Action using dockerfile without going through dockerhub

Openwhisk can create an action through a docker image in the dockerhub. But the process of uploading and pulling images on the dockerhub seemed cumbersome.

Is there a way to create an action with the `Dockerfile` itself without going through dockerhub? It seems to be possible by building a docker locally on user's openwhisk server.

User will be able to administrate by build own `Dockerfile` with tag like `wsk create action example exec --dockerfile ./Dockerfile --tag user/example`
