Downloading https://github.com/containous/traefik/blob/master/examples/consul-config.sh and the guide at https://docs.traefik.io/toml/#key-value-storage-structure running on my local Consul cluster yields nothing more than this.

Hi @jippi, your TOML file is wrong:

defaultEntryPoints = ["http"]
[entryPoints] 
[entryPoints.http] 
address = ":8080"

[web] 
address = ":8081" 

[consul] 
endpoint = "127.0.0.1:8500" 
watch = true

Also, you can launch traefik using -d to get more logs.

Your KV config seems incorrect: you must define a backend in your frontend ERRO[2016-08-02T20:17:18Z] Undefined backend '' for frontend traefik

I don't get why its asking for anything in /traefik/backends/traefik/ or /traefik/frontends/traefik/

can't find any tests with those paths, and it doesn't exist in my consul kv either

this is what I have in consul kv : https://gist.github.com/jippi/051b35676e37bf7b251ebbd6c344ff5b

@emilevauge what i have in consul is 100% (and only that) of https://github.com/containous/traefik/blob/master/examples/consul-config.sh

My bad, here is the correct TOML:

defaultEntryPoints = ["http"]
[entryPoints] 
[entryPoints.http] 
address = ":8080"

[web] 
address = ":8081" 

[consul] 
endpoint = "127.0.0.1:8500" 
watch = true 
prefix = "traefik"

Just tested, works as expected:

@emilevauge I just realized i closed the issue in a kinda-grumpy way last night.. not an excuse, but it was 23:30, and was dead tired. Layed in bad with the laptop trying to make it work for a PoC.

I'm really happy and grateful that you took your time to help me get it working that fast

Thank you! :)

Seems like the take-away here is to not include the / in your prefix. This also seems to apply when using the /traefik/alias for atomic changes. The value of the alias should not begin with a /. Perhaps the aforelinked docs should be updated?

#1352 was created when experiencing a similar issue where traefik was insisting on having a front-end called traefik when none was defined.

A PR to update the docs would be appreciated. :-)

FYI; the docs still need updating for this. If I get some time soon I'll submit one if someone else doesn't beat me to it, but I've just been scratching my head at this for about an hour!
