Really excited to announce this today during KubeCon. It was a really positive experience working with TriggerMesh founder Sebastien Goasguen and the rest of the team. They implemented Knative into GitLab really fast.
you are right that "There is no serverless without (managed) services" https://twitter.com/sytses/status/1072742649700872192 You have to supply the Kubernetes cluster. The Kubernetes cluster can be something like GKE, which is a managed service. So while every serverless function does have to run on someones server you don't have to manage that server.
