Nightly build & push of Docker image(s) to bintray?

[Kenneth Knowles <ke...@apache.org>]

Hello from the Beam project,

We have a Jenkins build that pushes a snapshot jar every 24 hours (if tests
pass) and we would like to have the same for docker images that form a core
part of the Beam project.

Can you advise on the best way to go about this?

I am aware of the use of bintray for Docker repository and my own account
is hooked up, but this would be a CI thing. Any pointers to docs or other
projects doing similar things would be super, too, and I am of course happy
to do my homework if you can offer a pointer.
