Portainer Stack vs docker-compose volume creation

Question

i'm trying to run my docker-compose file in Portainer

https://github.com/youcann/mqttTelegrafInfluxGrafana-dockerCompose

However when creating the stack i get the error:

level=info msg="ERROR: for telegraf  Cannot start service telegraf: OCI runtime create failed: container_linux.go:367: starting container process caused: process_linux.go:495: container init caused: rootfs_linux.go:60: mounting \"/data/compose/17/telegraf/telegraf.conf\" to rootfs at \"/var/lib/docker/btrfs/subvolumes/ef51fdc129afe44be30016da700c8fe1a0b1267971c48e0e521e1e90de9ce1d3/etc/telegraf/telegraf.conf\" caused: not a directory: unknown: Are you trying to mount a directory onto a file (or vice-versa)?

So it looks like there is a problem with the volumes. How can i modify the docker-compose.ymlto fix this?

Answer 1

use an absolute path instead of a relative path so for example instead of ./telegraf/telegraf.conf:/etc/telegraf/telegraf.conf:ro use /var/lib/telegraf/telegraf.conf:/etc/telegraf/telegraf.conf:ro
