Custom label migrate to dynamic configuration

Traefik Traefik v3 (latest)

As described here, i use a label - "dev.gero.expose-internally=true" to tell one of my two traefik instances to serve this container.

traefik.yaml

providers:
  docker:
    endpoint: "unix:///var/run/docker.sock"
    exposedByDefault: false
    constraints: "Label(`dev.gero.expose-externally`,`true`)"

Now i wanna use Sablier for some of my container (Scale to Zero).

Unfortunately to use Sablier, i have to switch to dynamic configuration files, for these container.

dynamic-config.yaml

http:
  services:
    whoami-sablier-service:
      loadBalancer:
        servers:
          - url: "http://whoami:80" # http://xxx:yy xxx is the container name and yy port inside the container
          #- port: 80

  middlewares:
    sablier-whoami:
      plugin:
        sablier:
          sablierUrl: http://sablier:10000
          sessionDuration: 15m
          # names here will be reference to the docker container name
          names: whoami
          dynamic:
            displayName: Whoami
            refreshFrequency: 5s
            showDetails: "true"
            theme: shuffle

  routers:
    whoami-sablier-router:
      rule: "Host(`whoami.mydomain.de`)"
      service: whoami-sablier-service # reference to the services name that defined above
      entryPoints:
        - "websecure"
      middlewares:
        - sablier-whoami@file
      tls:
        certResolver: myresolver

dev:
  gero:
    expose-internally: "true"

wud:
  watch: "true"
  include: "v\d+\.\d+\.\d+$$"

I also use WUD (What’s up docker). The labels are

      - wud.watch=true
      - wud.tag.include=v\d+\.\d+\.\d+$$

Can you point me in the direction to migrate the labels to the dynamic configuration file?
Labels and dynamic configuration files at the same time are not possible right?

I would says those labels are Docker service/container labels, therefore they should stay in a Docker compose file.

So i can use dynamic configuration file and labels simultaneously?

Yes, you can use providers.file and providers.docker in parallel.

And plain Docker label definition needs to be in compose file anyway.
