I use http-kit as a web server as well. My deployment basically looks like this:
My main function starts my "app", once I have an app instance I attempt to start the http-kit server on a specific port. I do this in a loop, catching all socket already bound exceptions and retrying. Additionally I have an extra Thread watch a pid file to modifications. On modification the "old" app shuts down, releases the socket and the "new" app/http-kit binds it almost immediantly. It is not perfect but it usually means downtime of only a few milliseconds. I hope that was clear enough, basically just have currently running instance watch for a shutdown signal which it will get when another instance is ready to take over. It gets a bit tricky is you want to bind more than one socket, which I do for nrepl and want to do for JMX. I had mixed success with tcp SO_REUSEADDR.
