Re: K8S submit client vs. cluster

OK amazon not much difference compared to Google Cloud Kubernetes Engines (GKE). When I submit a job, you need a powerful compute server to submit the job. It is another host but you cannot submit from K8s cluster nodes (I am not aware if one can actually do that). Anyway you submit something lik
