We have future 22 plans for this, but it isn't currently available. 23 24 When you run `otto dev`, you'll get an environment with the container 25 running as configured in the Appfile. The use case for this is to just verify 26 that it works for downstream applications using this Docker image as 27 a [dependency](/docs/concepts/deps.html).
