Not Working about docktor

[The-Inamati]

Ok. Won't fit my use case then. I have no need to publish ports with Traefik. Best of luck to you anyway. Hope people use it.

Hey, thanks for notice! I think the issue was here:
port := strconv.FormatUint(uint64(container.Ports[1].PublicPort), 10)
Firstly, the code was checking if the container array length was > 1, which meant it never checked if only one container was passed (this was really stupid of me). Also, Index 1 of container.Ports was causing the error too on my end - changing this to index 0 fixed it. Let me know if this worked for you.
Edit: I just pushed the changes to master, so you should be good to see if this fixed on your end.

Nope. Still not working. This time it listed everything I have running and then

panic: runtime error: index out of range [0] with length 0

Is the container you're running on a port? That function restarts the container on it's port so if it's not then it won't work - I'll also make a quick check of this. Try running it with nginx like the example and see if it works.

[The-Inamati]

What do you mean? I ran it against a service like the following:

drop:
    image: ghcr.io/linuxserver/snapdrop
    container_name: drop
    <<: *tiny
    depends_on:
      - rsshub
    networks:
      - traefik
    environment:
      - PUID=$PUID
      - PGID=$PGID
      - TZ=$TZ
    volumes:
      - drop:/config
    labels:
      - "traefik.enable=true"
      ## HTTP Routers
      - "traefik.http.routers.drop.entrypoints=https"
      - "traefik.http.routers.drop.rule=Host(`$DROP_SUBDOMAIN.$DOMAINNAME1`)"
      - "traefik.http.routers.drop.tls=true"
      ## HTTP Services
      - "traefik.http.routers.drop.service=drop"
      - "traefik.http.services.drop.loadbalancer.server.port=80"
      - "traefik.http.routers.drop.middlewares=chain-no-auth@file"

Basically the issue is that the docker api can't find the port exposed in that container - this is likely to do with some part of the configuration of your container. I'm guessing that's a compose file but I don't see a port exposed on it. Again, try running it on another container that's using an existing port on your system.
PS: I edited the code so it won't work if the docker api can't find the port - it's just not going to do anything instead.

[The-Inamati]

It does expose a port. It just doesn't publish it.

[nishgowda]

That might be the problem then try publishing the port or try on another container that has published its port.

[The-Inamati]

What is the command you use to get the port the container is using?

[nishgowda]

The full code is in the health check part of the lib directory. Also, by looking at the screen shot it doesn't look like it's published a port on your local machine (if that's all docker ps says that is). If you run your container with the -p command and map it to a port it should work.
