You can use a custom Docker image for the router component instead of the image supplied with Deis:
$ etcdctl set /deis/router/image myaccount/myimage:latestThis will pull the image from the public Docker registry. You can also pull from a private registry:
$ etcdctl set /deis/router/image registry.mydomain.org:5000/myaccount/myimage:latestBe sure that your custom image functions in the same way as the stock router image shipped with Deis. Specifically, ensure that it sets and reads appropriate etcd keys.
