It would be great to get a better diagnose than "not working". What’s not working? Are all containers up? Did you check Traefik dashboard?

Usually you would just expose `ports` on Traefik, not on the other services/containers. Otherwise Traefik security middlewares can be circumvented. Traefik should forward requests internally over Docker network, in which all ports are reachable.

Portainer should work with internal port 9000, check [this post](https://community.traefik.io/t/portainer-behind-traefik-bad-certificate-insecureskipverify-true-does-not-kick-in/21848/2) from this week.

Did you use `docker stack deploy`? Compare to working [simple Traefik Swarm example](https://github.com/bluepuma77/traefik-best-practice/tree/main/docker-swarm-traefik).
