Confusing message when setting up the limits in YAML file

[kkebb]

Hello again.

So I was setting up a service in my YAML file as follows:

  test:
    image: busybox
    instances:
      bb1:
        ship: boot2docker
        limits:
          memory: 512m
          swap: 256m
          cpu: 1
        command: /bin/sh -c "while true; do echo hello world; sleep 1; done"

and when I started up the service, this is the stack that I see:

#  INSTANCE                                 SERVICE              SHIP                                     CONTAINER                  STATUS    
  1. bb1                                      test                 boot2docker                              failed to start container! failed!

Your efforts are much appreciated.
