Question

I'm tring to add sticky session on Docker Swarm and I first started to deploy the backend and the traefik containers, but the traefik dashboard isn't showing any providers

There is any problem on the stack definition?

Answer 1

In swarm mode the traefik labels must be declared on the service instead of the container, so move your labels to the deploy section.
