Sablier UI only shows when non-existent docker is configured

[bblaha]

I feel like this is a config issue, but I have now spent hours trying to find it and I can't.

Bug description I have Sablier configured and I can get it to run only, when I enter a docker into the config that is not existing. i.e. the following works

    my-sablier:
        plugin:
            sablier:
                dynamic:
                    displayName: My Title
                    refreshFrequency: 5s
                    showDetails: "true"
                    theme: ghost
                group: default
                names: PasswordPusherEphemeral,whoami,nginx
                sablierUrl: http://sablier:10000
                sessionDuration: 1m

and I can call sablier.example.com or whoami.example.com. Here is the thing, however: I do not have a container called nginx. And it throws that error. When I remove nginx (or any other non-existent container for that matter, such as follows...

    my-sablier:
        plugin:
            sablier:
                dynamic:
                    displayName: My Title
                    refreshFrequency: 5s
                    showDetails: "true"
                    theme: ghost
                group: default
                names: PasswordPusherEphemeral,whoami
                sablierUrl: http://sablier:10000
                sessionDuration: 1m

I cannot reach the UI anymore, neither via sablier.example.com nor via whoami.example.com. Instead I get a 404 page not found.

Also, when I DO add the non-existent container, ALL containers that Sablier is assigned to as middleware only show the Sablier UI, they never forward and even reloading does not get me to the actual service.

I am running 1.4.0-beta3 on both the container and the traefik plugin.

Hi @bblaha !

Can you please share your whole configuration ?

Where I could see the Traefik configuration, the sablier container and the services you try to route.

You have to understand that you should not use names and group together.

These are two different method to tell sablier which set of containers to start and stop.

Sure, here is my traefik.yaml (static config file)

And here is my docker run command (on Unraid, which has some specifics, but generally is the same)

docker run -d --name='sablier' --net='dockernet' -e TZ="Europe/Berlin" -e HOST_OS="Unraid" -e HOST_HOSTNAME="Tower" -e HOST_CONTAINERNAME="sablier" -l net.unraid.docker.managed=dockerman -l 'traefik.enable'='true' -v '/mnt/user/appdata/sablier/sablier.yaml':'/etc/sablier/sablier.yaml':'rw' -v '/var/run/docker.sock':'/var/run/docker.sock':'rw' 'acouvreur/sablier:beta'

I think that should be everything

I have tried setting everything up again from scratch, but I am still ending up with the same problem, so I would assume I have a fundamental misunderstanding of some setting or it is a bug
