Yea I had the same question. I'm interested in this but it doesn't make sense for me without the production piece or having it run on top of our own Kubernetes cluster.
We do offer an on-prem solution if you're interested. You could simply spin up a kubernetes cluster on your infra and "helm apply". Feel free to reach out at my email above if you want more specifics.
Curious what other things you're using in your stack?
The infra is scheduled on k8s. Happy to answer other specifics!
