+- `deployment` creates a kubernetes deployment with its associated service and ingress;

 Besides the three modes, the controller has limited knowledge of what the kubefiles
 actually deploy. It expects the following to hold true:
 
 - the `runboat/build` label is set on all resources, with the unique build name as
   value;
-- a deployment starts with 0 replicas and must initially have a

 - the cleanup job has a `runboat/job-kind=cleanup` label.
