marathon traefik.backend=foo seems broken

[kbroughton]

If i add this to labels in a marathon .json job

traefik.backend=k4b4-mantl-worker-001.example.com

level=error msg="Error loading new configuration, aborted Undefined backend: backendk4b4-mantl-worker-001.example.com"

either the error message is formatted wrong, or the value is concatenated badly.

If it is just badly formatted error, how do I make k4b4-mantl-worker-001.example.com defined when k4b4-mantl-worker-001.node.consul is the default value?

traefik.backend cannot ne used to change the backend url ;)
It seems more logical to change your DNS settings here, to match your needs.
Can I close this one?

[kbroughton]

Yes.
However, i would suggest changing the docs to be more clear. foo suggests it can be any old thing. If i understand right, it should be 1 or 2 if there are multiple backends.

https://docs.traefik.io/toml/
traefik.backend=foo: assign the application to foo backend

If you explain how to submit PRs for docs I can contribute.
However, i don't see these docs at
https://github.com/containous/traefik/tree/master/docs
