ok, my bad.

With the above modification, the container is created but the service throws error reading the conf file.

The error is that the Telegraf config filename in the .templates/telegraf/ directory has a typo.

It should be "telegraf.conf" instead of "telgraf.conf"

This way, the docker-compose for Telegraf remains unchanged.

Thanks, in my testing I fixed it in my service folder and forgot to update the template. Will do it when I'm back home

I've pushed the changes thanks
