Anybody has experience with scaling to zero in k8s?

I’d like to scale deployments of development/test/acceptance environments to zero when not used.

Ideally, I’d like this to happen automatically after, say, 10 minutes of disuse, and for the applications to come back automatically.

Is something like knative the way to go? I don’t need the full functionality of knative (right now) and it’s fairly intrusive on the cluster, but I’d like something like serverless but for real applications, not babby’s-first-nodejs-microservice.
