Fails with compose

This works:

```
$(docker run --rm progrium/consul cmd:run 192.168.99.101::192.168.99.100::client -d)
```

while this fails with `docker-compose up`:

```
consul:
image: progrium/consul
command: -join 192.168.99.100
ports:
- "8300:8300"
- "8301:8301"
- "8301:8301/udp"
- "8302:8302"
- "8302:8302/udp"
- "8400:8400"
- "8500:8500"
- "172.17.42.1:53:53"
- "172.17.42.1:53:53/udp"
volumes:
- "/mnt:/data"
```

With:

```
memberlist: Refuting a suspect message (from: consul)
```

Any ideas?
