/deis/registry/s3bucket key is supplied, the registry

The Deis registry component inherits from the Docker registry container, so additional configuration options can be supplied. For a full explanation of these settings, see the Docker registry README.
You can use a custom Docker image for the registry component instead of the image supplied with Deis:
$ deisctl config registry set image=myaccount/myimage:latest
This will pull the image from the public Docker registry. You can also pull from a private registry:
$ deisctl config registry set image=registry.mydomain.org:5000/myaccount/myimage:latest
Be sure that your custom image functions in the same way as the stock registry image shipped with Deis. Specifically, ensure that it sets and reads appropriate etcd keys.
