If you're only running a few services it really doesn't make much sense to setup Kubernetes. I setup a small cluster a few weeks ago and it certainly was a lot more involved than I expected. I ended up deciding not to use it, since it didn't really add much (for my use case) and I felt like if anything went wrong I'd be in a world of hurt trying to debug it.
Took a lot more time to setup Kubernetes than my entire current deployment system which uses https://github.com/pressly/sup.
However, dockerizing your projects might not be a bad idea depending on what you're doing. I dockerize a lot of my projects since it makes it super easy to deploy when using the automatic Docker Hub builds. Though I did have a problem where Docker upgraded and make all of my existing containers unrunnable.
