Yeah - the containers by default run old Docker - we plan to update our containers with the latest Docker. For the time-being, can you try using the following commands...

Can you remove `docker` from `machine.services` section? I believe that should fix the problem. We are working on supporting Docker 1.7 - should be coming relatively soon.

I have reproduced the process with 1.6.2 here: https://circleci.com/gh/circleci/docker-elasticsearch/55 based on [1]. May I suggest reaching CircleCI support - our support engineers can dig into your build better and debug...
