CONSUL_BIND_INTERFACE not working?

I am trying to set my bind interface through CONSUL_BIND_INTERFACE and it is pulling the correct IP for the interface but it is still giving me an error:

```
[fakeuser@fakeserver fakedir]$ docker run -it --rm --net=host -e "CONSUL_BIND_INTERFACE=eth1" consul consul agent -client=0.0.0.0 -ui -retry-join=server1.us.local -retry-join=server2.us.local -retry-join=server3.us.local -data-dir=/tmp/consul
==> Found address '100.73.14.171' for interface 'eth1', setting bind option...
==> Starting Consul agent...
==> Error starting agent: Failed to get advertise address: Multiple private IPs found. Please configure one.
```

When I run it and fill in the bind address manually it works:

```
[fakeuser@fakeserver fakedir]$ docker run -it --rm --net=host consul consul agent -ui -client=0.0.0.0 -bind=100.73.14.171 retry-join=server1.us.local -retry-join=server2.us.local -retry-join=server3.us.local -data-dir=/tmp/consul
==> Starting Consul agent...

I'm not sure why its not working as its getting the right bind address to pass to -bind.
