Permission denied on docker-compose up

I've tried to run graylog with docker-compose using the example found in readme.md and got this:

$ docker-compose up
WARNING: Some services (elasticsearch) use the 'deploy' key, which will be ignored. Compose does not support 'deploy' configuration - use `docker stack deploy` to deploy to a swarm.

Mongo and graylog containers fail with permission denied, while elasticsearch boots just fine.

Any hints?

the docker-compose example wasn't well tested and reverted to the previous version with 0c62063 that now should work again
