Using a custom builder image

You can use a custom Docker image for the builder component instead of the image supplied with Deis:

$ deisctl config builder 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 builder set image=registry.mydomain.org:5000/myaccount/myimage:latest

Be sure that your custom image functions in the same way as the stock builder image shipped with Deis. Specifically, ensure that it sets and reads appropriate etcd keys.
