There are a number of alternatives targeting Kubernetes. I work on one - Project Riff. Others I've peeked at are Kubeless, Fission and Fn. Some are pure k8s systems (like Riff) and others like OpenFaaS aim to be portable across orchestrators.

I believe OpenWhisk is being steered towards running on Kubernetes at some point, but I am not qualified to say. When we looked at it last year as part of the research which led to Riff, we were struck mostly by how many moving parts are involved.

Disclosure: As I noted, I work on one of these things for Pivotal.

OpenWhisk supports Kubernetes as a "first-class" deployment platform. Red Hat have been doing lots of work on this since adopting the project (https://developers.redhat.com/blog/2017/06/07/red-hat-and-ap...).
