How do I define the container's IP in dynamic configuration?

Traefik Traefik v2

I have this piece of code in my dynamic.yml file.

services:
  bitwarden-ui:
    loadBalancer:
      servers:
        - url: "http://172.18.0.3:80"
  bitwarden-websocket:
    loadBalancer:
      servers:
        - url: "https://172.18.0.3:3012"

I need "172.18.0.3" to be the container's actual ip address in that particular moment (bitwarden) and not a static IP like the one I set. How can I do it? Using labels I normally just specify the ports and be done with it, is there a way to it with the dynamic configuration too?

Labels example:

- traefik.http.services.bitwarden-ui.loadbalancer.server.port=80
- traefik.http.services.bitwarden-websocket.loadbalancer.server.port=3012

I think I am missing what you are trying to achieve. Why would you not just use the docker provider ?

I thought about moving the configurations away from the docker-compose file and just move everything to the Traefik dynamic configuration file because I thought it was a more organized way to configure the routers and services. If you think that is something that's gonna cause me problems, I'll just revert my configs and keep using the labels in the docker-compose file for each container. I'm kinda new to this, I thought that labels and dynamic configuration worked the same way.

I would stick with the docker provider.

You could do what you want but it wouldn't be dynamic, by setting ip addresses in you compose file.

Just for clarification, when you say docker provider that means using container labels, right? Also yea, I tried setting the IP statically for my services in the dynamic file but it's a mess, it changes all the time. Thanks for the reply.

Yes I do. I say provider because the provider needs to be enabled and docker endpoint mounted/configured etc...

Makes sense, thank you!
