Request: Port ranges for entrypoints

[Kenji-K]

Here to make a request, hopefully it isn't to complicated.

I have to expose about 150 ports for a single application (traccar). The issue is, there is apparently no syntax for port ranges, so I would have to list each entrypoint individually

[entryPoints]
  [entryPoints.port1]
  address = ":5000"
  [entryPoints.port2]
  address = ":5001"
  [entryPoints.port3]
  address = ":5002"
  ...
  [entryPoints.port150]
  address = ":5150"

And from there even reference every entryPoint in the frontends. Could there instead be a way to specify a port range like so?

[entryPoints]
  [entryPoints.portRange1]
  address = ":5000-5150"

Say! Don't mean to put pressure on anyone, but could anyone evaluate how viable this is? It's not urgent by any means but it would be extremely helpful. Thanks!

calling out @emilevauge for some initial plausibility review. :)

@Kenji-K not sure to understand what you want to achieve here. Traefik will listen on 150 ports, then what?

[Kenji-K]

@emilevauge Not sure I follow. I need to direct traffic from 150 ports to a single application in a docker swarm. I've been looking for a friendly syntax to do so but haven't been able to find an answer either on Slack or Stack Overflow.

[emilevauge]

@Kenji-K do your container exposes 150 ports? Do you want to bind these 150 ports to Traefik?

[Kenji-K]

@emilevauge Pretty much. Traccar exposes 150 ports and I am deploying it in docker swarm, together with other apps, so I want to route traffic in this swarm using traefik.

Hello @Kenji-K,

Is this still an issue?

Since Sprig templating has been added in (#1891) and (#2307), you should be able to configure all of these in a friendly template loop.

Please let us know if this issue can be closed.

Thanks!

I'll check this sometime this week. Thanks.

I'm also fooling around with traccar and have the same requirement. If traefik cannot define a port range then I need to modify the traccar docker image to include SSL termination.

[ovizii]

Just to expand on the port range need for traccar, this is a snippet of how I start a traccar image:

docker run -d --restart unless-stopped --name traccar \ --hostname traccar \ --expose 8082 \ -p 5000-5150:5000-5150 \ -p 5000-5150:5000-5150/udp \ --label traefik.port=8082 \ --label traefik.frontend.rule=Host:tracking.mydomain.tld \ --label traefik.backend=tracking \ --label traefik.enable=true \ traccar/traccar:latest

traefik then knows to forward https://tracking.mydomain.tld to port 8082 but the traccar clients still communicate via HTTP only with the traccar server via Ports 5000-5150 tcp/udp

I hope this explains what exactly the original poster and myself are trying to solve.
