Rancher Backend: Containers from different services cannot be registered to the same backend

Bug

What did you do?

I am setting up a minio cluster however I'm using multiple services to have fine grained controls over the configuration of each minio instance (volume paths). To do this I used the traefik.backend=minio label to try and put all the services in the same backend.

What did you expect to see?

A backend with all containers in every service marked with the traefik.backend=minio label.

What did you see instead?

A backend containing all containers of the last service marked with the traefik.backend=minio label. The first service is overwritten. (Caused by this line)

Output of traefik version: (What version of Traefik are you using?)

Version:      v1.3.4
Codename:     raclette
Go version:   go1.8.3
Built:        2017-07-27_03:52:53PM

What is your environment & configuration (arguments, toml, provider, platform, ...)?

Do you still have the same problem with the latest version? releases

[traefiker]

I'll close the issue due to inactivity but feel free to re-open if needed.

[chenchi2038]

@ldez

[SantoDE]

@chenchi2038 could you please try with v1.7.9?

[mpradeep1994]

I am facing the same issue, trying to setup two services from a different container as the backend for AB testing. Traefik uses only one service as a backend
