Telegraf: Docker Plugin not finding Docker socket

[hrzbrg]

Hi

after I updated a testing host from 0.11.1 to 0.12.1 the Docker plugin stopped working. The log shows:

Error in input [docker]: Cannot connect to the Docker daemon. Is the docker daemon running on this host?

But when I run telegraf -config /etc/telegraf/telegraf.conf -input-filter docker -test it outputs the values to stdout.

I also tried the most recent nightly, which produces the same error.

docker info is:

Containers: 5
 Running: 3
 Paused: 0
 Stopped: 2
Images: 69
Server Version: 1.10.3
Storage Driver: aufs
 Root Dir: /var/lib/docker/aufs
 Backing Filesystem: extfs
 Dirs: 182

Execution Driver: native-0.2
Logging Driver: json-file

Operating System: Ubuntu 14.04.4 LTS

Looks like permissions problem.

try running as the telegraf user: sudo -u telegraf telegraf -config /etc/telegraf/telegraf.conf -input-filter docker -test

[hrzbrg]

okay, sudo usermod -aG docker telegraf solves it

thanks for posting the solution @hrzbrg
