Docker-traefik-prometheus-grafana stack doesnt create traefik container upon service deploy

Traefik Traefik v2
, , , , ,
1

Hey everyone,

I am trying to run a traefik-grafana-prometheus stack in my docker swarm node but for some reason my error logs are empty. I was able to grep and tail the docker service logs on my Ubuntu 20.04LTS and able to get some info.
I followed instructions from here for installing:


Any help would be greatly appreciated. :slight_smile:

I was able to get a seperate traefik instance working successfully and I was wondering what is the difference between the two that makes the initial YAML (config shown here) work and why the one above (docker-traefik-prometheus) doesn't work and is difficult to diagnose.
