How do we handle processes that don't care what port they bind to?

[alexras]

Some processes will want to bind to some random high-numbered port, as long as it knows there are no collisions with that port on its parent host. In EKS, this is trivial - NodePort services take care of the port assignment, and individual processes can just advertise a fixed, lower-numbered port. In Docker and other less batteries-included runtimes, this gets a little trickier, since we'd have to make sure we're not colliding ports at process-start-time.
