Panics parsing volume config

[spullara]

I think it maybe because they are at the top level

version: '2'
volumes:
  dynamo_db:
  redis:

then defined later in particular services:

    volumes:
     - dynamo_db:/var/dynamodb_local

exception:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x90b6d7]

Hi @spullara,
Thank you for reporting it. It looks like this is issue in libcompose - docker/libcompose#430 . Should be fixed in next release.

[cdrage]

@kadel Perhaps we can update the vendoring for Kompose ? 👍

[kadel]

yep, lets update vendored libcopmose and test it. So we can get this to next release
