Fails with compose

[ronag]

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?
