You can run your scheduler as a kubernetes deployment.
Kelsey Hightower has an example scheduler coded up on Github

Essentially, you can package it up as a docker container and deploy it.
Take note of the way you interact with the k8s API using this package in order to do it this way you'll need to have a similar wrapper, but it's much easier than building/recompiling the whole k8s package.
