It would be awesome to be able to specify some tmpfs volumes on docker images like this:

docker:
      - image: my-build-env
      - image: mongo:latest
        tmpfs: /data/db

or like this with multiple volumes:

docker:
      - image: my-build-env
      - image: mongo:latest
        tmpfs:
          - /data/db
          - /another/path

This will allows to massively speed up some jobs (tmpfs usage with Mongo, MySQL, Postgres… can speed up a test job to more than 100%)
