Thanks, although unfortunately I'm not in the price bracket for Anthos (starts at 120k/year or so I believe).
Alternatively, if what you really want is the ease to manage and deploy containers and automatically scale according to traffic, my understanding is you can always use the open source Knative project with your Kubenetes cluster. This provide you the exact same API supported by Cloud Run and makes it very easy to migrate from managed Cloud Run to on-prem K8s cluster (or K8s clusters from other Cloud vendors).
This doc suggest you just need to enable Cloud Run add-on on your GKE cluster to use it: https://cloud.google.com/run/docs/gke/setup
