Automatic Outpost Deployment via Docker Integration prodouces invalid Traefik Labels about authentik HOT 3 OPEN

Experiencing the same issue when switching to traefik v3.

from authentik.

I'm also getting the same issue.
One inconvenient workaround (FYI, I am using Portainer to manage my docker containers/stacks), is to go to the container that was automatically created via outposts, duplicate/edit the container, click on Labels, and then edit the router rule.

e.g.
(Host(`a.domain.tld`) || Host(`b.domain.tld`)) && PathPrefix(`/outpost.goauthentik.io`)

from authentik.

Found the code in the repo that would need to be updated:

authentik/providers/proxy/controllers/docker.py:get_labels:Line:~31

    labels[f"traefik.http.routers.{traefik_name}-router.rule"] = (
        f"Host({','.join(hosts)}) && PathPrefix(`/outpost.goauthentik.io`)"
    )

Something along the lines of the following:

labels[f"traefik.http.routers.{traefik_name}-router.rule"] = (
  f"({' || '.join([f'Host(`{host}`)' for host in hosts])}) && PathPrefix(`/outpost.goauthentik.io`)"
)

from authentik.
